I can put GB, GBC, GBA, most GBA homebrew, and all NDS homebrew on my Supercard Lite. But for some reason when I load a retail game (.nds/.dsq/.dsi) it will load regularly but then two white screens appear. I updated my software and the hardware's firmware but it still happens. I read that newer games tend to do that but even my old NDS games wont work!!!! ie Metroid Prime Hunters is what I'm using to test it.
