Oh yeah, I know what you mean. I know the Zuma clone and Bubble Blaster work, which is a good thing since I think from experience, those two are my favorites. Then again, Mother 3 doesn't work either on there.
If you really want to try it on actual hardware, you can get an EverdriveGBA, which is more powerful than the EZ Flash IV. This is me assuming you want to play the games on the original hardware.
