I checked around google and in the FAQ but did not see my problem.
I'm running the latest MAME for OS X on 10.5.8 and it used to work just fine a few months ago, but for the past several months I can't get the application to open without it crashing.
I've tried reinstalling MAME several times with no improvements and last night tried different versions of MAME OS X in case it was a problem with .135 or something.
If it's helpful I can copy paste the crash report thing from when it crashes on here.
MAME OS X is no longer an active project. That said, usually when it crashed it was due to the presence of add-on audio hardware such as a ProTools or M-Audio setup. If you have anything of that nature, try disconnecting it and see if MAME OS X will start up.
Hmm! Well it doesn't seem to be helping when I disconnected and restarted the comp. I realize it's not longer an active project... is there another program I can use instead?
