Well, I knew homebrew was an option, but I thought you were saying that SoMI was actually released on DS at some point. I've actually got ScummVM on my laptop (with all the games mentioned above, plus a few others). Are you sure that Monkey Island 3 won't run on the DS? I know Grim Fandango and Monkey Island 4 won't (they were programmed with LUA, not SCUMM), but Monkey Island 3 runs just fine on ScummVM. Does it have something to do with the 3D rendering in the game, or simply the fact that the files themselves are so large?
