standard sony CRC poly?

Post by splynncryth »

I was messing around with a save game and it looks like it has a 32 bit CRC attached to it. I say this because there is a 4 byte piece of data thet follows everything I can make sence of, it changes drastically with even a single bit change, and being that it's 32 bits, it would fit in nicly with being the remainder generated by a 32 bit CRC operation. I'm baffled on how to get the polynomial used for the CRC generation, and I haven't learned enough MIPs ASM (let alone PS2) that I'd feel comfortable delving into the game's code. I was wondering if anyone knew if there is a standard polynomial used for the PS2 off the top of their heads.

Read the forum rules, there's no save game hacking here.
