I believe I'm selecting "Load Content" and then navigating to the Folder I created for MAME Roms. I'll take another look on there and see if there's an option to load anything else
Thank you! I'll be sure to leave all of my downloaded roms completely intact with their original file names.
Geez, I forgot how annoying MAME emulation was -
a. Different romsets depending on the version of MAME being used.
b. Some games need a BIOS file, some don't.
c. Parent/Child Roms.
To be fair, I've only actually tried (3) games with no luck - Mortal Kombat I, Super Street Fighter II, and The Simpsons 4-Player. I also tried deleting RetroArch's CFG files with no luck. Each time I get either a DSI Exception (MAME 2003) or just an empty black screen (MAME 2003 Midway) with all 3 ROMS.
Any other ideas?

**** UPDATE: It works! I tried downloading a new rom (TMNT: Turtles in Time) from a different source and it booted up fine. Guess it just took some trial and error
