there is also BlueSCSI v2, same as zulu. Hard to figure out who is leading and who is just a fork.

Its not the same, if it works then thp successfully narrowed down relevant registers. You can try it on C610 to make sure it doesnt break other AD1980 implementations. All the emulation issues are down to SBEMU engine, last update was 7 months ago so it looks like work stalled.
