I took the liberty of patching up the Atari Lynx database from Hyper List to include the latest updates from the No-Intro database. It is in sync now with the 2017-02-04 version.
It contains the playable prototypes as well as the missing Baseball Heroes official cart. I left out the Protos that have an actual release version.
