Mod Library

Each one is a self‑contained Crazy Engine port. The artwork tells you what it runs on: a disc for browser mods, a cassette for PSP, a computer for Scratch. Official releases & updates live on itch.io.

No mods match your search.

Submit Your Mod

Built something in Crazy Engine? Upload your .zip to Google Drive and paste the link below — it goes straight to the review inbox. If it makes the cut, it lands in the library above.

Upload the .zip to Google Drive, Dropbox, MediaFire or itch.io, then paste the share link here. Files can't be attached to this form — mods are far too big to email — so the link is how the mod reaches the library.

Set the link so anyone can open it. On Google Drive that's Share → General access → Anyone with the link. If it's locked to your account I can't download it, and the submission can't be reviewed.
Submissions go to the review inbox. Zips are checked before anything gets published — expect a reply within a few days.

Loading a mod takes 3 steps

01

Grab a disc

Pick any mod from the library above and hit download — you'll get a single .zip, untouched.

02

Open the loader

In the engine screen, find the mod / load button and choose "load from file" — no need to unzip anything first.

03

Select the .zip

Point it at the file you downloaded. The engine reads the chart, song and level data straight out of the archive.
