I have been running mame32 for a couple of years but they do not do the in between versions anymore (ver78 but not 78.1 or 78.2 etc....)whenever there is a game i want to play that gets fixed in a in between version (like hot rod) I put in mame plus and point it to my main rom folder. but the dats for mame plus are differnt. Is there a way to combine the two dats so I can run both versions out of the same folders and have all the right roms? I know I would have some unneeded files for each but I have the space.
