IT CAME IT CAME!! super happy fun time

wooooooooo im comment # 2!! GJ it’s all downhill from heeeeeeeeeeeeere

Hell yeah!! Im still not going to upgrade till Fastloader comes out.

one step closer the the edge, that im about to break!

OMFG that is so cool!!!!

Pong was never so fun =)

It just hangs up on me.

yeah pong kinda sucks but owell its a playable game so you 2.0oiners enjoy i am going to be here with my 1.50 playing death jr thw hwole night see ya people tommorow maybe the homebre will comout tommorow

Once we have Emulators for 2.0 ill be a happy person, but this is a very good start, i downloaded and everything works good on it!! cheers!! ;]

Kinda makes me wish the 1.5′ers couldnt upgrade because of the shit they put the 2.0′ers through just because they chose to upgrade.

errr #8, pong is homebrew, just because u cant run emulaters and rom doesnt mean its not homebrew. I swear im starting to get fed up with people whos only extent to homebrew is emulaters and roms =/

o well great job on peeps who made this =)

Can confirm it does work on my NZ 2.0 and about holding power for 10 secs to turn off it takes a bit more then 10 secs more like 20.

Finally something to amuse me…

Great to see something on 2.0 Keep up the good work guys!

-TC

FINALLY!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Looking very good. Kind of hard and gets boring after a while but a very good start indeed. Its proceding way faster than I had hoped. Keep the goods coming sosouke

Best game of pong in my life ever. Amazing how it doesn’t need the background and .bin file. Best of all it doesn’t flicker!!!!

SHOULD I UPDATE MY PSP 1.5 TO PSP 2.0!!!!!

This is pretty tight. And to think the exploit came out on Friday and by Monday we are already playing homebrew on 2.0. The future looks very promising. Good job to all the coders on this.

to poster # 17 If you can live with out ur roms for a few weeks (probably a month tops) then yes upgrade to 2.0, theres a good chance we are going to see alot of apps on 2.0 verry soon.

i dont knw how to get it on my psp

i mainly play comercial games on my MS. SO NOW I AM GOING TO UPGRADE NOW!?!?

that totally deserves an
“M-azing” candy bar

from the way it sounds from you gMan, id wait, 2.0s future is promissing, but it seems some people are more patient then others, so you can just relax with 1.5 and when you see the apps you want for 2.0 then upgrade until then just relax some

listen #20 all u have to do s download da file and then place the file in Photo folder of your psp then go to the picture on ur psp and the game will start

Something is odd with it, I don’t need to get into it. It loads as soon as PSP tries to load the preview image (little icon) and the right paddle doesn’t work.

I have a JP PSP 2.0 with JP Firmware.

I will upgrade after all is redone (which will take some time). For now I am gonna sit back and enjoy some good ol fashion games and some new ones later on. I could care less for GTA or Madden (which is crashing peoples system). I am waiting for Armored core. When that comes out I will be siked. Hey aybe we will get a PS emu on this system. It does have the hardware to run it right? SOTN on the PSP would be awsome along w/ FF7 but guess that would be WAY WAY off in the future. I am glad to see a game running. The critics said “you will never get anything to run b/c of the 64kb limit” and “it can’t communicate with the kernel” and all that. Well looks like pong is running just fine ;). Critics -”can I have a nice warm glass of milk, it helps me go to sleep”
Crazy Oldfolks home worker – “how bout a nice warm glass of shut the hell up!!”
(from happy gilmore, hope that made you smile if you remember that)

I’m having problems also, my psp loads it auctomatically when there are no other pictures in the file but if there are it just freezes

YESSSSSSSSSSSSSS!!!!!!!!!! ive waited so long for this!(3 days) but anyways, this is great, now to everyone who helped in making this, i thank you alot and i encourage you to make more games, this is very good, it shows a very bright future for psp 2.0 homebrew! thanx again to the creators of this version of pong

FOR PEOPLE WITH 1.52, I HAVE A HACK. RUNNING STRAIGH EBOOTS FILES.

pkman2k@hotmail.com

I will show you. add me on msn. Also dont update!

