PSP x86 Emulator Released

Alias420 | August 13, 2005

Bochs the sourceforge project to emulate x86 architecture amongst many platforms has been successfully ported to the PSP. Bochs is capable of running most Operating Systems inside the emulation including Linux, DOS, Windows® 95/98 and Windows® NT/2000.

How to make it work:

1) Create your bochs image and configuration files. I highly recommend installing the OS on a PC before moving it to the PSP (unless you want to spend the next 10 years staring at a progress bar). You can also download some readily available images from here.

2) Download and unzip the files below.

3) If you have 1.0 firmware put the EBOOT.PBP file under the GAME directory (e.g X:\PSP\GAME\BOCHS where X is the PSP drive). If you have a version 1.5 firmware you need to repackage the file using KXploit. I haven’t tested it on a v1.5 firmware so I hope it works. It won’t work on newer firmwares (v1.51, v1.52, v2.0) because it’s impossible to run homebrew applications on them at this time.

4) Create a directory named VM in the root of the memory stick (e.g X:\VM).

5) Copy the disk images and bios files anywhere on the PSP.

6) Edit the bochs configuration file so it will point to your disk images and bios files correctly. Note that on a PSP you have to use the “ms0:/” prefix as the root of your filesystem (see the example configuration in the downloads). Also set the amount of memory your VM will use. Be sure to set it to about 8MB as the PSP will crash if you try to use more (the PSP has about 32MB of RAM total).

7) Rename the bochs configuration file to “bochsrc.bxrc” and put it under the VM directory. This is the only real requirement as the path to the configuration is hardcoded. You can put the rest of the files wherever you want as long as the configuration file points to them correctly. See downloads section for sample script.

8) Run bochs and hope for the best.

To run your own games in DOS, download WinImage here and open c.img from FreeDOS. Extract autoexec.bat, add the commands you would like it to run, ie: prince.exe (prince of persia), save the edited autoexec and put it back.

I don’t even want to fathom how slow this must be. Bochs is unsuitable for running any real world apps on high end PCs, I somehow don’t expect anyone to get much use out of it on PSP. It’s more of a good debugging tool than an emulator meant for running anything…

HOW TO GET IT TO WORK ON 1.5!?
Here how:
two methods of going around this.

1) Download kxploit from the download section. if you can’t find out how to it. then you shouldnt be using a computer. Read instructions. but it should be common sense.

2) Take current eboot file. extract the data.psp file and rename it to eboot.pbp. create 2 folders. 1 called ‘NAME’ another called ‘NAME%’. place the eboot file with the data extracted out into that folder.

now put the data.psp file(which was then renamed to eboot.pbp) and put it in the ‘NAME’ folder.

but if your just a hard core noob and want the easy fast way of doing it. just do method (1)

Comment by thanhda
2005-08-14 05:00:40

lol to you noobs about the dos one. It finishes at c:\

WHEN YOU SEE “C:” THAT MEANS ITS SUCCESSFULLY WORKS.

How old are you guys, have you never seen dos before?? at this point you are supose to do what you want, like run an exe or enter a dir. whatever floats your boat. BUT!!! because we dont have a keyboard to type all this out, you will have to edit the bat file to pre build it to do whatever you do.

PLEASE NOOBS, READ THE MOST OF THE SITE AND READ TXT FILE!!!! IF YOU DONT KNOW HOW TO USE DOS, OR EVER SEEN IT IN YOUR LIFE, DONT USE THIS PROGRAM.

Pick up a book on Dos, and learn how it all works. its like MIRC.

READ THE LAST PARAGRAPH

“To run your own games in DOS, download WinImage here and open c.img from FreeDOS. Extract autoexec.bat, add the commands you would like it to run, ie: prince.exe (prince of persia), save the edited autoexec and put it back.
” – end quote

This mean, open the autoexec.bat file in text editor, and put your command lines in. eg.

—–start——
c:\
cd bin
cd games
test.exe
—–end——–

this means you have to place the test.exe file in the :\bin\games\ folder int he image file.

if you have problems with this. i suggest you go to chapters or any computer book store and buy how to use dos for idiots or something.

sorry for sounding rude, but this should be common sense.

i don’t understand why there are so many people trying to use dos for psp who don’t know wtf dos is. i’m curious, what made you want to do this? I thought it was all about means to and end, but you have no end in mind. it seems ridiculous to then employ completely arbitrary means for no particular reason. anyway.

LMFAO. honestly, why are you even attempting on using this program, WHY do you want to use it? this tool really isnt that usefull at all, at this current state. its a good step for developers. but you guys obviously dont seem like developers. So Why the **** are attempting to use this. Go back to your emulators. and stop being a noob.

okY TO #33. just type this
—————-
PATH C:\BIN
test.exe
————–

place an exe file name test in the bin file and see if it work. or even try running the existing exe in the bin folder.

WHERE WINDOWS 95!?!?!

Here the answer for you guys that cant seem to follow instructions.

The Dos Shell is pretty much what you want to use. what you have to do is this.

1) place the win95 install in the image file, and install it from there. (you would be stupid to do it this way).

2) or you can create a partition on your computer. install windows 95 onto it. then image the drive. copy the content to the c.img file on the dos folder, and modify the bat file to run windows.

they are NOT going to post windows 95 online for download, or this site would be a piracy site. If you really want to go through all the trouble to run windows on your psp then go for it. but other wise this is useless for the average psp user.

I’m sorry, I don’t want to be a hater or bust on anyone considered a “noob” here, but lets get real. If you don’t know how to cd to a directory, or what the fuck an exe file is then you clearly have no need for this. Hacks and mods for the sake of hacks and mods are one thing, but only if it means something to you. If you’ve never touched dos, or can’t handle an operating system that doesn’t have a mouse, then don’t bother with this.

That tutorial link is great – looking forward to getting Win ‘95 running on my PSP.

Quick note for all those asking where they can get Win ‘95 images: uh, duhhhh – it may no longer really be in use, but Windows ‘95 is technically still copyrighted software, and therefore cannot be freely distributed.

As for the whole “what do I do with C:>” thing – OMG! Talk about making me feel old! I was using DOS before I could even type!

Laughing I am, and with gusto.

Oh, and for those who are still interested (being an old thread), Bochs apparently works via the latest GTA eLoader exploit developed by Fanjita and Ditlew @ http://www.fanjita.org – which is how I intend to get my Win’95 installation running under my 2.5 firmware. Joshua, you might want to go have a look if you’re still stuck on that one…
