Exploits Club Summary:

Interrupt Labs shared a post this week walking through the process of cracking the PRNG seed used in the Switch version of Stardew Valley. The post is heavy on reverse engineering, first locating the PRNG functionality by comparing the PC and Switch binary, before giving a detailed walkthrough of the code. The post then uses this RE to develop a seed cracker based on the random “Traveling Cart stock”. It finishes with the code release for both a Seed Cracker and a generator.
