Is shader caching "Really" necessary? Xenia does not use this!

Xenia "emulates" system that its practically pc in box, witch is process more like porting that real emulation and thats why games work well! Ps3 emulation is like space exploring comparing to that!  Dont whine, sit and wait to emulation get better, or if you want it faster be kind - donate

PS3 and Xbox 360 are using PowerPC CPUs. No one is a x86 System

I was going to say that, none of this emulators are "easy" to develop. In fact the original Xbox was never emulated (until now) for the complexity of the hardware. Is not as simple as, oh it has an Ndivia GPU and uses Directx! Must be easy!

But yeah, the guy is a total noob

On CPU side, both PS3 and X360 emulators have to use jit recompiles to convert PowerPC instructions to x86 instructions. But X360 runs a windows system, which means much easier to emulate the system APIs.
On GPU side, X360 uses Directx, which means shader bytecodes are almost the same as on PC.
None of PS3 and X360 are easy to emulate, but X360 is much easier to emulate compared with PS3
