All you need now is KickTOS!

I am confused. It says it's an Amiga 1000 kickstart disk but it's already had kickstart loaded, otherwise you wouldn't get the hand.
Atari ST emulation on the Amiga isn't new, you could do it back in the day.
If I had an A1000 I might be tempted to make it boot from ROM and turn the WOM into RAM (pretty sure there was a way of doing that). However I think ultimately I would leave it original.
