So you want to play OoTR... Setup Guides
Ocarina of Time Randomizer is available in all possible ways by now.
Besides the Web Generator, the randomizer can still be downloaded and executed on your local machine - however, you will need to use Python 3.6+ together with the source code from the Official Github. (in-development releases will also require Node.js to be installed)
To play, multiple devices and emulation programs can be used. OoTR is compatible with N64 hardware via the Everdrive 64 v2.5+ device and is compatible with the Wii console's Virtual Console (WiiVC) via the use of WAD injection. With regards to PC emulators: RetroArch, Bizhawk and OpenEmu are strongly suggested choices.
The base files (ROM files etc.) needed for this are copyrighted and will not be provided.

Recommended Emulators are as follows:
Windows
If your computer is not powerful enough to run either of the above to an acceptable level, then you may try:
Keep in mind that Project64 is not recommended, as it is very inaccurate in its emulation and has known compatibility issues with Ocarina of Time: Randomizer.
