PS2-Compatibility

Early PS3 FAT CECHA/COK-001 and CECHB/COK-001 : Full compatibility with GS+EE and Rambus memory. Later CECHC/COK-002 had instead of GS+EE a single GS and lacked the Rambus memory.

problematic, see Mathieulh quoted below
 The main issue here is that it's mostly not doable to emulate the GS efficiently with the rest
 of the hardware because the RSX is just not meant for this task and cannot emulate the GS on 
 its own while all the available SPUs and the PPU are already mostly fully used to emulate the 
 rest of the playstation 2 hardware, this explains why sony never could finish the ps2_softemu 
 and that it reached a stalling step.

 I honestly have no idea on how it would be possible to get over the ps3 hardware limitations to
 perform a full ps2 emulation without any of the ps2 hardware present on the console, one thing 
 for sure is that the emulator would have to be entirely rewritten and optimized like no other 
 ps3 software has been.
