Hi in regards to the other models of the Vampire. The A500 version is being finalized and tested as there are more features being added from the version seen in videos and forum posts. The A1200 Vampire is being worked on too.
Emulation is always a good indicator for performance and speed. Would love to see this kickstart REAL Amiga development in the scene. I really thing the standalone unit will be something and it that someting is Amiga, Mac, Atari, X68000 or a strange fusion etc then I'm cool with that.
