It's now been about 5 days and I have yet to successfully convert a MAME/NeoGeo/Etc. files to actually work on my DS. I've tried typing cmd, dragging NeoDsConvert.exe into the window, adding -bios6/-bios8 mslug to the end, tried 3 different bios file downloads, everything I can think of. I give up. There's nothing else I can use to convert these files?
