Spartacus was written from scratch to avoid all the design errors I had made in Joker. (e.g. Joker had only partial move sorting). They share no code. Spartacus was set up to be variant friendly; it uses 24x10 mailbox board, and a more flexible encoding scheme for special moves. So it can play all variants with the same engine, just re-initializing its piece-square tables. (Joker does not have PST, just a centralization table shared by P ,B ,N and end-game K.) Joker uses SEE to sort captures, Spartacus uses BLIND. Spartacus has an 'inverted' move generator for captures, using 0x88 methods to generate them in MVV order, so it can do staged move generation. It is designed to work from an incrementally updated attack table to speed this up, but that does not work yet, so it is currently disabled. Spartacus has a Pawn hash and a material table, more aggressive LMR, but poorer evaluation (especially King Safety).
