This is a repository for archiving interesting things about the JJ1 alpha--also known as G_MAIN, Universal Game Editor, and Vertigo--since trying to record things in chat services will only result in them being buried and forgotten.

To begin with, to run the game you'll need DOSBox or similar, but you can copy any existing DOSBox shortcut you have (for example, for regular JJ1) and just point it to G_MAIN.EXE.
