All of the functions called by it are prefixed with BattleTowerRoomMenu, but a bunch of them seem more generic than that, since they're part of different mobile menus. Also called another menu jumptable BattleTowerRoomMenu2 for the lack of a better name (only the Yes/No menu functions are used in western crystal). The names of the more generic functions should be fixed when we start labelling other menus.
The UbersCheck and LevelCheck are used only for the battle tower, despite them living in the mobile files. Also labelled some of the known BattleTowerActions.
The former is arguably misleading (as you don’t access the memory location in hl to retrieve the jump location), and is consequently deprecated in newer versions of rgbds. This fix silences these deprecation warnings.
