0x00-0x5F=Note value pulled from chart. 0x60-0x7F=Opcodes without tramping into $80 range? Format: #%1100.00BB=Whole byte bit value to follow. Single value. May be scrapped and the opcode #%1101.BBBB will be used only. #%1101.BBBB=Array of bytes to follow opcode that each go into a register, for changing 2-3 or so registers at a time with minimal opcodes. 0x80-0xFF=Bit set for half bytes of each register. Format: #%1HBB.VVVV H=High value byte to change. BB=Byte to change inside the buffer, choose between 4 bytes. VVVV=Value of the bits to set in the byte.
