Module modpack 

Modpack installation: Modrinth (.mrpack), CurseForge (manifest.json zip) and ATLauncher and FTB (online packs).

Every format follows the same flow: parse the pack, install vanilla + the loader via install_with_loader, extract overrides/configs into instance/{name}/.minecraft, then download the files listed by the pack. The *_files entry points only install pack contents, leaving Minecraft and its loader for a later launch. They do not create instance_config.json.

Modules

atpack

ATLauncher packs, installed from ATLauncher’s online API.

cfpack

CurseForge modpacks (a zip holding manifest.json and overrides/).

ftbpack

FTB packs installed from remote version manifests, without a local pack format.

mrpack

Modrinth modpacks (.mrpack).
