ApprenticeMinusDS is a Sega Master System/GameGear Emulator for the Nintendo DS. At first this was only made to debug the ARM assembler Z80 core used in jEnesisDS, but with a little work put into it, this can actually be used to play some games now.

ApprenticeMinusDS 0.4.0 (Neo version) was ranked 1st in the NEO Summer Coding Compo 2008.
