Hi Brucey,

I've found your very cool SID music playing algorithm for the Bass.dll and have a small problem. Most of the SIDs work fine but one file won't play.

"1942.sid" and "Defender_of_the_Crown.sid" play well while "Sacred_Armour_of_Antiriad.sid" doesn't play at all (no error message). I've taken them direct from the HVSID collection and they all play fine in SIDplayer2 and the only difference looks like 1942 uses 50Hz VBI (PAL) while Antiriad and DOTC uses both CIA (PAL).

Could you please have a look why it doesn't play? I need this for my C64 Retro launcher :-)

See this demo, I've included the two MODs and an example in the sidtest folder to play with (Keys 1,2,3): sidmods.zip

Hi. I've fixed the initialisation for that song.

Apologies for the delay.
