I think the best way to deal with the Apple IIGS and PC/Mac transfer - is to support CD-ROM or USB devices in the emulator. If this can be done, then all is needed to transfer between GS and PC/Mac or between 2 GS (one or both can be in emulation), is a CD-RW or USB device. Not sure whether Apple IIGS - and the emulator - can support this though. Any idea?
