No.24588 Robbbert Moderator Aug 12, 2026, 02:55	With the release 0.289, the CD is not recognised and won't run. With current GIT, the game starts up and appears to play normally. I'm not exactly sure what I should be looking for.

No.24591 JimCarlTay Senior Tester 31 days ago	@Robbbert In version 0.289, make sure "Start Application" is selected in the system menu when the CD is loaded. Then the game will start running.
