Summary 05284: exprraid and clones: YM3526 has incorrect frequency
Description The music plays at the wrong speed in MAME. If you listen carefully to the music playing on the horse stage at the end of the following video, you can make out the fact it runs more slowly on the pcb. At the moment the speed is listed as 3.6mhz in MAME - it should be 3mhz to be the same as the original game. This also ties in with other Data East games of the era which ran the chip at 3mhz.
