About this Mod

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. ⚠️
