+/****************************************************************************
+ The Toaplan 2 hardware with V25+ secondary CPU controls the sound through
+ to a YM2151 and OKI M6295 on some boards. Here we just interperet some of
+ commands sent to the V25+, directly onto the OKI M6295
+
+ These tables convert commands sent from the main CPU, into sample numbers
+ played back by the sound processor.
+ The ADPCM ROMs contain intrument samples which are sequenced by the
+ sound processor to create some of the backing tracks. This is beyond the
+ scope of this playback file. Time would be better spent elsewhere.
