Wolfenstein 3D, can't turn in-game music on when run on StrongArm or newer
...reminded me that I have a copy of the Wolf 3D source code (Powerslave released the source on their site sometime after iD released the original as GPL). IIRC I was able to use the source to build my own StrongARM/RISC OS 3.7-compatible version of the game, including removing the copy protection and fixing/disabling the CPU detection so that the in-game music would work. If you're interested I should be able to dig up the original sources plus the changes I made to get things working. And (from running Wolf 3D under ArcEm) I'm also reminded that there's a bug in the save game code where it uses OS_Find 0 to close all open files, with the side-effect that it doesn't work if you had the wrong filesystem selected when you started the game. So that might be a good one to squash for any future releases.
