| colspan="5" | problematic, see Mathieulh quoted below
<pre>
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.
