Some mods target the Mono version of the game, which is available by opting into the Steam beta branch "alternate"
Polyfill
Your old mods stopped working after a Schedule I update? Polyfill patches the game so a lot of them run again. It patches the game, not your mods - your own files are never changed, and one console command takes the patch back out.

The game gets an update. Mods made before it stop working. Polyfill patches the game so they run again.
It patches the game, not your mods. Your own files are never changed, and polyfillrestore takes the

Good to know
- Made for Schedule I 0.4.6 and 0.4.7
- Asks once if it may send anonymous reports: your mods, what broke, how long you played. Never your name, your save or your folders
- Only changes things on your own PC. Your save is untouched
- In multiplayer, everyone using the old mod needs it too
- To remove it:
polyfillrestore, restart, delete the two files
For mod authors
Your mod probably has a page on polyfill.doomods.com already:
- what it is missing on each game version, by name
- errors from players' sessions, with the method they came from
- a live badge for your README or mod page
- all of it as JSON, no key: API

Schedule I by TVGS. Built on MelonLoader and Mono.Cecil. MIT licence.
This mod is written with help from generative AI tools (Anthropic Claude, OpenAI Codex).
If you have fun with it, a like on the Thunderstore page really helps other people find it (thumbs up next to Download, you need to be logged in) - ty either way, and lemme know if anything breaks or you've got ideas
The compatibility index runs on a server I pay for. Tips: ko-fi.com/doodesch