I can’t get the download ta come up from the web Site… What happen….

Pkman2k, id just wrather update, get all the new features that sony intended for it, and wait a week or so for Emulaters (since thats the only thing any one around here cares about) and have 2.0 and homebrew, people with the downgrading should be quite too, 2.0 has homebrew its here and theres nothing any one can do, just face it 1.5 is gnna be completly obsolete soon and I cant wait for that =)

pkman2k, send it in to PSP-hacks if its legit and they will post it. Send them proof and the files you used.

# 31 try right click and save as, some windows XP OS just shows you a picture and not the file, just right click and save as, put it in ur psp photos section and it should just fire right up. enjoy =)

lol, never, 1.5 and 1.0 will never be absolute. this new method you are loading pictures to run your game. 1.0, and 1.5 you are running an actually psp executable. what is supose to be ran. what you are running is a hacked up way of running homebrew games. I do belive tho, 1.0 and 2.0 homebrewers will have there own games out there. where its either for 1.0/1.5/1.52, or 2.0.

Yeah buddy!1!! No overflow needed or anything!!!

add me, and i will show you live. proof it works. there still problems. and it will be on later.

sousuke

thank you for your hard work, you’ve helped begin the process

My problem is I click on download pong for 2.0 and it just goes to a blank screen… and it says done is anybody else havein this problem…

well whatever helps you sleep at night, Im just gnna wait for for the 2.0 software to come threw (I’ve had and played homebrew on 1.0 and 1.5) and I like the 2.0 much better. Though it runs from picture files, it doesnt bother me much, I remeber when 1.5 was hacked no one liked it because they had to switch memory cards and 1.0 where all skeptics like 1.5 people are now. History repeats itself and 2.0 is gnna have some great stuff on it, so im just gnna stick with 2.0

lol #40, you have no clue what your talking about. they fix that bug 2 days later. now theres a software that loads 1.0 to 1.5 no swat. straight install. any people these days pre make them for 1.5 no swap. Like WTF? dont talk when you dont know whats going on. 1.5, you have 2 folder, Game and Game%. jesus christ, your pretty dump. or dont bother to look for updates. Youre just saying you like it better because you were an updated before you had a chance to play on 1.5.

1.0, 1.5 they both ran eboot files. 2.0 no eboot. very messed. its not like this is bad. this is great what they found, but is far from good as 1.5. Hell i wish i had a 1.0, so dont have to split my eboot files. 1.0 is the BEST!!!

Got it ta work… Sweet… It won’t be long now… Thanks this was about ta make me go crazy not havin homebrew.. This is a damn good start… Agree #42 wish I had 1.0….

Were getting somewhere now.

finnaly a little homebrew it aint much but he it’s a start. keep up the good work people.

it dont work you need a h.bin file.so any one who said it works is a git!!!!!

Hey you git there must be no pictures except for the tif file GIT!!!

#46 yes it does work. I don’t know how it works without a .bin file either… just drop the .tif in the photo bin and somehow it works. give it a shot. have fun playing pong with yourself.

#46 you need to get your ass straight Why would 40 people say it works and you dont.
oh ya NOOB!

#39 Right click the file -> save as and drop it in your psp photo folder!

if you put the psp01.tif into it’s own dir, for example, ‘Pong’, and put another picture in there that alphabetically is before ‘psp01′, you can navigate the photo menu without issue. once you enter the dir you created, the program runs automaticly.

DOWNGRADER FROM 2.0 TO 1.5 WORKING!

Okay, this is sweet, i am very close to setting up a Workable 2.0 to 1.5 Downgrader.

Just to let others know how it works, or others can try to attempt this.

This is not some fake bullshit method.

Step 1.
Recompile the Wab Firmware changer for the psp 2.0 using the tif to execute. Change firmware name to 1.0

Step 2.
Place in under the psp/games/updates dir a 1.50 update install.

