MCInstance Loader

by hrudyplayz

Players who receive modpacks in the .mcinstance format can install them directly with MCInstance Loader, a Forge utility for 1.7.10.

ForgeClient or server, optionalMIT LicenseOpen source1.7.10

What it does

The mod reads a modpack packaged as an .mcinstance file and installs it into the game directory. Files placed in the overrides folder are copied to the Minecraft root, and a carryover folder lets a player add files that replace matching pack content from an earlier install. After installation the game asks for a reboot, and the mcinstance file is disabled so the restart proceeds normally.

Fetched files can come from any internet address and be saved anywhere inside the Minecraft folder. Sided entries limit a fetch to the client or the server, which suits GUI mods. Either side can run it, and neither needs it. The mod is published for Forge only, with 2.7 for 1.7.10 as the latest file from 2023-12-02, and is open source under the MIT License.

The mod depends on the zip4j library by Srikanth-lingala, which it uses to read archives. Its development was inspired by OptionsEnforcer by AstroTibs and by ModDirector from Janrupf and HansWasser. The author says the mod is in an early stage for 1.7.10 and that a port to other versions may follow once it is ready.

Key features

  1. Overrides bundling

    Any file inside the overrides folder is copied to the game root during installation, as in other modpack formats.

  2. Carryover folder

    Players can place their own files in a carryover folder, and those files replace matching pack content during the merge.

  3. Fetching from URLs

    Files can be fetched from any internet address and saved to a chosen location in the Minecraft folder.

  4. Hash verification

    Fetched files are checked against a stored checksum, using whichever of the supported algorithms the source provides.

  5. Hash cache

    Verified files are cached, so updating a pack avoids fetching everything again.

  6. Sided file rules

    Fetches can be restricted to the client or the server, which is useful for GUI mods that only belong on one side.

Questions

Does MCInstance Loader need another mod to run?

Yes. It uses the zip4j library by Srikanth-lingala, which is bundled as part of the mod's own dependencies.

Which loader and version does MCInstance Loader support?

It is published for Forge only, with files for 1.7.10. No other loader or game version is listed.

Do both sides need to install MCInstance Loader?

No. Installing it on one side is enough, since either side can run it and neither needs it.

What the author says

A small mod to allow Minecraft to directly install a modpack in the.mcinstance format, a simplified distribution format for modpacks. It lets people download files, bundle overrides and much more. The game asks for a reboot after installation and disables the mcinstance file to let the game restart properly. I'm just…
