I agree, it would be awesome to see this optimized for the Amiga, I am sure it would likely be absolutely amazing. I love the Genesis and it does have some quirks but man, in the right hands, it can produce some amazing games (Treasure, Konami, Sega, etc proved this).
Anything is better than nothing, and I have no right to belittle the port itself since I have no talent in creating anything like this. I just like to dream a little with these articles. Lol.
