Reclaim Unused Vars

There are a few unused vars that are still coded in other places. This is how to reclaim them.

VAR_DISTRIBUTE_EON_TICKET

#define VAR_DISTRIBUTE_EON_TICKET 0x403F

file: src/field_specials.c
in section bool32 ShouldDistributeEonTicket(void) (lines 3630 to 3636)
delete lines 3632, 3634 and 3635 so the section should now be:

// Always returns FALSE
bool32 ShouldDistributeEonTicket(void)
{
    return FALSE;
}

__

file: data/scripts/cable_club.inc
in section CableClub_EventScript_DistributeEonTicket:: (lines 33 to 43)
delete line 40 setvar VAR_DISTRIBUTE_EON_TICKET, 0
so the section should now be:

CableClub_EventScript_DistributeEonTicket::
	checkitem ITEM_EON_TICKET
	goto_if_eq VAR_RESULT, TRUE, CableClub_EventScript_TryWonderCardScript
	goto_if_set FLAG_ENABLE_SHIP_SOUTHERN_ISLAND, CableClub_EventScript_TryWonderCardScript
	msgbox MysteryGift_Text_TheresATicketForYou, MSGBOX_DEFAULT
	giveitem ITEM_EON_TICKET
	setflag FLAG_ENABLE_SHIP_SOUTHERN_ISLAND
	msgbox MysteryGift_Text_TryUsingItAtLilycovePort, MSGBOX_DEFAULT
	release
	end

VAR_GIFT_UNUSED_*

#define VAR_GIFT_UNUSED_1 0x40DE // Var is written to, but never read
#define VAR_GIFT_UNUSED_2 0x40DF // Var is written to, but never read
#define VAR_GIFT_UNUSED_3 0x40E0 // Var is written to, but never read
#define VAR_GIFT_UNUSED_4 0x40E1 // Var is written to, but never read
#define VAR_GIFT_UNUSED_5 0x40E2 // Var is written to, but never read
#define VAR_GIFT_UNUSED_6 0x40E3 // Var is written to, but never read
#define VAR_GIFT_UNUSED_7 0x40E4 // var is written to, but never read

file: src/event_data.c
in section void ClearMysteryGiftVars(void) (lines 132 to 142)
delete lines 135 to 141 so the section should now be:

void ClearMysteryGiftVars(void)
{
    VarSet(VAR_GIFT_PICHU_SLOT, 0);
}

#define VAR_TRICK_HOUSE_PUZZLE_7_STATE_2 0x40B6 // Leftover from RS, never set

file: data/maps/Route110_TrickHousePuzzle7/scripts.inc

you may have already deleted these sections if you followed Reclaim Unused Flags
(NOTE: doing this will also free up 5 flags FLAG_TRICK_HOUSE_PUZZLE_7_SWITCH_1 to 5)
in the map_script header, delete: (lines 2 to 5)

	map_script MAP_SCRIPT_ON_RESUME, Route110_TrickHousePuzzle7_OnResume
	map_script MAP_SCRIPT_ON_TRANSITION, Route110_TrickHousePuzzle7_OnTransition
	map_script MAP_SCRIPT_ON_LOAD, Route110_TrickHousePuzzle7_OnLoad
	map_script MAP_SCRIPT_ON_FRAME_TABLE, Route110_TrickHousePuzzle7_OnFrame

delete lines and entire sections ( now lines 4 to 93)

	@ Puzzle Room 7 in RSE uses whatever puzzle Mossdeep Gym uses

	@ Because Mossdeep Gym was redesigned for Emerald, theres a good deal of leftover script from the old R/S puzzle

	Route110_TrickHousePuzzle7_OnResume

	Route110_TrickHousePuzzle7_EventScript_UpdateSwitchMetatiles

	@ Leftover from R/S, none of the below metatile scripts are ever called

	Route110_TrickHousePuzzle7_OnLoad

	Route110_TrickHousePuzzle7_OnFrame

	Route110_TrickHousePuzzle7_EventScript_ClearState2
