Is it possible...(GBA related)

[Spike Spiegel]

...to get the Arcade Game on Battle Nexus GBA?

Nah it's not possible, but we can dream.
I did get Snes Turtles in Time working on a GBA, it was with a Flash card and software you use with your PC, it was very slow though and no sound, but all the original nes games work perfectly.
