This game wont load!

Ok i downloaded one of my favorite homebrew games for gba ,2004mbit Compo Game months ago. And i have just been emulating it on my pc and i think its an awsome game. And i was looking forward to playing it on my ds with my Supercard Lite and Superkey , but when i try to boot it the beginning goes good untill it gets to the main menu and the screen blinks and flashes and stuff.I have patched the game with the Supercard Magic Homebrew Converter thingy and I also tried the official supercard one both times the game would show the intro then flash and get messed. I dont know if this game isnt supported or what but if anyone could help me get it to load it would be greatly appreciated.

If you want to download and try it you can get it here

do you have a supercard rumble

No a regular Supercard Lite
