I hope the external db can be a CM dat.
Can a CM dat contain INES / NES 2.0 / UNIF info for managing NES ROMs? Because of the issues specific to NES, you almost need a separate ROM tool for this console (like NSRT is for Super NES). I'd love a cross-platform NES-specific ROM tool that can scan ROMs, fix common bad dumps (like the infamous SMB pirate dump), convert between INES, NES 2.0, and UNIF, rename and sort ROMs, etc. Anyone here willing to take on such a project?
