📋 About This Mod
# LegacyChecker A lightweight, fail-safe utility mod that ensures players have all mandatory mods installed before entering the game. It elegantly solves license restrictions (like **All Rights Reserved / ARR**) that prevent modpack authors from bundling specific mods directly into modpack files. Inspired by the concept of (https://modrinth.com/mod/ftbchecker). This mod is exclusively for 1.12.2 and will not be ported to newer versions — please use modern alternatives for newer game versions. **REQUIRES CLEANROOM** --- ## 📦 Configuration (`legacychecker-common.yaml`) The mod automatically generates a YAML configuration. You can specify as many required mods as your pack needs. ```yaml # List of required mods that must be installed for the game to run. # If any mod is missing, an error screen will block startup or show a warning. # # Structure per mod: # - modId: "The exact internal ID of the mod" # - modName: "The friendly name displayed to the player" # - url: "Direct download link (CurseForge, Modrinth, etc.)" requiredMods: - modId: "jei" modName: "Just Enough Items (JEI)" url: "(https://www.curseforge.com/minecraft/mc-mods/jei)" - modId: "gregtech" modName: "GregTech CE Unofficial" url: "(https://www.curseforge.com/minecraft/mc-mods/gregtech-ce-unofficial)" # If true, the "Continue" button appears, allowing players to skip the warning. # If false, players must install the mods or exit the game. canPlayerLoadGame: false ```
