I've kicked around the idea of setting up a forum specifically for Dreamcast game modding. Particularly Half-Life. There was a site awhile ago called dcfan.ru that had A LOT of documentation on Half-Life modding. It would be really cool to get something like that going here
There is one missing section. Why not keep New Releases/Homebrew/Emulation for new applications and game developments for Dreamcast, but have "Modifications" or "Game Modding" section with the purpose of modifying existing applications and games