It will think it is a firmware 1.00 and will install the 1.50 over it.

There you go a working downgrader!!

I am still getting the code to compile, and will be launching the code along with the downgrader tif file with it.

46. have you even tried it yet.. you dont need the h.bin or any background.. which is kewl coz i was getting sick of the black there.. even if it was only for a day.. Great work every1 else who made this work.. i mistakenly updated my 1.0 to 2.0 when i first got it.. without even looking to see if i would be able to play homebrew 8( so for me.. this is awesome

Reason i know this works. because i took my current 1.5 change name to 1.0 then reinstalled the 1.5. so should work same for 2.0

Hai Everyone,

question: Does it also work for the (EU)ropean version? Firmware 2.0

Can someone please let me know?

Greetz form the Netherlands

first itought, it does not work on may EU PSP, once pressed X on photo folder it definitely start to access memory stick, but after 6-7 seconds it shut down :( hmmm, i uplugged usb cable, still no succes, then i takeout umd disc, still nothing. one more power off and then, here it comes – IT RUNS!

Man, I’m just waiting for an exploit like before with the 1.0 and 1.5. Really hated when the swaploit came out and I didn’t have 2 ms. And does this go through the Games section or will you always have the Photos outlined when you play?

A down grader wouldnt be a bad thing so I could try out the 2.0 software and then convert back to my 1.5 version just for kicks. I know “who wants a downgrader when 2.0 is being exploited” but actually I do. I would like to try all the new 2.0 stuff but you can expect to wait for months before everythingis as sweet as 1.5 is right now. But it would be fun to upgrade then downgrade at will. Well anything is possible. I am very patient…..(goes back to doing Fluid Mechanics HW)

yeah pong…whats next pac man?…ohhhhh space invaders!!!

Why is it that people in the PSP scene complain so much? The devs don’t owe us anything, we should be gratefull they came as far as they did.

In 3 days from a “hello world” to a game with basic input is quick enough for me.

Thnx, Sousuke!

#59, Pac Man and Space Invaders are two pretty cool games.

Awesomeness. Something that actually lets me control it((even if I have to controll both sides)), just another step forward. Atleast THESE comments aren’t filled with pointless fights and rants((yet)).

Hmm unfrotunately it doesnt work for me:(
i placed the tif file in the photo directory.
Open the directory and bam freezes

whoops correction i had to hold X
it works now
great job guys

Interesting post by Sousuke (pong’s author) on QJ forums, he says that the 64k limit is just a rumour, it’s just the default amount overflow.tif loads which can be changed to load 1MB or more.

(Hope to be playing Doom on my 2.0 PSP within the week)

Hey 62, i just updated my 1.51 to 2.0 and i got the hello world to work but i got the same problem as u, bam freezes crap..any suggestions…?

nothin really that special on v2.0, i have it, i would rather have homebrew

i cant seem to dl the file. when u click on the link it bring u to another web page with a quick time logo “Q” and a question mark on it… wat is wrong??? can anyone pls help…

#67, right click on the file link and “save as”. Your browser is trying to play the file or something.

67. Right click on the file and save it.. or even easier just load up the URL on your psp and tell it to save in the photo folder 8)

Finally,there’s somthong for PSP version 2.0,i been waiting for so long,please keep coming out with homebrew for 2.0.good work.

i want more more more more

Excellent work – this is truely excellent. Congrats to all involved.

Sorry nevermind got it to work…ahhh is there a way to change the black wall paper?

73. yeah first usb to the psp and del the pic’s and put your background in.. the on the psp set it as the background.. usb back onto the psp and copy the psp01.tif back there and its sweet

this is nice, does anybody know how it works?

great work
let’s go to the great games now!!!!!

Does anyone have any idea how to change the speed of the paddles or the ball? it’s difficult.

Really good job!

does this mean that i can run and play emulators from my memory stick like in 1.5?

i dont have the psp yet.. tomorrow i will get mine with 2.0!

thx!

80. right at the moment.. no you will not be able to play games off yer memory stick.. well cept maybe a few small homebrew games.. give it a few weeks maybe a month or 2.. and who knows you might be able to do

THX A LOT NBR 74!!! GOT JESSICA ALBA IN THE BACKGROUND INSTEAD OF A BLACK SCREEN AWESOME!, READY FOR HOMEBREW!

keep up the good work..

Works on my EU PSP, didn’t work when I had USB and UMB plugged in though. Very cool. Can’t wait for emu’s and divx players ;-) Its like a mini xbox in the making.

that’s so cool,try again developers

works for me, only when its the only image in the folder :P

good work, keep it comeing.

Nice work to the developers. Im sure we all be playing games from the memory stick. Ill just wait paitently unlike those other idiots that keep bugging you with world’s dumbest questions lol. I laugh my ass off reading some of the comments on this site.

Cheers to the developers!

Great work!!
#85 Is there a working divx player for 1.5? I would love to see mplayer on my PSP! I hate having to reformat my movies!!

89 Why not just reformat to mp4, the files are much smaller and if u have a good 1 or 2 gigger that’s more movies. Besides, there is not a divx player for psp, sorry.

u guys say GREAT WORK AND IT WORKS!

how do you try it? with an emulator or what?

I dunno hwo everyone is running this without the frame_buffer background… I always get my PSP frozen, but If I use the buffer background it works some one type a short tutorial on how they got it to load w/o the frame_buffer please!

In adition to my last post, coudln’t someone make a homebrew TIF viewer so u coudl view TIFs on 1.5s and test 2.0 games out, or will it not work if started up in kernal mode?

hey! it works on the european version to!!=P

nr.#92. just copy the file and put it in PHOTOS and then when you start your psp go to photos and press x and the game will start automaticly!!

this is great i had this befor it was posted here! This is a great start to homebrew on a 2.00 psp now i’m just watilg till the emus come out.

i have a question: does this game run in kernal mode?.

#95

which game starts automaticly????

Umm could someone put another link to it? when I click on the link here it shows a corrupted quicktime object :(

oh yeah great job peeps who made this!

ohhhh yees keep it coming coders!!!!!!!!!!!!!!!

#98, right-click on link a choose, Save Target As …. or simply read all comments and you find out, your “problem” was already answered

anyone know if this works on 1.51?

http://www.1122studios.com/

A Downgrader is said to be made and downloadable on that page

dont kno shud not at least i dont think so

ON THE 29TH!! IS THIS FAKE?

Has anyone checked it yet? The team 1122 said some time ago that tehy want to release a downgrader. Now they have released one. Is it a fake oer not?

http://www.1122studios.com

By the way: I believe that #29 IS FAKE! because his email doesn’t exist!

nO IDEA but if it’s real i’d definatly try it

It wont work on a 1.51 because they can’t read the .tif image format. Thats one of the 2.0s updates.

Luckly I have a 1.0 :)

Has anybody proof if this downgrader really works? I also heard about they would release something. Sounds quite serious. Has anyone tried this 1122-Studios stuff yet?

#109
whats the problem?
1.51->2.00->1.50 (if downgrader works)
but i’d rather enjoy the ancipitaion then downgrading…

#90
where’s the flexibility, when you have to reformat each movie you want to see? Besides I could use my Cowon IAudio X5 (30gb) as an external Harddisk.

i think it’s real :)

@ 113: But it’s a success! An you should real the news from #106

110#It Doesn’t work it said corrupt data,I put it in the game folder under the map downgrader….has somebody else try it if it works please tell me i’ve got ver2.00

#113
shshsh

its 13.575 MB file with the name
EBOOT.PBP
what now? copy in photo folder?

sousuke GJ IT works very fine!

the downgrader is not granted tho

#113
shsh.. you must be soooo stupid!

its a 13.575 MB EBOOT.PBP file
what now? copy into the Photo folder?

