[quote]What is this?

Yes, it's true. I've managed to run Windows 95 and Linux on the PSP. I've done it by porting the excellent open source x86 emulator Bochs.

Windows 95 actually runs quite well but don't expect it to be a speed demon. It takes about 10 minutes to boot but afterwards it's pretty usable. I was able to do things like: open "My computer" and browse the virtual hard drive, complete a whole game of Minesweeper and run various other applications. Now you too can get your Minesweeper fix on the go

I've also tested DLX Linux which comes pre-packaged with Bochs and it works just fine. However, I couldn't do much with it because there's no keyboard support. If you want to do your word processing on it then wait until keyboard support is implemented (though I doubt it will be any fun using the joystick).

In windows, mouse handling is extremely difficult. I suspect it has something to do with the "boost" feature windows has. Once you get the mouse moving it will keep moving in that direction even when you're trying to move to a different direction. The solution is to counter the movement by moving to the opposite direction. It's sort of like trying to push the mouse the other way in order to stop it.

Future improvements

- I've used a simple software rescaling algorithm so the entire screen will fit into the tiny 480x272. This of course takes a lot of CPU time and slows everything down quite a bit. It is possible to rescale the screen using the built in 3D hardware acceleration and I will get on it soon.

- The analog joystick should be used for mouse support.

- Some sort of keyboard input should be implemented although you can use the windows virtual keyboard right now.
