That's odd. I replayed it under the following versions: MacMAME 36b4 running under MacOS 8.6 on an 8500 w/ G3 and a 3400c. xmame 36b3 under FreeBSD. I had to specify the ROM. DOS MAME 36b4, under Windows 98 (full screen). I also had to specify the ROM.(posted 9587 days ago)My FreeBSD and Windows 98 machine is an AMD K6-2-based PC (dual boot).
MacMAME ignores the configuration and high scores when it plays INPs. And I haven't had specific problems under DOS or xmame, either.