You have to copy the eboot.pbp in your game directory

in the subfolder UPDATE. And than execute it.

Can someon please tell me what to do with the eboot file from 1122.where do i put the file the game of photo???

hmm could someone post the filesystem of the memory stick?
i didn’t format it on the psp…
i just created /photos…

THNQ 121

I dont know what the fuss is all about really…

This exploit is purely for homebrew and not for ISO loading like what some are expecting.

This exploit only lets people run binaries in “user” mode and not in “kernel” mode. Not much use for anything like Fastloader or UMD Emulator even if they did manage to get these programs to run in the 64k memory restriction of this exploit as there wont be enough access to the PSP’s operating system to patch the system.

The biggest discovery since the exploit was releaved was the ability to dump the PSP’s BIOS. That can reveal some secrets…

Cheers.

Again: Put it in a folder called UPDATE. Than put the folder UPDATE in your GAME folder on MemoryStick. Press the home button. disconnect USB cable. Execute the Update in Gamefolder!

does it delete the gamesaves when i format my memory stick?
or does it put them in the correct folder?

This Folder: G:\PSP\GAME\UPDATE

@ #125 I’m with you in general. But I think that new downgrader from 1122 might be the greatest development yet.

but does the downgrader works did you try it “somebody”128#

#125 So another better exploit has to be found, which is easy now as the 2.0 BIOS has been dumped?

#126 Did it downgrade?

Me not. I myself am Stuck with 1.50 anyways. Maybe Shrink has… He got the news anyways… Have you tried it yet, Shrink? Does it work?

is it even completed cause it say available on the 29th

I think they got the date wrong because it IS available yet.

126# It doesn’t work it said:The system software on your psp system is version 2.00 there is no need to update.I did exactly what you said i put it in the game folder under the map UPDATE and then i see this…

Shit. Which Version do you have? US/EU or the JAP?? Maybe it depends on the 2.00-Version. There is a 2.00A and a 2.00B

I’ve got a us version
This is my System Information:
MAC Address: 00:01:4a:44:f0:7A
System Software:Version 2.00

Yes. The japan-Update is 2.00A. The EU/US-Update is 2.00B

So there is still hope it works with 2.00A. Anyways it might be possible that they will really release the file on 29th of September then…

Does that mean i can’t downgrade i’ve got the jap version???

ooh man anyone gotta JAPANESE PSP TO TEST IT OUT ON?

why all “downgraders” till consist of two parts?!? one to “trick” PSP to run old update and second = old bios itself; i believe that EBOOT.PBP is nothing less and nothing more than just pure 1.50 BIOS

Maybe. I don’t know. Might be possible it works with 2.00B than. (not with 2.00A which I wrote falsly). It could also be that the real file is released September 29th.

141# What do you mean it works with the 2.00A??i can’t downgrade please explain i’m new

@ #143 we need a US/EU to test it out. Because it might work on 2.00B (Njongkariu got the 2.00A japan version)

@#146: The Post #141 was my fault. I meant 2.00B US/EU version

Just copied the 13mb file in my games/update directory. When I open the dir, there’s a ‘Update v1.5′ option.
I have a EU 2.0, but I’m a bit weary of doing it. Think I’ll wait for the 2.0 loaders. Did anyone have the guts to X it? And, what happened?

The file from 1122 Studios looks really quite like the original 1.50 Firmware file. So I don’t think this is a downgrade YET !!! Maybe they give us the Downgrade on 29th as the text below says…

Never mind ^^^, lot of responses while I was reading and typing ;-)

I tested it on my EU PSP 2.00 ,but it says :The system software on your psp system is version 2.00 there is no need to update.

I believe that EBOOT.PBP is nothing less and nothing more than just pure 1.50 BIOS!

