Time to make Tekken modding great again, gone the days of conflicting mods that use the same item to replace something

Allows to add custom item slots, highly beta. made it back in late 2020 but never had the time to polish and release it to the public

Documentation

First time run

Extract the file to where TEKKEN 7.exe is and launch TKDataPatcher.exe, it will extract all the relevant customization item data from the game and put them in TEKKEN 7\TekkenGame\Content\ModData\customize_item_data\TEKKEN PROJECT DO NOT EDIT THE FILE ITEMS.CSV IN TEKKEN PROJECT, instead use it for researching and understanding the items in the game

As user

Every time you add new .csv files to TEKKEN 7\TekkenGame\Content\ModData\customize_item_data\ then you'll need to run TKDataPatcher.exe to patch the game's files to reflect the changes

Items will sync online if two people have the same mod with the same shop item ID otherwise the opponent will see the default outfit

As modder

Adding your own item

Create a directory in TEKKEN 7\TekkenGame\Content\ModData\customize_item_data and call it yourname or whatever, then create a file called items.csv or coolmod.csv Any file will work as long as it ends with .csv, you can have multiple .csv files in one directory too

An example csv:

561001,-1,nsd_bdu_1p_cus,0,56,9,-1,0,NIN_CUS_008,0,-249,0,1,5,0,1,-255,0,-1,\x00,0

This is just Lidia's 1P colorable item but with the item ID of 561001 instead of 560001 SHOP ID has to be unique, if the tool gets popular then we might get conflicting IDs but at least the end user can change the ID, so this is way better than the conflicts we have right now.
