so we can test all combinations of few bytes (the bytes involved in the patch) until a correctly encrypted output is found This won't work, because if you change one byte, the bytes after this byte have to be changed, too, to reproduce the same unencrypted bytes as before. Assuming a 64 byte block ...

I was not so clear... I don't want to use unencrypted prx, I was thinking about patch the unencrypted and see if it works, using an emulator, then find (by brute forcing bytes) to make an "encrypted" patch to the prx. So we can have a correctly encrypted patched prx, we don't known the pri...

An idea about kernel mode for 2.0

My idea could be totally wrong, but I want to expose it so I can get comments about it. Step 1 find a way to patch game_plugin or other involved prx to make load unencrypted eboots. This can be eventually tested using a firmware emulator. Step 2 prx are encrypted and then compressed or vice-versa? a...

the version in sid is a 4.0.2 with some patches from cvs of 4.0.3, it worked also with 4.0.2, but I suppose the gcc on debian has a lot of patches to avoid breaking compilation on multiple architectures (fbts) that can make toolchain work on gcc 4.

SDL_ttf & pspgl

Since pspgl doesn't supports all of opengl api, sdl_ttf configure incorrectly detects opengl support but compilation fails since pspsgl misses some function. This patch solves the problem, and it will activate GL support in SDL_ttf when pspgl will implement these functions: Index: configure....

I've also noticed this nightmare playing with the order of linked libraries, but I never seen this behaviour e.g. on linux, I've seen similar problems in the solaris linker, there is no way to avoid it? psp linked libs are likely to easly increase in number and this problem can be very annoying
