And that extends to the new Mac OS X "Lion", which drops backward-compatibility with PowerPC-based technologies entirely. So I have to look forward instead of backward, and I have now uploaded new Lion-compatible games. If your Mac has complained in the past about compatibility with my games, simply re-download your games and they should work without complaint.
As for PowerPC-based games, I will still keep them around but I will deal with them on a case-by-case basis. If you, for example, have an old PowerPC-based Mac and you need to re-download and/or re-install your game, you should contact email@example.com directly and I will get you your games.
