im trying to get these emulators to work : SNEmulDS, nesDS, and lameboy. before i put away my ds in a box, it was able to get these emulators to work. i just had to place the .nds file somewhere, run it on the r4, and find the game files in the correct directory. i previously reformatted my micro-sd card, but was able to back up my games. now when i try to run the emulators, it wont work. i searched and downloaded the latest versions. the emulators seem to run,but i am unable to run the games itself. as for SNEmulDS, i have all my roms in the SNES folder in the directory, but it says it doesnt see it. edit: i got nesDS and lameboy to work. i just need to figure out how to get SNEmulDS to work.
Are you sure you uncompressed the files? Most roms you download are zipped or rared. The emulators cant read the compressed files.
