Just make a backup of the font folder and that's it! You just have to copy and paste a couple of Files.. there's nothing that you going to fix. The results is similar to the Ge Patch, just try it.
It's work! Now the text are clear, sharper and bigger. Even the games looks like they takes advantage of this, i just trying with Ridge Racer PSP.
Thanks.
Ps. Sorry for my bad english..
