I just uploaded version 1.2.1.098 to AmiNet and the Zone.
This version uses an older version of the ScummVM engine and should be more usable on real ECS hardware.
Here's a little video of it running on my AGA machine:

This special build of ScummVM is performing a real-time 256 color to 64 color (ECS) optimized conversion every time the palette changes. Each frame rendered has to be converted from the game's chunky pixel format to the Amiga's native planar format (display is also double buffered).
The ScummVM GUI is converted from 65k colors down to a palette of 64 optimized colors just once at program startup.
