If you remember those times, KOF91 by Moah was one of the few open-source alternatives to MUGEN, albeit not compatible with its data.<p>During those times I helped porting it to Linux together with Ric Leite. I remember being easy as it was Allegro.<p>I archived the sources here (from Sourceforge):<p><a href="https://github.com/dmacvicar/free-fighting-engine" rel="nofollow">https://github.com/dmacvicar/free-fighting-engine</a><p>You should be able to build it and run it on Linux (speed may be wrong).<p>I have tried a few times to revive the code, but it is a "everything is global" code-base.<p>I am currently testing an approach with Claude Code and Amazon Q, not very successful.
