Here are the ropes used in diverse pirate ships of DKC2, but in layer 3 format. Sure there are other BGs from other DKC games, but those are on layer 2. Perhaps I'll try to rip the layer 3 versions. Here's what you can do:
-view the layer 3 BG in the sample level;
-full 512x512 compatibility. The original was 512x256 and it was a bit weird;
-layer 3 BG uses 65 8x8 tiles. Moved the transparent tile to tile FC, This can be quite useful;
-added 3 sample levels with their own palette;
-every sample level has its own .pal and .palmask files.
