We've learned in the last few years that a significant chunk of older Apple II software had copy protection that took advantage of undocumented functionality of the old machines and won't actually run on upgraded Apple II hardware.
Also, some emulators have chosen to not support WOZ images.
That makes it all the more important that we preserve cleanly cracked copies alongside the originals, and that's where a substantial chunk of my effort has been-- getting stuff into the Apple II softlists.
This month will have a pretty serious flood of Apple II disks. Don't know if I'll be able to keep it up next month, but I'll try my best.
