Better Compatibility Checker
Changes the default server compatibility check to compare modpack versions

About this Mod
The forge server compatibility checker is not always accurate and can cause some issues with end-users of a modpack when they add a server, and it shows up as not compatible.
This mod fixes that issue when used by modpacks, as it will compare the modpack project ID and the modpack version ID set in a config file by the modpack author and display a tick if they match or an X if they do not match.
Both server and client are running the same version
Incompatible server or client version
How do I configure the mod?
It's simple to configure the mod, first, you will need to open the bcc-common.toml in the config folder, then you will need to set the modpack name and the modpack version, click save, and you're done.
Just remember to update the version when you update the modpack.
Note: Fabric config is named bcc.json
What happens if the mod is not installed on the server, but is on the client?
This mod will check if the data needed is set first and if it's not it will fall back to using the default forge implementation

Better Compatibility Checker officially supports fabric, forge, neoforge for Minecraft 26.2, 26.1.2, 26.1.1. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Better Compatibility Checker – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Better Compatibility Checker consumes the most tick time.
