How to Edit Map Jumps in Yo-kai Watch 2 and 3

Original guide by @lit_8 on Discord. Slightly modified by @n123original. This guide assumes you already know how to navigate romfs and use CfgBin Editor. If not, please read the starting guide. Additionally, this only works on map jumps, so normal entrances and some basic doors. No XQ controlled jumps so, no doors that require items, no elevators, and no trains.

• First, extract and open mapenv.pck from data/map/<MAP> in Kuriimu2.
• Next, extract <MAP>_funcpt.bin from it, and open it in CfgBin Editor.
• Next, search through the PTREE trees with MAP_JUMP parameters, until you find the one you want
• Next, edit the MapID on the right of the string and the number if needed to make the string unique.
  • For example, you might change MJ_t101g00_t106g00_01 to MJ_t101g00_t102g00_01 or MJ_t101g00_t102g00_02, if the former already exists.
• Finally, save and replace it back in the mapenv.pck.
