Yeah for better or worse something I discovered was that the number of projects that fit the standard pattern of projects derived from the original's source code is actually pretty small, and the reverse engineering efforts are more common than I thought.
Better! However, just including the filter could have solved this and other problems. Only having it on the main page was lost on me when initially viewing. Page on but let me filter. Also when clicking on a page, trigger a scroll to top. There were a couple times where I clicked on a pagination page number and it looked like nothing happened but the above content changed. Snappy but send me up. Little polish, little elbow grease, and bam. You got yourself an archive of the best of the best in old Mac software. Keep it up, for real, I kept telling kids about Bungie and Marathon but they still swear Halo is original.
Yeah I'm not sure how many ports have a Mac build but no Windows build but generally I find that most of these have a Windows port because everyone has Windows, a Linux port because anyone with a spare PC can run Linux, but no Mac build because either no one on the team has a Mac or "the person who did the Mac build left/disappeared" so I'm trying to be that person for everyone, to some extent.
But yeah if it can run on the Mac it can run on Linux and probably does. There's a few cases where it doesn't go the other way (Skin Deep uses OpenGL 4.3 and the Mac stopped at OpenGL 4.1, that sort of thing)
On the wiki on my build system I have a categorization thing happening, perhaps I should incorporate that into the site. https://github.com/MacSourcePorts/MSPBuildSystem/wiki
One thing I try to avoid though there are some examples on the site is recompilation efforts. Those can get into dodgy territory.
