Yeah don't give up on PrBOOM, my BOOM port is now at 'end-of-life' and it would be nice to have a more advanced port on my 1200 one of these days
What happened to your Apollo 1260 btw, ever get it to run BOOM properly?
When I first set up my 1200 I had it running, then I started to go through your guide on tweaking my 1200 to make it even faster, which it did indeed do, but it also caused BOOM to start crashing upon launch.
I have moved again since then and am still trying to make ends meet so I've not had my 1200 out and set up for a while.
