Still waiting on a Prodigy online emulator, but in the meantime at least somebody recreated MadMaze!

See https://www.prodigyreloaded.com - getting closer to public alpha.

Also all the Prodigy Reloaded implementation is open sourced here : https://github.com/ProdigyReloaded/delivery-system

The reverse engineered client side programs from the various prodigy caches will be shared I just haven’t gotten around to it yet.
