Yep.
obeybrew.com is to be
the definitive guide to all things PCE homebrew. Currently, I'm working on documenting all of HuC, including previously-undocumented features. It will also have lots of example source code, tutorials, and other such goodies. Arkhan will be contributing as well, not the least of which will be some documentation and whatnot on MML. The site uses mediawiki, but I am only allowing authorized people to make changes. Proper documentation is hard enough without having some joker go in and muck it all up to be "funny".
Also, PC-FX homebrew is on the horizon. The author of mednafen had been working on a toolchain for quite some time, but I guess gave it up due to overall lack of interest. Well, it was picked up by someone else (trap15) and has evolved into a completely working toolchain. It's now possible to develop new PC-FX games! The library for the PC-FX is still somewhat low-level, but I will be working on high-level functionality to bring it up to the coder-friendliness of HuC (or better, preferably). The toolchain is designed for a Unix environment, but on ObeyBrew, I document a way to get it working with cygwin for Windows users.
Here's one of trap15's examples (fxbmp.c), built entirely on my Windows system:
Not too impressive just yet of course, but it does show that yes, legitimate PC-FX homebrew has finally become a reality and can only grow from here.
