I'm taking care of some support for HuC currently. It isn't very fast because speed comes from hand optimizing for the CPU on the PCE. Let me know if you need anything specific though (I've got a bit of experience with the ASM side of the Clib). Plus, Nodt knows his way around HuC in general probably better than anyone.
If you got a chance, come over to #utopiasoft on efnet irc.
