PicoDrive — SEGA Genesis & SEGA CD Emulator Released *Updated*
greg | November 18, 2007
Update: Version 1.35a has been released. The quoted paragraph below details the changes…
Well that test-a-bios-and-you-are-screwed bug was quite a serious one, so I’ve done an update:
fixed a bug which prevented to load any ROMs after testing the BIOS.
fixed incorrect CZ80 memory map setup, which caused Z80 crashes and graphics corruption in EU Mega CD model1 BIOS menus.
added additional “set to 4:3 scaled” display option for convenience.
added an option to disable frame limitter (works only with non-auto frameskip).
Something new to occupy a megabyte or two on your memory stick — PicoDrive! The readme details everything you must know about Notaz’ latest SEGA Genesis / Mega CD emulator. Still requires a bit of work, but works well no less.

This is yet another Megadrive / Genesis emulator for PSP, but with Sega CD / Mega CD support. Although it has been originally written having ARM CPU based devices in mind, it has now been ported to PSP too, by replacing ARM specific parts with portable C code. The base code originates from Dave’s (fdave, finalburn) PicoDrive 0.30 for Pocket PC. The Sega/Mega CD code is roughly based on Stephane Dallongeville’s Gens.

first post for the new emu… booya!!!
First post to call you a DumbAss!!! boooya!!!!
booya you fags
grow up
Nice !!!!
Nice!!!
where to get the sega cd games ?
finally. and to all of those who said a sega cd emulator for the psp wasant possible your all idiots. saturn, yes, thats not possibe (but then again barely anything can run a saturn emulator), but theres no reason the psp cant handle sega cd games.
I wouldn’t say saturn isn’t possible…
they said n64 wasn’t…that was disproved
they said psx wasn’t…that was disproved
if both those can run, saturn is arms length aways imo
It might be slow like the proof of concept psx emu, but i think it could happen
the PSP can not and will not ever emulate the Saturn. To emulate a Saturn on a PC requires I believe a 2.8ghz processor
lmao…look one release up on the mainpage.
all the naysayers just got handed their own shit for breakfast
you really dont know just how difficult saturn emulation is, do you? i mean hell, pcsx2 has lower requirements than the best saturn emulator last i checked. not only that but the saturn was absolutly THE WORST system from a hardware standpoint. a horrid bitch to program for even, why so many devs left the system high and dry and went to work on making games for the playstation instead, easier to program for. emulating it on the psp IS impossible, the xbox cant even emulate it so why do you think the psp will be able to?
there’s a downloadable early version of a sega saturn emulator for the psp…I wouldn’t say anything IS impossible…

You cannot emulate Sega Saturn is real time or even close to it on the PSP. The 333mhz MIPS cpu isn’t capable of emulating the Sega Saturn’s multiple CPUs and VDPs in real time or anywhere close to it.
Just consider how demanding PC emulators of Sega Saturn are and how inferior the PSP is to such a PC. Either way, no amount of fanboyism or dick sucking of an emulator author will get you Sega Saturn emulation with a good framerate.
man u guys r just evil
get a life u nerds
and vote for the legalization of marijuana!!!!!!!!!
Snatcher on the go, here I come!
^Exactly!! I’ve always wanted to play it! Though you know if you have a real SegaCD you can play burned games without any hassle.
I have a mega cd (segacd to you :) so i dont need the sega cd support :)
Does this/will this have 32x support too? I’d love to play Knuckles Chaotix as I never got the chance. Still Sonic CD might be fun too as I never played that either
This REALLY tics me off!
I JUST bought a CDX system (to play burnt Sega-CD games) off Ebay…
And now I can play them Perfect on my PSP!?
PS. I love this Emu. Been playing sega-CD games for an hr. now on it…
Video type games dont seem to run well on it….for now
and i can get MK to run on it?
Where do i get roms for sega cd?
Dont ask for roms or iso’s here.
