How do I install Mod Checker Reworked?

Install the matching mod loader (Forge, Fabric or NeoForge) for your Minecraft version. Download the .jar. Put it in the .minecraft/mods folder and launch that loader profile. Opens on Modrinth — not every file is mirrored on our own servers.

The listing gives Minecraft 1.21.1, 1.21.2, 1.21.3, among others. This is the version stated by the author or source site, not something we verified ourselves.

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

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.

The main font...

Mod Checker Reworked is a mod that ensures that you can use popular mods(that are not on modrinth) in your modpack. You can configuer the mods in a config file! If any of these mods are missing, the mod displays a screen before entering the main menu, showing that you need to download the mods.

I got the idea for this mod from the FTB Checker mod. However, I did not use any code from this mod. Everything is programmed by myself.

⚠️ Mod Checker Reworked is not affiliated with or endorsed by any mod displayed in the gui or Modrinth. ⚠️
