Description

## TaCZ Pack Upgrader **This mod is completely unrelated if you're using the official TaCZ** Automatically upgrades the gun packs to be compatible with [TaCZ 1.21.1](https://modrinth.com/mod/tacz-1.21.1) ## Basic Usage 1. Install the mod 2. Put the gun packs into the `tacz` folder as usual 3. Launch the game and the packs will be upgraded and loaded automatically ## About `.jar` Files There are two types of `.jar` files in the context of TaCZ: 1. `.jar` gun packs - Maxstuff, Daffa's Arsenal, Gucci & Vuitton Attachments, LesRaisins Append Pack, etc. 2. `.jar` mod addons (which still can include gun packs) - TaCZ Tweaks, LesRaisins Tactical Equipments, TaCZ Durability, etc. The upgrader can handle gun packs, but not mod addons; it's impossible to upgrade mods from 1.20.1 to 1.21.1 programatically You need to put the `.jar` gun packs into the `tacz` folder, not the `mods` folder After that, everything should be handled automatically ## Troubleshooting - Some gun packs may contain some dependencies to some of the mod addons (e.g. LesRaisins Tactical Equipments) - In that case you can't really do anything, since those addons doesn't exist on 1.21.1 - Maybe you could find an older version of the pack that doesn't have the dependencies ## License [LGPLv3](https://github.com/MUKSC/TaCZPackUpgrader/blob/main/LICENSE)
