you can call me that but I wanna know some stuff !
Is there any good emulator that can run Commercial games ? and what kinda of PC I need to do so ...
Been out of emulatoin world for very long time , so I need to catch up

Dolphin, but you need a very fast system for it.

Even so, Dolphin is highly experimental and a far cry from perfect.

I see , so its at the same lvl as Pcsx2 !
I think we need to see Maybe Due 5 Core before playing next generation of emulators XD

Most emulators will not take any advantage of multiple core processors, that I know of. But my knowledge of emus is quite limited. The emu still has many graphic and instruction glitches so even a super pc will still have troubles.

From what I've heard, so games like Legend of Zelda: Wind Waker are quite playable (I don't think from start to finish; there are lots of bugs that raise their ugly heads at the most inappropriate times) in the latest SVN builds. Only dual core machines apply.

*Sigh* an d I thought I could play Fire emblem T_T

IIRC, Dolphin can run FE with some graphics bugs, like you need a projection hack to see the menu stuff.
