Hypercard GS 1.1 is a lot like mac 2.0, but as far as I recall, just for your information, you can't convert HC Mac 2.0 stacks to the GS, since they use a non-standard screen size and color. You can, however, convert Mac 1.x HC stacks to the GS using Hypermover (a two part step, on the source stack machine and on the destination stack machine). -Auri
