Tetris Max 2.9.1 and Macintosh System 6.0.8 bugs

31 years ago Tetris Max for the Macintosh was born, an improved clone of Tetris, and it became an insanely popular Mac game during the 1990s. I may or may not have had some involvement in its development. Macintosh System 6 was the current OS version at the time of the game’s release, but System 7 was introduced shortly afterwards. It’s recently come to my attention that the final version of Tetris Max (v2.9.1) may not work when running System 6 on certain Mac hardware, even though the game was advertised as System 6 compatible. I haven’t yet been able to fully verify this myself, but there’s a Macintosh Garden bug report from ironboy36 in 2022, and more recently a detailed bug report complete with video (thank you James!). Obviously I need to fix this stuff ASAP – 31-year-old bug be damned. And I need your help! Consider this a group debugging effort.

This is such a cool story. If anyone can contribute to fixing this – please help them out.
