ROFL, once again you guys are amazingly funny. Maybe one for like 2 or 3 games but the same is true for the fps, and even on that note that's if homebrew on X360 ever happens. It will be impossible for certain games I am sure though because of the floating point computations that are processed on the SPE's; they are countlessly faster than any emulator could produce. This is my theoretical speculation on an PS3 emulator in general.
I definitely can say its impossible for PS3-FNR3 even, to run well (enough to play) on X360 (and vice versa), even though the game was "ported" to the PS3
Here we go again.... you can emulate any hardware regardless who is the manufacturer. It comes a huge cost of system resources. When comes multi-core, it helps emulation, but not that much. Today most of data are single process and only some are parallel process. That means the process need to wait for the result of previous of process in order to continue.
BLAH!!! come on guys the homebrew world on these systems hasnt even really taken off yet so the emulators are just a thing of dreams for now. ps3 will never emulate a 360 and vice versa and if some actually can write the code and execute it it will not not be fast enough to play. good enough for screenshots at best.
