A ccminer v0.6 source code release was made, adding myriad-groestl (the table based groestl implementation like in the SPH library) and a jackpotcoin implementation.
My jackpotcoin implementation computes only the keccak portion of the JHA hashing algorithm and throws away 7 out of 8 hashes. This is way faster than computing the remaining rounds for the hashes that I am throwing away

jackpot is now a CUDA coin it seems, and it is fit for solo mining. Quick, the AMD miners are going to catch up soon.
