Dave Shadoff?
Who do you think said "It's not worth fixing if no one is using it."
lol. I ran all of the problems with HuC by them on IRC and was met with apathy: The recurring PCE Dev theme.
I think the entire original "TGHack" crew is about done with doing anything. They had their glory days back in 1996-2005ish, and now have moved onto other things. They still float around/post (kind of)/chat on IRC...but they aren't doing anything. They didn't seem too interested in doing anything either. Maybe one day they will again.
The one guy is a phantom (Jens). He just disappeared. I asked where he went and was given a "don't ask" response, implying there is a grudge or some lingering loldrama. *shrug*. He would have been great to prod for info when Squirrel was a new idea. Oh well.
I myself learned the basics of game programming from a few books for Windows (One for 2D, one for 3D, one for DirectX and one for RPG design), screwing with allegro (tons of open source crap!), messing with RPG Makers (Verge, RPGMaker2000399024), screwing with QBASIC games, and doing crap on the C64 (type-ins, experimenting...).
Those goony old books for 8 bit computers really do a good job of explaining things about games that you don't get told anymore. Crazy.
