Hooooboy Spudster, more problemos....
Found MAME for both PC (what I believe is the PC version .0123s) and for PPC (what you have called pocketcultmame 0.4a). Downloads give a htm file as a read_me that links to a page with free roms. Now, you put these files in the MAME rom folder on the pc and they show up on the MAME intro screen as selectable. Problem is, they all give an error that needed files are missing
??? Some of these files have *.bin extention, some have nonsense extentions (ie: .7b, .10a) but none have a rom or chd extention that MAME says it needs to run them....
What did I miss here:o ?
