EBOOT.BIN Decryption

[Hykem]

However, the good news is that I found out what was wrong with "Dissidia", but I'll have to temporarily revert all those commits to get the CryptoEngine working again...

Thanks for the good news
Then, one more question....
After playing for 2 hours, Java.exe *32 consumes a huge amount of memory... about 1.869.540 K ... In the end, it freezes with a log stating that I've run out of memory. Is there any chance of improving JPCSP so that it will take less memory in the long run ?

Hmm, that's odd. A Java application should never consume that much in a long run. I've already managed to get JPCSP running for about 5 hours with a 3D heavy application and it never did that...
Could you please post your PC specs?

Oh, by the way, as of r2038, it should now be possible to decrypt Dissidia on the fly. It seems this game uses an unknown MIPS relocation that has been adapted by the internal PSP's processor, Allegrex.
Apparently, index 255/0xFF is actually a stop code.

@Kyotoo: This may also represent a solution for K-ON!, Kyotoo.
