I've seen threads on how to install this, and since me and a friend made it, I want to see people use it.
First off, when you download it from this site, it will have two .rar's in it. It will have the slow version, and the fast version.
Mouse moves slower but teh graphics are very smooth
Mouse moves fast and smooth, but edges on graphics are rough.
So at this point, you just pick a version. Once you pick a version, inside will be two folders. Put these two folders in your GAME folder on your PSP. Once they are in your game folder, like any other homebrew, grab your PSP.
Then just lauch it from the memory stick in the GAME section of your PSP. Have fun, Virtual Escape OWNS!
