I use version mame 0.186.
I did this steps.
Downloaded lateste mame version from oficil site.
Went to rom site and downloaded single roms games, like pac-man, cabal, the punisher.
games like punisher and cadillacs give missing rom message.
If i install older version of mame, like 0.161 the same punisher and cadillacs will work.
My question is, is it worth updating mame to older version? cause some roms will not work.
