## TaCZ Pack Upgrader
\n**This mod is completely unrelated if you’re using the official TaCZ**
\nAutomatically upgrades the gun packs to be compatible with TaCZ 1.21.1<\/p>\n
## Basic Usage
\n1. Install the mod
\n2. Put the gun packs into the `tacz` folder as usual
\n3. Launch the game and the packs will be upgraded and loaded automatically<\/p>\n
## About `.jar` Files
\nThere are two types of `.jar` files in the context of TaCZ:
\n1. `.jar` gun packs
\n – Maxstuff, Daffa’s Arsenal, Gucci & Vuitton Attachments, LesRaisins Append Pack, etc.
\n2. `.jar` mod addons (which still can include gun packs)
\n – TaCZ Tweaks, LesRaisins Tactical Equipments, TaCZ Durability, etc.<\/p>\n
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<\/p>\n
You need to put the `.jar` gun packs into the `tacz` folder, not the `mods` folder
\nAfter that, everything should be handled automatically<\/p>\n
## Troubleshooting
\n– Some gun packs may contain some dependencies to some of the mod addons (e.g. LesRaisins Tactical Equipments)
\n – In that case you can’t really do anything, since those addons doesn’t exist on 1.21.1
\n – Maybe you could find an older version of the pack that doesn’t have the dependencies<\/p>\n
