Thanks for all your responses, I figured it out and was able to get the emulators working. The only one I'm having difficulty with is the SNEmulDS. Some games are difficult to configure accurate screen positions and stuff like that, but I'll keep tweeking it until I get it close.
I just bought an M3DS Real Perfect Bundle and I'm just getting used to it. I want to use some emulators (NES,SNES,GB,GBC) with roms. If someone can enlighten me on the procedures needed to use them properly, that would help me out alot.
