Re: SID dump file format

the player just needs a minor change: if bit 7 of channel-delta-flags (bit 4 of filter-delta-flags) is set, then it processes another set of delta-flags plus register values for the current channel or filter. in the dumper, i implemented some basic end-of-tune-detection... dumper+player: https://www...

Re: SID dump file format

Re: SID dump file format

found the problem why last ninja 2 does fade out: the gate bit gets written twice within the same frame. i.e. noteOn and noteOff triggered. so reading/playing only the register state at the end of a frame will not work... will add a flag which tells the player, that another set of register values fo...
