The update by berd_afa is here:

There is also WarpSDL:

The problem with SDL and classic Amigas is that it is dead slow and most games are just about playable only on Amigas with a fast 68060 and a GFX card. Nonetheless, a 68k port would be welcome!
Could you show us some screenshots?
This is an old demo (every port had a different code name, Morocco, Zanzibar, etc). This shows off the basic, tile map, npc conversation, battle. Just remember its not designed to look flash and all that, its purposly designed to look and play like an old school CRPG. (You'd be surprised how many people go eeeeh its not like ultra wide screen with voice acting and patrick stewart in the lead role).
the youtube vid is nearly a year old, and there is a lot more meat to the combat engine than whats in the demo.

As for porting to SDL, I'm not doing anything fancy, its all mostly putpixel and double buffering, so I could theoretically abstract out of SDL.. It just means more work than I had hoped to invest in getting a 68k port going.
