Not a lot of reverse-engineering has been done on that one by anyone (including me) but with so little RE I could make the game start & display the first screens.

Thanks to MAME I could workaround the nasty protection (constant bank switching caused by "slapstic" chip) and unlike my other ports, the project is more a fast emulator than a re-coding. It requires AGA because the original game has 16 banks of 16 colors and a 256 color palette which is - added - dynamic. So ECS port would be quite tricky without rewriting the whole game.


ATM it produces a 1:1 graphical arcade port. Sound will be added later.
