I want to run this game on emu is possible or it isnt?

It's possible to run it on emulator but your runs won't be allowed on the leaderboards.

and my last question witch version is better gamecube or metroid prime tryology

Gamecube. Trilogy sucks. Make sure you have 0-00 version.

Also it's best to play the Gamecube version on the Wii because playing on a Gamecube can cause the game to crash in a few places.
