Is this a possibility
i mean the gta 3 port, re3Hello.
Yes, played from the Gamecube Version via NINTENDONT on a Softmodded Wii.
Includes Cheats if you like.
No GTA 3 is a PS2 Game, Wii can't emulate PS2 games, even the PS1 struggles a lot
But Scarface runs on Wii.
There's a PPC port in the works on the Macrumours forum iirc, It's currently working on G4 and G5 chips albeit glitchy and buggy.
The Wii, having a CPU that closely resembles a G3 is probably to weak to run the game not to mention the 88 (?) MB of RAM that would struggle to load the models and textures.
Short answer: no probably not.
