Oh, I've got the ROM's extracted - I've got several other pre-release versions of various HuCard games (also dumped from EPROMS) - this is the only one that was unreleased (as a HuCard at least).
Problem is, I was never able to get the extracted ROM's (for CC) to work in any emulator, regardless of how I combined them. I'm sure somebody could get them working, but I had no luck.
I've not distributed any of what I got because it was packed away, and also (for CC), it would obviously impact the value of the proto board...
