I'm using my R4 with an ADATA 2GB MicroSD and the final English 1.06 firmware, yet Diddy Kong Racing DS isn't working for me. It loads, shows the initial splash screen (with warning that play may change while online,) fades to black, and never goes anywhere from there. No other games (except Castlevania: PoR & Tony Hawk Downhill Jam) have given me any trouble at all. Anyone have any hints, tips, recommendations, or, better yet, solutions?
