You mean a rel file to be placed as one of the stgcustoms? If it's that, it's okay, I'll do it when I get home
If you mean converting the stage to be playable as a WWR/FD (porting the stage), then the stage would be out of burning lava, there would be lava indeed, but you would always fall through it, and no lava waves or lavafalls would make their appearance
You mean the first option, right?
EDIT: I uploaded the rel for working as STGCUSTOM, not tested but should work