I’ve recently installed 1.50 kernal v2 and all my homebrew is working again – This PicoDrive has replaced my DGens indefinetly – I’m now playing Sonic CD and it runs great!
All I can tell on the WHERE can get games, is use google. But, this emulator, while it does need SOME work, runs AMAZINGLY well.
I’m guessing this won’t work 100% on a PSP slim w/ hacked FW, since it can’t run the 1.50 home brew?
you can run on slim since it is for 3.xx firmware well it works in the game folder for 3.71 m33 firmware anyways
Ok downloaded the game Shadowrun For it..Didnt work. Gunna find sonic and get it.
Alright. I cant get games to run on this thing. I load the .iso by dragging and dropping the folder into it. Theres a bunch of weird stuff in the folders but im sure there suppose to be there. any help?
I read the readme and it doesnt make any sense. So if i could get some help. thanks
Finally a Genesis Emulator that runs all my games at FULL SPEED 0 FRAMESKIP!!
Now for Snes TYL to pull their finger out!
Agree!!
if anyone has the emu working have u got night trap ,sewer shark,double switch,or any of the FMv games working at all because thats all i want to play.DRACULA UNLEASHED of the psp i can only hope.and also since the roms are so big does anyone know if u can strink them down or something.this is a great emu and its going to make me go buy a 2 gig mem card just for it.
Cool i’ve been using picodrive on my nokia phones for a long time. Now on my PSP yahoo!!!!
I can’t get the Emulator to recognize the BIO’s on it’s own. I did however tryed a different approche and got it to work. Ideas anyone?? I just played Monkey Island and Space Adventure! Awsome!
I read the readme and it doesnt make any sense. So if i could get some help. thanks
Really All U Need Is Sega Cd Bios And a Sega Cd iso With The Mp3 audio For It and I Almost Cried When Snatcher Started Up Running Flawlessly
Thanks Notaz’ And Hideo Kojima (for Snatcher)
just got it woring on my slim! plays sonic cd flawlessly! im giving up sex………….just kidding
Dont lie to yourself you have never had sex you nerd
STFU and GTFO
Need less of you flame-tards here.
need less of your lame ass comments. just here commenting on the emulator and i get screwed for it.
wtf?
welcome to the real world
haha lol ive been married for 6 years so ive probably had more sex than u. but anyways sewer shark works freakin sweet too.
what’s his name then
stupid emu :-l
you mean “emo”
playin sonic cd right now ,wow intro is perfect ,sound is also brill ,man what a release .. iv been waiting on segacd emulation on psp for so long and it was well worth the wait,im sooo happy with this release i think a donation is on its way.
again thanks soo much
i try’d some megadrive roms on picodrive and wow ,they all run super smooth and all the games that didnt work on gens work fine like EA sports titles and dragons fury ,also i have/used all sega emulators for pc and i have never saw once an emulator boot (virtua racing) megadrive version as its not supported and no one has ever emulated it as its hardware is unknown yet picodrive boots it and you can see menus and here music.
superb emulator for psp,32x emulation would only be nice for mabe 2 or 3 games so its really not a big deal,while segacd has many top games.
NHL 98 doesnt work as it freezes at the EA Sports screen. I know my rom is not bad as it works on my xbox and my other portable gaming system which runs pico also. I couldnt get it to run on the dgen either. Most of my other roms i tried have worked fine though
if anyone is having probs getting iso’s to work read this ..
when you have segacd iso it should have audio files,between 5 or 50 of them,the audio files should be in mp3 format.
the name convention of both iso and mp3 is important but the titles/names can be what ever you like example ..
iso sonic cd
can be named sonic.iso or abcd.iso
but the mp3 should be named the same in regards to the iso like this …
sonic.iso
sonic_02.mp3
sonic_03.mp3
or
abcd.iso
abcd_02.mp3
abcd_03.mp3
it doesnt matter what you call the game/iso as long as the mp3’s follow the same name.
track 01 is always the iso so your audio always starts at track 02.
hope this helps
could someone tell me where do u put the bios and iso at on memory card at im a noob at dealing with iso and bio also do iso come in files looking like your other system roms?So PLEASE help me out.TY
they go in the same place as the eboot(main folder). just make sure the bios is named correctly or it wont recognize it.
so u dont have to make a rom folder for it?i only know how to put regular emu on (nes,dgen,etc.)is this the same why.could u email me a detail install please at gipsonfamily03@sbcglobal.net
What does the bios have to be named?
