Sorry if this has been asked before, but will it work with Scrypt-Jane, such as YaCoin?
Thanks,

Been a bit busy, I will ask my engineer to be sure. But looking at what jane is (Chacha) it
probably would yes.
Negative. The logic would be radically different between a Litecoin-oriented Salsa20/8 (1024,1,1) implementation and a YACoin-oriented ChaCha20/8 (N,1,1) + Keccak512 implementation. There is very little similarity between the scrypt variant used in Litecoin and the scrypt variant used in YACoin. Additionally, YACoin uses variable N while Litecoin has fixed N=1024. For YACoin, N is currently 32768, and will change to 65536 on 31 May 2014. Details on the variable N schedule can be found in my post here:
https://bitcointalk.org/index.php?topic=206577.msg2162620#msg2162620When YACoin launched at N=32, I adapted 4 of our earlier FPGA LTC prototypes (populated with XC7A200T's and a pile of DDR3) to YACoin instead. It was real easy pickings at N=32. At N=64, not so much. At N=128, I stopped and moved back to a different more efficient hardware solution for YACoin mining.
Variable N would make ASIC implementation a real bitch, since you can't optimize the mixing function's logic for a specific value of N like you can with Salsa20/8 (1024,1,1).
