Quakespasm VS msys2-installer

For those curious about the cause of the issue, you can take a look at the code that loads QuakeEx.kpf (lines 3122-3126). There is nothing to check or sanitize paths, so the case of the string is going to be treated based on the OS's strings.h I believe, which is case sensitive for POSIX and insensitive for Microsoft. It just so happens that much of the rest of the code references external files in lower-case, which is why one may not run into this so often.

Both. There are much better alternatives to QuakeSpasm now, including vkQuake, the newly released Ironwail (name still tentative) and QuakeSpasm-Spiked, although even the latter is beginning to look obsolete now.

I would try to compile

- QuakeSpasm-Spiked, modified QuakeSpasm with framerate-independent physics and other improvements: https://triptohell.info/moodles/qss/

- FTE QW, will let you play singleplayer, multiplayer, and I think even Quake II (and III?): https://fte.triptohell.info/

- QuakeSpasm (sibling comment has a link)

If all else fails, I know some QW guys are playing on M1 using ezquake. That's really a multiplayer engine and I wouldn't recommend it for SP but it could do if you're desperate.

Use Quakespasm Spiked or vkquake

I should say, it worked in my 32-bit vm. So, I guess MSYS2 dropped 32-bit support and hand a maintainer switchover late last year. They renamed some package directories for 32-bit packages and, well to make a long story short, I had a heck of a time getting multilib MinGW set up in my 64-bit env. So, I spun up a Win10-x32 vm, grabbed this awesome dude's fork for the MSYS2-x32 installer, and within 45 minutes, I had your build ready to roll! Whew!!
