FAQ:
- What Launcher is this for? Forge? Fabric?
- Both, check the jars
- Backport to older versions?
- is not planned. There are many features in Truly Modular which have a significantly higher priority than backporting. Once the list of ideas is smaller we might consider backporting.
- is X mod supported?
- probably? Generative Compatiblity has a high chance of working with most mods out of the box. You can check here for more informations or to report issues
- Can i write a Addon for this?
- Can i use this in a Modpack?
- yes