Thank you. I think so as well. Maybe chack back on September 29th. I hate to be stuck with 1.50. I want to be able to up-and downgrade between 2.00 and 1.50. I don’t belive that Loaders on 2.00 will be possible. The little homebrew stuff on 2.00 that was made is shit. You can only write programs smaller amount than 64k so a loader won’t be possible with this hack.

yyea tru but who knos they might find another bigger hole in the 2.00 firmware

#152
yes, and how should this suddenly work anyhow? i guess we will have to wait for the magic *.tif from 1122 which changes the current firmware version in the bios…
and then it should be possible to get back to the menu, so you can do the downgrade (or simulated upgrade 1->1.50)
Until now i could only get back to the PSP menu with the starfield demo, with all the others you had to shut down the PSP…

I don’t think you need a tif file for a downgrader. Sony doesn’t need one for an upgrade as well. And with the decryption of 2.00 done yet, people might have found a way to tell the PSP THEY ARE SONY… if you know what I mean.

#150
Doesn’t it have to comunicate with the kernel when you control the bars in pong?
Besides: Once the firmware is dumped you can find more exploits…
Just wait and see

WOW! I just woke up today and saw that there is already homebrew for the psp 2.0. That makes me so happy to know that I got a 1.5!!! =D LOL. BUt I hope that all homebrew will be on 2.o so I can upgrade.

this was out a few days ago at pspupdates

well i hope it’s true tho

Hey guys,
It works :D:D:D thanks ps2dev.com. Good luck everyone.

155#Tell me please i want to downgrade also…

is pong higher than 64kb

Ah, this is the first clean commment board I’ve seen on the site… No “It didn’t work my firmaware is still the same” or “How this works?”, of course few of the last ones, but that is understandable, unlikelyy tens and tens of them in I.E. 2.0 Dumper comments

Back to topic–>

If it is true that there really is no 64k limit… GJ everyone :P But it sounds very limiting… I think there is no point in keeping 1.51 or 1.52 now but I’ll play it safe…

#156 he was talkin about the demo

WHOA! Finally i can play pong on my psp. soon i will be able to play all the crap games YAY!

#158 What the hack are you talkin’ about? Didn’t understand a word. I think there is a 64k limit because pong is a really small game. And as you can read in the BROWN-SCREEN-NEWS from yesterday the 64k limit exists.

ok question is can you cram a version chnger into 64kB. Then people can downgrade and thats that. Also I thought you couldn’t “access the kernel” but now pong is workinh with controls. Who knows what they’ll do no that v 2.0 is dumped. Maybe they will pick it apart. Its too bad this hack doesn’t work with movies just like pics. Then you could have unlimited amount of space but then again I don’t know what I am talking about when it comes to this stuff LOL!!!!

mine opens on its own. i scroll down the the bottom n bing it opens on its own if i got pong in its own folder the psp crashes n if i just got the pong file on its on in the photo file it crashes so i hafta have a load of pix in there n scroll to the bottom to open it i aint got the choice to press X to open it

#162
Yes thats the central point
Make a version changer tiff so you can downgrade..
the WAB version changer is 79kB
(as RAR…)So when you consider that it was coded by WAB (was it?), a Pro should get it into 60 kB.. i guess…
Speculating is great fun!

I wonna to play Snake =)

Yeah snake would be awesome

buy MG-Acid for a Snake :)

over at http://www.pspupdates.com they have got a button swapper for jap psps which swaps the o button so its x pretty good i just did it

for all the women that want to play snake u can reach down my pants…lol…

I just noticed something about the button swaper for ver 2.0 i just told you about. You have to put a BIN file and a folder which is 500KB in the ROOT of the memory stick and when its running its its using the files in the folder to flash the psp.

So if i’m correct its using the BIN file as a feeder to use the files in the folder.

which means that apps bigger than 64KB can be run on ver 2.0 psp if they use the BIN file as a feeder to a folder.

#156 I’m talkin’ about the demo man, I don’t thing that the downgrader works. It is bullshit that they say it works. I think it is good to wait till they make more things for 2.0.

Good luck guys.

