About Stardew Predictor
This app simulates the random number generator used in Stardew Valley and makes "predictions" about the game either from the Game ID or by reading the save file. Currently, the information predicted includes special mine levels (e.g. mushroom floor & infestations), random items sold by some vendors, results from cracking geodes, the train schedule, and more.
A useful companion tool is BlaDe's Map Predictor which handles things such as artifact digging, giant crops, and mine ladders.
All changed & added content from version 1.6 should be supported; 1.6-specific features will only appear in the results if either the save is detected to be from that version or the app is launched with a URL id parameter.
The app is written in Javascript and uses jQuery, BigInteger.js, JS xxHash, and pako; it is hosted on GitHub Pages at https://mouseypounds.github.io/stardew-predictor/ and the source code repository is https://github.com/MouseyPounds/stardew-predictor. It is released under the MIT license.
Please report any bugs, suggestions, or other feedback to the topic in the Stardew official forums or to @mouseypounds on Discord.
