Last time I did a full update was in the .dk days. No need to enter the pokerom stage, especially when these days all the 'new' sites haven't been updated since MAME 0.108 or something, or are in multiple gigabyte solid archived torrents with no way of updating the odd set without downloading 300GB to get two 512 byte PROMs added to blahblah.zip for example (almost like trying to get something to run in Linux, dependency issue after dependency issue!).
