one other rom to the m4apach set (which is where the dupe came from). I think m4apach might be another plasma game, but we don't have any
plasma roms for it. Also, fixed an issue with a set of sc5 games - From Haze (nw)
baseboard there (most of these ones actually run quite well apart from
some moaning about reels) This board used the AY8913, the mod4 board
didn't have that, so it's a logical split point. Also some more identification / tagging etc. of other sets. From Haze (nw)
(mpu4dealem.c) because it's a unique expansion, no point in having all
that stuff in the main state. The standard video board it's own state class too, and moved specifics to that, plus converted the scn2674 video chip to be a device (new files there too) again reducing the amount of junk in the base mpu4 state. From Haze (nw)
