FMHQ community member here. I wish Enterbrain would release a new one already, but it seems like RPGMaker is the favorite child. The current (hacked) version of FM2002 is so uncompatible with Windows. Keeps fucking crashing whenever I wanted to load my sprites. Not to mention the limitations (256 colors, wav sounds)
A member of FMHQ made FIghter Creator which is kind of like FM2002 but with png support and mp3 sound file compatibility but the program itself has very little documentation. However, the thing I like about FM is how easy it is to load sprites. Compared to MUGEN when it came out, it was such a breeze.
There used to be many FM communities online but the only one living now is a sleepy forum and a Discord. In Japan there are still Doujin games made with Mugen but they never had any contact with the western FM community
