I have been following a discussion about what arcades should be ported to Amiga.
The discussion is in the EAB forum
While we do have this version https://www.youtube.com/watch?v=VH3emf7NGg0
It is a very poor Amiga conversion, this is what I would consider a better rework (see above). The Sharp X68000 version I have used to create this concept. Could possibly reuse Graeme's Rygar engine, especially if you wanted parallax effects (8 colour background) and 16 foreground.
The player is a hardware sprite (16 colours), Foreground and background combined (no parallax)
I personally would prefer more colour over parallax in this instance unless we can get both :)
