As I recall, a lot of games made assumptions about Mac hardware in the early days, and did things like talk directly to the sound hardware, bypassing the official Apple sound APIs. Those games broke badly first with the 68k AV Macs, which used new special sound hardware that included a DSP. A lot of games came out with "AV Mac" patches so they would work on the AV Macs, and later the PowerMacs (which also used different sound hardware than the earlier 68k Macs). I believe that Lemmings 1.4.2a was such an "AV Mac" patch that fixed the way the sound in that game worked to follow Apple guidelines. - Nate --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Vintage Macs group.
