Core v5 for the AppleSqueezer GS was released recently. It fixes an issue that a few users were having with sound on early IIGS motherboard revisions (at least, for 2 out of 4 people who reported this to me), and I’ve also received some limited feedback that it improves VidHD compatibility. VidHD was working for many already, but this should improve things further, and means that if you were still using v3, you should be able to now use v5.
If you were one of these users, please report back if this indeed improved things for you. v5 can be downloaded here:
