This thread is for notices of legalization for new mods and mod ports and updates for the speedrun.com/mc and speedrun.com/mcce leaderboards, as well as for announcements relating to the use and development of MCSR mods.

Mods can be downloaded from the MCSR Mod List website or using the ModCheck application. The MCSR Launcher can download legal mods as well. The SpeedrunPack modpack is also endorsed, however be aware it may not update immediately.

A brief overview of the mod rules can be found at speedrun.com/mc/resources/pfjbf. it is imperative you familiarize yourself with the rules surrounding the use of mods before submitting any runs.

Please note that MC 1.21.10 is not out yet, but mods have been updated with the release candidate to prepare for it.

We plan to have a follow-up mini mod wave soon for Lithium 1.21.10 at a minimum, but hopefully including a StandardSettings port and possibly more. Longer term, we are investigating how we can use Modrinth for mod storage and distribution.

MCSR Fairplay

MCSR Fairplay is a mod intended to help with anti-cheat and verification. When using Fairplay, you should do /seed after completing a run (even for SSG), which sends clickable text in chat that opens the verification screens. The verification screens show the mods being used, the F3 screen, resource packs, and data packs. After viewing all verification screens, you’ll have the option of creating a zip file containing all files needed for verification, which you should use if you intend on submitting the run.
Some other features of the mod:

  • level.dat is encrypted until /seed.
  • Inputs are logged when you’re in a world and the game window is focused.
  • Save reversion mode (accessible through SpeedrunAPI’s config screen) must be enabled for save reversion. Save reversion mode should remain disabled for runs that aren’t external glitched.

Video showing how to go through the verification screens:

Fairplay is not required as of yet but strongly recommended.

Chunkcacher illegalization

Chunkcacher has some parity issues on certain seeds that are difficult to fix without significantly worsening performance. Due to this, and in light of SeedQueue, we are phasing it out alongside SeedQueue ports. Thus, as of today it is illegal for 1.16.1 and 1.15.2.

There will be a grace period of 30 days to remove the mod, ending at 25 Nov. 2025 05:00 UTC. Afterwards, runs using it on 1.16.1 and 1.15.2 will be rejected.

Updated category extensions

A 1.21.9+ split for All Swords has been added due to the addition of the Copper sword.
