Summary	09282: acrobatmbl, hachamfb2, macrossbl, strahljbl: Wrong OPL2 clock
Description	Some of "bootleg with Raiden sounds" sets has wrong clock, so it became different music from original PCB. tdragonb, tdragonb3, mustangb, mustangb2 have correct clock. They have 3.579545 Mhz of YM3812. and it's same as original Raiden sets. (raiden and clones) acrobatmbl, hachamfb2, macrossbl have 4 Mhz of YM3812 in MAME, so their music is faster than PCB. strahljbl has 3 Mhz of YM3812 in MAME, so its music is slower.
