You can edit archive with UndertaleModTool https://github.com/UnderminersTeam/UndertaleModTool/releases/tag/bleeding-edge Thanks for the info - that's at least a start for some research. Sadly, the tool doesn't work correctly for this particular archive though as you can see: I'll look around in the source code, maybe it gives me some idea as to how the format is structured.
