The basic idea is that all item locations in the game have their items shuffled around… so for example you never know what you’re going to find when you open a treasure chest! There are many item locations in the game beyond treasure chests, for example overworld heart pieces and NPC’s that give you items - these are all included too!
The VT Randomizer is a web based rom patcher that will allow you to make a randomized rom from one you supply. It is meant to always have the newest things available as the Randomizer team develops them.
This was written and is maintained by Veetorp. A big thanks to Dessyreqt, ChristosOwen, Smallhacker and Karkat for their work - without which none of this would have been even remotely possible!
The VT Randomizer is an entirely web based randomizer, There is no download client for it. That being said the ROM is patched entirely in your browser. Being a web version we can get the newest features availble to users as quickly as possible. Click on Generate Randomized Game above to get started.
There is a downloadable client version of the Randomizer (currently on v7) maintained by Dessyreqt which can be found here: https://dessyreqt.github.io/alttprandomizer/
Many features being tested in VT will land in the client version in the future.
