Yo tmbinc ! Nice to see you joining from Gamecube development to PSP development ... Finding overflows in the Wipeout browser is not the time worth for doing research. I personally think it's easier to find an overflow in the build in media player routines (jpeg viewer, mp3 player, mp4 player etc.) ...

Normally if you have a "bad flash" and sent the psp back to a repair center they're using a so called "JTAG" interface. This interface is a 5 wire connection cable, and with it you have full system access via the cpu to the ram/rom/flashes and you're able to re-program the flashe...

Re: Random blah, wondering on 1.50 - 1.51 hole fills

Just wondering, whats the likelyhood that once the 1.51 update comes it can be compared to the 1.50 update to find the holes they supposedly fixed? There's no way to compare 1.50 with 1.51 until you have decrypted both bios files ... AES encryption leaves no space for hexedit compare games ... And ...

In a good encryption algo you just change 1 bit in the source file and the destination file differs completely. AES is such kind of encryption. This is not a "do a xor / ror " over the data and gotcha ... AES is hacking/cracking proof. If no one spents alot of $$$ money $$$ to hack the cus...

Cracking or Brute Forcing AES ist very easy !

You just need some time, that's all.

We're talking about 1-200 thousand years.

If you're intrested in decrypting stuff / analyzing data / doing statistics then have a look at this:

It has also the possibility to AES decrypt (and brute force *lol*) psp stuff ..

@pushpin, that's interesting & it's good to see that developers are minimizing UMD access. Ridge Racers is completely stored in ram ! When you're playing Ridge Racers, you can remove the UMD directly after the race start. The game asks you to to quit, but if you deny to quit, you can race the c...
