I've got the level layouts translated in the Nick Arcade format (I think, it's been a good while since they were converted). So they are ready to go upon release of everything else. I think I chose that format because it doesn't include the background. I'd be willing (when the time comes) to also separately release the object/art stuff, but I'd want to be clear that this would be my own interpretation and not to be taken as real. It may make it easier for others to do their own ROM hacks with their own interpretations.
