I just got a reloaded mk2 board and installed it - all looks good! I installed 6581 and 8580 SID chips.
However, despite setting the following settings, MSSIAH won't use the 2nd SID:
- Stereo SID set to $DE00 (this is what MSSIAH uses)
- SID 1 and 2 set to mono (stereo L/R mode also does not work)
I swapped SIDs thinking one may be broken - nope, same issue. SID 1 always plays, SID 2 does not.
The board detects both SID chips.
