Frequently asked

Do I need to install LegacyOptimised on the client or the server?

The client only. There is nothing to install on the server side. That is the author's declared design, not a guarantee for every server: one running anti-cheat or missing a counterpart mod can still object.

What licence is LegacyOptimised under?

CC-BY-NC-4.0, as stated by the author on the platform we synced it from. Check the project's own page before redistributing or bundling it.

How do I install LegacyOptimised?

Use a launcher that imports packs, such as Prism Launcher, the Modrinth App or the CurseForge app, and open the pack file with it. The launcher installs the right loader and mods for you; installing a pack's mods by hand is the error-prone way.

Where do I download LegacyOptimised safely?

Start with the author's page on Modrinth, which is where the data here is synced from. MCReference does not host or repackage files. The download link goes to the source recorded for that release; verify the publisher, filename and checksum before running it.

Which Minecraft versions does LegacyOptimised work on?

The author has not declared a supported version in the metadata we sync, so there is nothing here we can state as fact. Check the project's own page before installing it, and treat an old modpack with no declared version as untested on modern Minecraft.

Details from Modrinth, where the author last updated it on 8 Feb 2026. We do not host files and we do not republish descriptions; every download link points at the author’s own release.

Not indexed yet. Score 45 against a threshold of 55. The page still exists and is still linked; it simply carries noindex until we hold more.
