Does install, but not run: Game is 32 bit - so unless you have 32bit architecture insalled, it won't run. But even if you have it throws a segfault.

Yes, I get the segfault too on Debian 12.1 (bookworm). Here is the backtrace:

Both of you are probably in the wrong thread. This thread covers many different issues, but seg faulting isn't one of them. You should open a new thread if you find a new issue. Unless it's covered by another thread already; have you looked at the thread that actually covers a crash on startup? I've posted a long-winded explanation of one cause of seg faulting there, along with a fix.

I probably would've replied to the earlier post, but I missed it. Debian install issues, which is what most of this thread is about, don't interest me in the least.
