M1 0.7.7u2 is now available. Get the Win32 version here, and the Linux binaries here. This time the Linux archive includes binaries for x86, x86-64, and PPC architectures (the PPC binary works on the PlayStation 3). If you are not on x86 and are reporting a problem, please mention that fact.

The official board is right here – read the changelist there.

UPDATE AGAIN (Feb. 6): Here is a revised m1.xml file that fixes many issues vs. current MAME and adds many games, including over a dozen new pinballs. Note that pnyaa will not play without a revised executable, but I’m not quite ready to rebuild all 4 versions just for that 🙂
