Yea the romscan for Kawa-X SE takes less than a second cause theres only a few roms (those are the only roms I have in a seperate folder), but the rest of my MAME, CPS1/2, NES, Genesis, SNES, blah blah etc are in one shared common rom directory. And to clarify Im not asking how to change the name of the game shown on the dashboard, Im asking how to change the internal titleid which determines the directory in which files are saved. For Kawa-x its '0000FA7E'
