- If you wanna remove some map, which you don't like, just delete proper XY file.
- If you wanna have different ceremony version of map, like combine with alternative pack, just rename files, basically:

--> mXY_00_0000.gparam / 100/ 200 or more is "Normal version".
----> mXY_00_0010.gparam / 110 / 210 or more is "Ceremony version", just +10.

You can combine all packs as well.
