Editing Shops (YW2)

This tutorial is made for YW2, params will change between games so this won’t accurately apply to other games.

First, we need to find the shop you want to edit, navigate over to data/res/shop and open the correct cfg.bin. There are two kinds of shops: special shops and normal shops. This guide will cover both. A list of the special shops in Yo-kai Watch 2 can be found below:

• creature_reward_config.cfg.bin - This controls Jungle Hunter milestones and will also be covered here.
• def_shoplist.cfg.bin - Holds the list of shops - to add a new one increase the ChildCount in SHOP_LIST, duplicate a new SHOP_LIST_INFO and add your new ShopID to it (the CRC-32 of the Shop Name).
  • combine_config.cfg.bin - This controls fusions and will not be covered here as a seperate tutorial covers this.
• another_shop.cfg.bin - This depends on the game but for Yo-kai Watch 2, it’s the bicycle shop; the bicycle shop will not be covered here as it’s too complicated. Normal Shops will be in the format shop_<shopName>_0.01n.cfg.bin - DO NOT edit the ones without _0.01n as they are use a different format, are older, and will be ignored by the game. A normal shop’s ShopName is in the following format:
• shp<type><index>
  • <index> is a 3-digit number used to distinguish between shops of the same type.
  • <type> is a capitalised 1/2 letter sequence used to show the type of shop:
    • N is used for normal shops - this is the most common shop type.
    • M is used for Vending Machines - there are only a handful of these.
    • KP is used exclusively for the BP (Battle Points) shop.
    • TVM is used exclusively for the Day Pass “shop”.
    • B
    • BB
    • BC
    • PAY
    • T

Normal Shops

Adding a new Item

First, in the SHOP_CONFIG_INFO tree, increase ChildCount by 1. Then:

• Duplicate the last SHOP_CONFIG_INFO.
• Change the ShopSlotID to a random CRC-32, you can do this by going to a website like this and typing anything into the textbox there.
• Change the ItemID to whatever Item you want it to give, a list of ItemIDs can be found here.
  • If you want this item to have a limited number of purchases per in-game day, set HasLimitedStock to 1 and edit Stock, otherwise set HasLimitedStock to 0.
  • If you set the ItemID to that of a critter (bugs, fish and insects) the game occasionally let you buy more than 1 at a time - this can be quite infuriating so you might want to avoid this.
• Set ShopValidConditionStartPos to the previous entrys ShopValidConditionStartPos + ShopValidConditionLength and set the last param (ShopValidConditionLength) to 1.
• Next, increase the ChildCount of SHOP_VALID_CONDITION; if it dosen’t have this then you are editing the wrong shop.
• Duplicate the last SHOP_VALID_CONDITION.
• Now, in this new SHOP_VALID_CONDITION, change the Price to either the price of the item or -1 to make it use the item’s DefaultBuyPrice.
  • This trick known as Implicit Pricing dosen’t work for critters aka bugs, insects and fish; it will just get treated as the Price.
  • This is usually in the main currency (internally always yen, so $/£/€1.10 = 110yen, 250w = 100y), although sometimes it’s non-primary currencies such as JP, BP/KP etc.
  • Negative pricing works; granting the player money but will be incorrectly formatted i.e. -1 would be mistakenly formated as $0.-1, £0.-1 or €0.-1 in localised versions.
    • Additionally the game rounds under the limit so if you have 999998 and you buy an item with a Price of -2; it won’t go above 999999.
• Finally, change the Cond to the Cond you want for the shop item - if you always want it to be available set the Cond to 0 (make sure it’s an Integer!) and save your changes.

Adding a new Shop (W.I.P)

This section has not been tested yet, and may not work. Additionally, this section is for Normal Shops; you cannot create new Special Shops, only edit/delete ones that are already programmed into the game.

First, create a shop name i.e. shpN005 for the 5th normal shop; this name must not already be taken. Then:

• Go to def_shoplist.cfg.bin, click on SHOP_LIST and increase ChildCount by 1.
• Then duplicate the last SHOP_LIST_INFO and select the newly created SHOP_LIST_INFO.
• Type your ShopName into a website like this, and set the ShopID to the output the website gives you.
• Then find a _0.01n cfg.bin that’s similar to your shop.
  • Duplicate it and rename it to your shop name, following the pattern of all the other Normal Shops.
• In the SHOP_CONFIG_INFO of your new shop change the old ShopID to the ShopID of the new shop you placed in def_shoplist earlier.
• Change all the ShopSlotIDs to unique random CRC-32s, you can get them by going to a website like this and typing anything into the textbox there.
• Finally, save your changes.

Special Shops

Adding a new Jungle Hunter Milestone

In data/res/shop, open creature_reward_config.cfg.bin. Then:

• If you want a bug milestone focus on CREATURE_BONUS_ITEM_LIST_0, if you want a fish milestone focus on CREATURE_BONUS_ITEM_LIST_1.
• Once you’ve picked your list, increase it’s ChildCount by 1.
• Then duplicate it’s last entry.
  • Set Milestone to the amount of unique types of Bugs/Fish that need to be caught, or 255 if you want all of them to be required.
  • Set ItemID to the ID of the Item you want it to reward, a list of ItemIDs can be found here.
    • Tip: If you want to make it give you 2 Items, create 2 Milestones with the same Milestone requirement.
  • Set Quantity to the amount of the Item it should give.
  • Set UnkID to a random CRC-32, you can do this by going to a website like this and typing anything into the textbox there.
  • Finally, save your changes.
