You mean a good P2 6502 emulation. It's on my to do list.
Yes, that's what I meant. (relatedly, RSIDs are the ones that play samples and stuff and therefore need accurate timing emulation)
Right now I am attempting to pair it on the P2 with real vintage hardware, The Tandy Color Computer 3.
I will put SIDcog on ice for now and continue my SID emulation efforts on the P2 as a part of the Crescendo project! I MAY put out one last official version with all the known fixes discussed above.
