Get ClrMamePro, or that linux utility (name?).Get MAME 0.78 rom collection and MAME 0.139 collection.I think what we ultimately need is more of a checklist or recipe. Final thought on the RetroPie docs: I've contributed to docs before and they're as good as any out there on the subect, but this process is kind of convoluted if you are trying to explain it in a general way. When there is a shortcoming with those docs, I'd go so far as to say we fix them first before writing new things here. Whenever possible, we're going to defer to the RetroPie docs at This issue will track our notes in anticipation of adding some short comments to the README or other docs helping users figure out how to rebuild their roms for this core.
