I can think of Exapunks[1] (by Zachtronics) which uses a similar concept; you can create games for a virtual device called the "TEC Redshift" and to share the solutions between the players, the game creates a cartridge picture with the name of your solution. The instructions are embedded into the file, and you simply have to drag&drop it into the game to import the solution. It's a neat way of sharing save files!
