Most of the games I tried to use were games I used to play in dos,
Bio Menace loads but then comes up with an opcode error
the oldest game I could find [Roomz] didn't work either
Keen4 works quite well though and Duke Nukem does too
I really thought that I would never see DOS on the DS...
Things that don't seem to work:
Prince of Persia 4d
Sim City 2000
Monster Bash 1
Doom
Hocus Pocus
Wolfenstine 3D
WordHunt
StoryMOM
MegaMan x
Lemmings War
Hugo's House of Horrors
JetPack
I like that games can be fixed after the fact, hate that it's being abused via beta tests... And DLC... I was a 7800 owner back in the day and loved Impossible Mission, turns out I couldn't beat it because it was actually impossible lol
