Found an autotyper utility, and autotyped all my roms to MacMAME. This will help greatly with the arcade cabinet since i will not have to use the current MacMAME front end to open and play files. I will however only be able to play parent roms, not clones this way. For clones, the original MacMAME front end must be used, unless I feel like unmerging all of the ROMs (which I do not).

Also downloaded Zipit for use in ziping up merged romsets. For larger roms it may be easier just to get them off of mame.dk instead of Will and Tyris' site (which has been a bit slow as of late).
