Nope, on my 1.42ghz mac mini even stuff like Aladdin isnt quite perfect (although its pretty close). Having said that though Ive not spend much time fine tuning euae config, so there's probably a little more juice that can be squeezed. From my experiences with it on othr systems, and the difference a bit of tuning can make Id hazzard a guess it could be maybe 10-20% either side of a stock a1200 without fastram (depending on the game).
Big difference between a similarly specced G4 vs. an x86 system with euae (favoring x86 of course). Hopefully this will change eventually, but if the "progress" reported thus far for the ppc jit 68k emulator is anything to go by I wouldnt hold my breath unfortunately.
