Not all SID replacements will work correctly with ReSeed.

This is because for technical reasons the SID is clocked at a lower frequency than what it gets on the C64 (~886 vs ~985 kHz). Some SID replacements do not use this clock signal at all and just assume C64 frequency (I guess), leading to incorrect data transfers. This is the case with the SwinSID, for instance (but this might change now that Daniel Mantione has reconstructed the firmware sources, great job!).

On the contrary, the ARMSID is confirmed to be working well (thanks root42!).

There is also an undergoing effort in order to get the SIDkick working which, being open source, will be my strongest recommendation.