Yeah 64 k max for fastloader would already be tough to get a run on the 2.00

Is better to come with a downgrader, don’t forget the 1.50 can run much bigger homebrew apps

Soon it will all be clear…

i give it just a couple of days… since psp went euro the progress has been on fire… this is great and it looks very promising… GJ to all working on this!

Maybe you’re right, having the version changer to let’s say change the psp version to 1.0, maybe this will enable the 2.0 guys to downgrade their psp to 1.50

It will be great!

TO STOP THIS FREEZING JUST PUT YOUR THEME BACK TO THE DEFAULT (the kinda purple looking os)
then it should never freeze for ya!!

Dont plan on any good emulators being any better on 2.0 than 1.5, its going to take a lot longer than a month, but if sony keeps updating and people are just keeping upgrading. the existing programs will get set aside and try to start hacking the 3.0 or whatever, its going to be back and forth for like 3-4 years untill it finally dies and sony makes something else and no more updates for the psp

161: Look at the comment #64. Never know about that guy then…

I don’t think it’s a rumor that you can’t run larger tifs than 64k. Why would you say they give us PONG as first game? It’s a fuckin small thing that’s why.

Back to comment #52:

Recompile the Wab Firmware changer for the psp 2.0 using the tif to execute. Change firmware name to 1.0

How to recompile to a TIF file? What software r u using?

the link isn’t working for me

What in the hell i found that game on psphacks.com on sunday and submitted it what the fuck i should be getting the credits for that not that person!!!!!!

#181 just go to psphacks.com and download that i found that there on sunday!!!!!!!!!!!!!!

never mind #181 the one i found was different!!!

And #181 you have to left click on the file name and clickon save as.

Well…I guess I should quit the project on 2.00….and I almost got it working on 2.00 (it works on 1.50

I didn’t see anyone with v2.0A but the downgrade for v2.0A doesn’t work it says no need to update

…oops

I told you: Wait till September 19th. Maybe they’ll release the real downgrader (their page at least says so)

Hey, Nice work! Finally some good stuff for the PSP!!! Bout time someone got this working!
Now all we need to do is get some better games goin!
NICE WORK!

is it supposed to start up rite when i click on photos?

cuz i cant look at my other pics.
and is there a way to exit it? with out reseting my psp?

On my PSP When i go to it i dont have to press anything and it just starts up once i scroll down to it. The only way to get out of it is to reset your PSP or tae the battery out. Taking the battery out takes less time but the better idea would be to just hold down the off switch for the 12 or so seconds it takes!
CYA!

With your other problem where you cant look at your other pics is because it may autorun when you go to it like my PSP. So i think that the game is the first one on your list so as soon as you enter PHOTO it may start instantly.
Try putting it at the end of the list in the PHOTO folder on your PSP!

no i did that didnt work.

i tried to put it in a folder but no that didnt work either

its wont come out!WTF!I click it on my Mac and nothing works!

when i click ping it brings me to this quicktime plug-in thing and i cant download teh pong

Dude go to my website to get 20. to 1.5 downgrader! sambar5.tk

at least were making progress with cracking 2.0. when will someone hack a fastloader 4 it?

well, my story has a happy ending…

so i went and purchased a psp.. since I didn’t know about homebrew apps, I went ahead and did the moronic thing of upgrading from the native 2.0 to 2.5..

after I found out about psp-hacks.com, I packed my psp, went back to Target (where I bought it) and exchanged it for a new unit..

now I have a psp with firmware 2.0 again!! time to finally downgrade!

I was wondering, this doesn’t work on 2.01 I know that but since the similarities between the 2 versions are many, then we might be geting close to get that one too right?

Does this mean theres gonna be emulators for the psp 2.0?

is there any hombrew stuff for 2.01 and none of the downgrading stuff works my norton pics up the pspbrick virus every tiome i do it, so i diabled it and it didnt work!!!1 absoloutly useless!!! lol. has anyone got any succesfll downgraders or any 2.01 homebrew games

Cheers Craig

hope there will be more soon like doom
