#24 OPL-L/MSX tracker support

[Anonymous]

The Yamaha Y8950 and YM2413 used in the MSX hardware are basically OPL1 and a scaled-down OPL2 respectively, so trackers designed for MSX should have no trouble on playing music in OPL2 hardware. Besides, there are already trackers for MSX[1]. The only issue remain is the digitized sample playback, which would work by using wavetable feature of OPL4 (if the OPL4 emulation is done).