NM got it lol…this thing plays pretty flawless its awsome, so far I only tried Earth Worm Jim Special Edition tho.
Lunar Eternal Blue!!! Cant wait
Bloody AWSOME! Great news for us in the UK!
Sonic CD possible at 100%ish on this emu at all per chance? gonna give it a try – dam great work!..Any chance of support for the 32x in the near future??.. I really think that knuckles chaotix and space harrier would top off the immence PSP gaming experiance =]
yet again bloody welldone to you all!
OK so I cant run sonic. IDK what the hell im suppose to name what? Where are the iso and bio files what do they look like ???
yessss I know this site that has sonic cd roms to…think education+emuation…if you added those two words togthor and put .com thats a good site….cant help you more than that dont want to get in trobule…but that site has a working sonic cd (J) and (u) roms….gona try it later my self…
Do the Lunar games work on this? Anyone tried?
Lunar Eternal works great! The emulator works better on PSP as on GP32x
I can’t seem to get the EMULATOR to recognize the BIOS. Can someone shine some light on the subject please!
Hey =]
you naming the BIOS right? just rename them with these =]
US: us_scd1_9210.bin EU: eu_mcd1_9210.bin
JP: jp_mcd1_9112.bin
Hope this is of some sort of help =]
Seanus
Thanx, but it still won’t recognize them. They go right next to the e-boot, right? or in a different folder?
Worked flawless on reading the bios, game, etc. Tried to load Mortal Kombat and after the intro it freeze’s, skipping the intro makes it freeze :(. Trying sonic now.
cant get lunar Star Story to work… anyone else having this problem?
anyone having problems running some segacd games needs to enable (megacd options) (better sync) this option is needed for some games that have fmv in the intro or through out the game,you can enable it to get past the intro then disable it when playin the game as it does slow down the emulator.
there is a a fix to the above,once (better sync) is enabled you can then disable (emulate z80) from within (advanced options) this will speed everything back up enabling fmv games like road avenger and cobra command to run much faster,tho if you do this you will need to set the renderer to (fast) and also frame skip to (2).
compatibility for segacd
—————————
sonic cd – snatcher – road avenger
cobra command – shining force cd
heart of alien – dracula unleashed
dungeon explorer – ecco the dolphin cd
final fight cd – keio flying squadron
lunar- mad dog mcree – mortal kombat cd
prince of persia – rise of the dragon
robo aleste – sol feace – thunder strike
time gal- soul star
all working fine tho some games need different setting to boot or to run at a good frame rate.
im testing another 20 segacd games the nite
I still can’t get the emulator to recognize the BIOS even after I re-named them! They go right next to the E-Boot… right? or do they go in a different folder? …so sad…
SWEEEEET!!! I got it!! All I did was removed the .bin from the bios files! and PRESTO!
sonic cd is runing great. I sugest useing the (J) rom. the music is better
RRoad Avenger freezed up for me.
Sonic works gret tho :D
Pitfall works flawlessly
I’m having problems with the audio and my game wont play. It’s in iso/mp3 format. I have it renames as DarkWizard.iso DarkWizard_02.mp3 DarkWizard_03.mp3 Darkwizard_04.mp3 etc… The iso loads, but then I get an error that the mp3 files aren’t in the right format, that they should be 44100K. They already ARE. I’ve messed around with every combination of CDDA and PCM off/on config, and the mp3 files still won’t load. I’m really frustrated. HELP!!!
