gba for xbox? 4 player?

i like to play some gba games on the xbox
but i need a emulator that could let me link up to 4 player on gba games all on my tv

so how can i get 4 player on 1 box?

 

i dont know if u can do that....

 

oh well that takes the fun out gba on xbox lol
i think it should be added there are 4 control slots and the screen could be made into 4 like halo on 4 player etc
and all load a sav file from like there mb stick which i think is G on my xbox when i pulg it in files appear when not pluged in nothing in it

 

well even with the emulators on the pc you need 4 emulators open to play a 4 player game on 1 pc...

 

there is one on the pc were you just need 1 open and it can do up to 4 player so i know its possable
