Gamedroid for "normal" Gameboy Games?

[Alarska]

Hi,

I just downloaded the GBA emulator Gamedroid. Since the real GBA could also play the old Gameboy Games (of the first Gameboy) like Tetris or Super Mario Land, I thought this would be true for the Gamedroid as well.

But I just downloaded Tetris and it doesn't work. Do you have any recommendations how to make it work. Or do you know an Emulator for Android that plays the old Games?

Thanks in advance
Alex