I can’t get my game loaded! I’m using iso/mp3 format. They’re properly named DarkWizard.iso DarkWizard_02 DarkWizard_03 DarkWizard_04 etc. The iso loads, but I get an error when it gets to the mp3’s. It says “Wrong format, must be 44,100″. The thing is, they already ARE! I’ve verified this with Nero media player and Winamp. I’ve tried mesing around with the CDDA/PCM settings, using every combo there is, and the mp3’s still won’t load. Someone HELP!!!
Problems with sound …
use program called (Media coder google it)
Just open it, set the ‘LAME MP3′ tab on the right to CBR, Stereo and somewhere from 96-128Kbps, go to the ‘audio’ tab on the left and set resample to 44100, set the output folder up top, hit ‘add’, choose all the mp3s, hit start and wait.
i got this information else where and had to sort some of my own mp3s out for segacd isos and this method works great.
detonator orgun – puggsy cd – f1 circus – bc racers – slipheed – starblade – jaguar racer – battle fantasy -space adventure cobra – road rash cd – ecco the dolphin 2 – popfull mail – lunar 2 – sonic cd (us) afterburner 3 – battlecorps – flashback cd -
all working so far but roadrash seems very slow unless frameskip is on and also needs the sync fix
anyone playing sonic cd should use the usa iso as it runs much smoother than the pal 50 uk iso,if you dont like the us music just change it with uk music.
i love this emu but i would love to see a few added options but i hate to ask …
1,set frame rate to adjust (ability to set to 50 or 60 fps not dependant on bios.
2,scanline (makes fmv games and intros look much better.
3,overclock volume (i find this emu very quiet)
4,include more button setups to (better sync) can be mapped to a button (needed mostly for intros)
i really cant think of anything else this emu needs, its superb.
Guys love the fact that there is no a mega cd emu and saturn emu, can someone point me in the direction of how to transfer my original mega cd games on to psp and also it will not detect my mega cd bios, i have tried 3 different ones and putting them in teh correct folder, ANY help would be welcomed, cheers
bios files dont go in a folder, they should be in the main emu directory folder along with the emu eboot, bios files should also be named correctly.
you can use nero burning rom or any other program that lets you create an iso of a cd or dvd disc,but in the case of megacd and also sega saturn you should create an iso and also rip out the in game audio,nero does this nicely and i sugest you use nero.
in nero options ,choose nero burning rom,not nero express or smartstart,once the window has opened click on EXTRAS at top and choose SAVE TRACKS ,make sure your game disc is in the drive and it should load up showing you track 1 iso and then track 2 and track 3 and so on.
from here you can rip the iso file and the audio,you can rip the iso as nrg (nero iso format)
but you shouldnt choose nrg ,you want raw iso and for the audio tracks choose mp3.
once you highlight your iso or music track choose
the file type format to convert to,this is done through the output file format tab in the middle of the window,so if you have the iso highlighted you will be able to change the output format to iso or nrg,same with audio,mp3 or wav or whatever .
once you have ripped your game disc ,you should have 1 iso and several mp3 tracks,they should all go in a folder together and should also be named in a cetain way.
the iso should always be track 01 ,but it can be called what ever you like ,soniccd_01.iso
(( _01.iso )) is the important part and the audio mp3s should follow the same name.
soniccd_01.iso
the mp3 tracks should be named the same
soniccd_02.mp3
soniccd_03.mp3
and so on ….
when you have ripped your gamedisc ,iso and mp3 tracks ,nero will have numbered them for you, you should keep them in that order as thats the correct order the tracks play on the original disc,so you only need to rename your iso and mp3 tracks slightly but keep the track numbers.
this method is the exact same with sega saturn games and this is how pc emulators run megacd and saturn games.
when I try to load cobra command, it freezes at the end of the sega intro. I’ve had this problem before but don’t remember exactly what I did to fix it, Iremember it had something to do with formatting the sega cd ram.
If anyone knows how to fix this, let me know.
wake up man,,it wont work
