First Release.

First release of a native OPL2 tracker for the RP6502.

How to get started:

1. Upload RPTracker.rp6502 and DEMO.RPT to your PicoComputer
2. Ctrl-O to get the load-prompt and type DEMO.RPT to load a demo-track
3. hit F8 to place the Tracker in Song mode
4. hit F6 to play the Song
5. hit F7 to stop (Hint: you can always use F7 to kill any hanging notes)

This is just the start, but it's something to show off the new OPL2 capabilities!
Some future todos:

• Add more steps to the sequencer
• better global / cell edit functions
• gamepad support for a DJ mode
• effects such as an Arpeggio
• maybe mouse support?
