Can't find any good resource on this problem... I have an eMac with 256MB RAM and 10Gigs free HD space and OS 10.3
I DL Macmame and when I double click it, it appears for 1 second in my icon dock at the bottom and then closes. The docs don't point to any incompatibility with my setup and as far as I can tell even if I didn't have any roms or even have them located in the proper place, MacMAME should at least open and stay open.
I read another forum issue on this and someone said something about authentication logins... well I've rebooted(just in case) and besides, his symptoms were different as he could open the program.... I can't.
Started out using an Amiga for years back in the day, PC's too(heck used MAME for DOS and windows so I know what is needed generally), and this is my GF's Mac but it's not hard to use and I can follow any direction no matter how technical... but in this case I'm a bit miffed because it really should just work.
