I agree with Garett it's just about the same with translating console games as you'll hit any number of compression/encryption schemes.
The tools are pretty nice on the PC as you have both IDA Pro (free edition available) and Ollydbg (my preferred tool). The only gotcha you'll find though is when trying to debug a fullscreen game as that can cause any number of issues due to trying to alt tab out of a frozen process which you can't do (and if I'm wrong please tell me
) Most times you can get away with a directx windower but there's all kinds of flavors due to the various directx versions.
Couldn't answer about jrpgs as I mainly focus on visual novel games but feel free to ask me anything about pc hacking.
Also Garrett, I think that title was stolen by 5bp for Steins;Gate 8bit as that game has no less then at least 20 different ways to calculate a XOR key for decryption based on the checksum produced when zipping up the chunks (arguably it's 0x7F possibilities but luckily when using the last byte of a checksum it's not that unique). Ugh (Pretty fun figuring it out actually
) At least for Falcom it was just a modified LZSS scheme that I've noticed so far.
