I was thinking the last release of v37, why 36?
What Elvis said, but . . .
R36B12 is the magic pre-alpha blending release, especially important for Battlezone and less for Astdelux (I still use this for bzone with an XP2800 Barton).
R37B15 is the first windows version with hardware stretching and the last truly working System 16 build.
Everyone needs to get over this notion of "I need to just install this version of MAME on my cabinet . . .
Put all your roms in one folder. Install MAME R36B12, R37B15, 0.55 or so, and 0.90. Play a few games in all of them, see which one gives you decent performance. Use this as your primary build. Use the older builds for the few games that play noticeably poorly in the primary build. Use the newer builds for games that weren't emulated in the primary build - they will be choppy or sluggish, but they'll work. Use your frontend to select which Mame build gets used for each game.
You don't have to give up anything . . . .
I wish I knew why more people can't embrace this concept!!!
