It would still entail a lot of additional work I simply wouldn't have the time for. Candles, moving objects and bosses would have to bee added at a minimum, plus there's that missing bottom line in many of the horizontal areas (thanks to the way the SNES displays things) that I'd prefer to see completed, and the fact that the stage graphics go ugly or missing very quickly once you get away from visible areas.
Honestly, the raw maps are great to have, but to get them to a state I would be personally satisfied with (and I'm rather finicky), I'd pretty much have to redo the whole thing over and use Tropicon's work as a guide.
Hopefully, someone with more time and more SNES mapping expertise will attempt this.
