I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
TFC Sophisticated Backpacks Upgrade
Added backpacks and upgrades for TFC
Mod Content
- Six types of backpacks have been added: Bismuth Bronze Backpack, Bronze Backpack, and Black Bronze Backpack correspond to the Iron Backpack; Wrought Iron Backpack corresponds to the Gold Backpack; Steel Backpack corresponds to the Diamond Backpack; Black Steel corresponds to the Netherite Backpack.
- Added various metal tiers of Stack upgrades.
- Added fridge upgrade to preserve food in the backpack and extend its shelf life. It comes with an internal power switch. When there are batteries in the player's backpack, it will consume the battery power to better extend the shelf life of food.
- Added oven upgrade to cook food inside the backpack, compatible with the TFC heating recipes and FirmaLife oven recipes.
- Added crucible upgrade, used for heating or smelting metals in the backpack. The upgrade plugin includes a slot for a bellows. By clicking the button to activate the bellows, the fuel temperature can be further increased. It comes with a power switch. When there are batteries in the player's backpack, it will consume battery power to increase temperature and can be locked at a certain temperature value.
- Added forging upgrade, used for forging items in the backpack. The default is a copper anvil, but you can place a higher-level metal anvil within the plugin and set its level.
Suggest adding a mod, Curios API, and you will have a good game.
