No$gba multiplayer?

[Desiboy]

I started playing no$gba some weeks ago. I play bomberman and i like its battle mode. i also play mario kart and mario party. The problem is that i want to play with a friend on same pc. I want to play bomberman 2 player. i have the bios, but when i select the cartridge it always says "The rom image has crashed. if i try to link 2 windows without bios, they did not find each other. What to do? Is there any nds game in no$gba i can play multiplayer?
