Kirby is also another good game to get running. It does not do a lot of fancy stuff, if I recall. The only thing is that it requires LZ77 decompression (SWI 0x12) and Huffman decompression (SWI 0x13). Huffman decompression is only used for the graphics shown at the pause screen (the ones that describe Kirby's abilities). Super Mario Advance 4 might need EEPROM support to boot, I'm not sure. Super Mario Advance (the 1st one) needs it to boot properly.
