RPCS3 FAQ

[Sincereless]

On a personal note, Why isn't there an universal emulator that can run through all the old consoles?

[Zekro]

Maybe because they have all different structures so making an universal one would be very hard.Also there is the bios problem with the ps2 emu and who knows what on the others

[Ekaseo]

pcsx2 is LLE-ed, so its slow? then if there were a HLE ps2 emu, would it be better? (of course bios would have to be emulated)

I believe that is what you meant. Faster doesn't mean better. And the answer is yes, it would be faster, but making an HLE PS2 emulator would be insane because of the PS2 hardware design. Almost impossible to achieve a decent accuracy I'd say, it'd never get good.

Also, just FWIW, HLEing makes the BIOS files unnecessary. You just emulate its behavior.

hm... its kind of interesting :/ so for rpcs3 , you dont know the PS3 hardware design (or maybe you do) and just chose HLE, cuz even now there isnt much info bout how the ps3 works, and if it would be impossible to make it with HLE, going to LLE would be very difficult... or d y certainly know that HLE has future for ps3 emulation?

[Runo]

Well actually there is info, otherwise it wouldn't be possible to make an emulator XD
There is not much public info out there, but DH (and the others) has good understanding of how the PS3 CPU works, that the scene gets by debugging and reverse engineering a console.

This should be very possible, there's nothing I can think about the Cell architecture that should make HLE'ing impracticable, and it is coming along nicely so far. We got the virtual CPU actually running stuff..

btw, what d you think bout this?:

[Runo]

I think he posted that in the wrong place
Seriously tough, I don't know what that is about, the devs will be able to determine if it is of any use
Sounds like a debug tool for the PS3, could be useful to get info on how some stuff work if that's the case.

Those are some of the .idc scripts used in PS3IDA, an adaptation of the PS3's code analysis for the IDA Pro disassembler written by KaKaRoTo ( https://github.com/kakaroto/ps3ida ). DH and me are already using this method to analyze and debug PS3's executables.

Nice
