The PS2 hardware was then further removed all-together from later models (including the slims), I am not sure where the full software emulation came about but no PS3 officially supported it, the compatibility is very poor, it appears they reached a stalling point with the GPU emulator which may have hit the upper bounds of the PS3's capabilities and thus was not implemented as a feature on these consoles.
Is this an observation of the Cobra's performance, or the general state of PS2 emulation?
To my knowledge no PS3s, apart from those sold by Sony as having backward compatibility, have attained backward compatibility as the result of hacking. The exception to this would be the Cobra dongle which, purportedly, allows for PS2 play on previously non-BC systems.
So when you say "poorly" are saying you referring to the Cobra's performance in emulating PS2 games?
