RPCS3 FAQ

Second off, and I'll assume I'm not asking this in the wrong section, ya know, faq support and all, but will running RCPS3 require my PS3 to have CFW or anything? I've read a few posts mentioning it, but is CFW a requirement, like I might need to grab some files or something?

Depends on the game. Some programs load font files, you could dump the real ones from the PS3 OS, or just use any font and rename. Really, the only other thing I can think of is that some games load are \dev_flash\sys\external\flashMP3.PIC and flashATRAC.pic which I guess are codec files or something like that. I think you need custom firmware to get these, but there might be other ways...

Still, 9/10 games don't load any system files at all it seems.

And like Ekaseo said, this is a HLE emulator, you don't need a full BIOS dump or anything like that.
