Introduction: How to Run Windows on a PSP!

About: I'm baaaack!

This instructable will teach you how to run Windows 95 on a PlayStation Portable! This change is not permanent; Instead it is a program within the PSP's Operating system that Emulates a x86 PC on the PSP.

Step 1: What You Will Need

Here is a list of things you will need:

-Slight computer knowledge
-256MB Memory Stick Duo (minimum)
-PlayStation Portable
-Good internet connection
-DOSbox 0.50 or above

Step 2: Download Necesarry Files

Here are the files (and links) you will need:

DOSbox 0.72 for the PSP
DOSBox config file
The Hard disk Images
The OS batch files (so you don't have to type them all)

Click here to find the following downloads:
Windows 95 disk image
Windows 3.1 disk image
DOSbox for PSP which includes the config files
Batch files for Windows

Step 3: Putting Folders and Files in the Right Places

This can get a little bit tricky, because if you do not get all the folders and files in the right spot then it won't work.
The most important one is the one called hdd which contains all of the Disk Images and Batch files.
Create a folder called hdd In the Root of the PSP's memory stick.
Copy(or move) the following files to the Folder hdd

w95.img - The Windows 95 Hard Disk image
win31.iso - The Windows 3.1 Image
osrun.bat (Starts either Windows 95 OR Windows3.1)
31run.bat (Opens Windows 3.1)
95run.bat (Boots up windows 95)


Once you have done that next you need to copy the DOSBox program for the PSP to the right folder.
If you have a PSP with Custom Firmware copy the DOSBox files (Eboot.pbp,DOSBOX.CONF,any .prx files and the DOSBox.patch file) to MSROOT:\PSP\GAME150\DOSBox(create that folder)

OR

If you have a PSP with OFW 1.5 Copy those files to MSROOT:\PSP\GAME\DOSBOX

Step 4: Finishing Touches!

The installation should now be complete, and you are ready to test it out. Exit USB mode on the PSP, and run DOSBox. If you get any errors, or you do not see DOSBox, then go back to the folders and files and make sure everything is where it should be. Sometimes it will freeze, just restart it.

Next, I will show you how to get Windows running. Whether it be 3.1, or 95.

This is the file that automatically runs on start up, with what each thing does:

[autoexec] --- This is found in the DOSBOX.CONFIG file
@ECHO off
cls --- Clears the screen
SYSOPT clock 333 --- Sets the psp to run at full speed
mount g ms0:/hdd --- Will mount the folder that we made that is called HDD as drive G:
imgmount c g:/w95.img -t hdd -fs fat -size 512,63,16, --- Mounts the Image as a drive in DOSBox
imgmount d g:/win31.iso -t iso --- Mounts the Image as a drive in DOSBox
mount m ms0:/MUSIC --- Mounts the Music Folder as drive M"
PAUSE --- Will say "Press any key to continue"
g: --- Switches to drive G:
osrun.bat --- Starts the OS Starter to Startup Windows

So Once it starts you press START or any button on the psp.
Then It will Show...
OS Starter 1.2
Next, You press START or any button Again.
Then it will ask you...
Do you want to start Windows 3.1?
Y is Left-Up(you press the Left Arrow the Up Arrow )
N is Circle-Triangle(You press The Circle button then The Triangle)
Then is says...
Press Y or N:
If you want to start Windows 3.1 You Press The LEFT Arrow then the UP Arrow.
If not You Press the Circle button And then The Triangle.
If you say no It will ask you if you want to start Windows 95
It will show...
Do you want to start Windows 95?
Y is Left-Up(you press the Left Arrow then the Up Arrow )
N is Circle-Triangle(You press The Circle button then The Triangle)
Press Y or N :
If you want to start Windows 95, Then you press The left arrow key Then The Up arrow Key On your PSP.
Then you have to wait about a Minute for it to start Windows 95(If your on a PSP Slim but if your on a PHAT it may take longer)
You don't need to login to Windows 95, Instead it will automatically start.(NOTE:If it does not load within 5 Minutes Close DOSBox and try again)

Windows should be running by now, if not, you most likely made a mistake with the directories and folders.

It is sometimes very slow, it may take a long time to start up, and may lag quite a bit.

Enjoy!
