Introduction
Getting started with Yu-Gi-Oh! Forbidden Memories modding.
Why use Timtam?
Timtam is a specialized toolkit designed exclusively for Yu-Gi-Oh! Forbidden Memories. Instead of using generic hex editors and scattered community scripts, Timtam brings patch injection, memory mapping, and save editing into one unified web interface.
Is Timtam available offline?
Yes, there is no need for a constant internet connection. Processing is done client-side.
CAUTION
While Timtam processes ISO files entirely in your browser using WebAssembly, you should always keep backups of your original .bin or .iso files before applying patches.
What is SLUS-01411?
SLUS-01411 is the North American release of the game on PlayStation 1. Most modding efforts, memory addresses, and patches within the community are based on this specific version. Timtam currently targets this release natively.
