I've heard this is possible, among other things on the DS, so I researched it, and came up with this page:
http://www.cs.utah.edu/~tew/nesDS/
All it has is a ZIP file with some executables and BIN files.
Point is, does anybody have any clue as how to go about doing this? Let's say I have some NES Roms on my computer...how would I port them to my DS and play them that way?
Man I feel like such a n00b at these things. I may as well put my DS to good use.
