Hypercard "Player"? Oh the pain, it's all coming back to me! (To those who don't understand... Hypercard was originally free but when it was spun off as part of Claris, they tried to charge for the real thing and only offered the "Player" for free. Hypercard was already disintegrating from neglect but this really hastened its demise.)
I really wish a proper version of Hypercard was in this emulator. I'm too young to have used it at the time, but from what I've read it stands for an important ideal of what personal computers can be that's been forgotten and I'd like to experience what that was like first-hand.
