This is the Atari 2600 release of 1 Monster Truck Vs. 61 Children. It is playable in an emulator on on real hardware.
To play this, you will need an emulator, such as Stella, or a cartridge to load the ROM from on an actual Atari 2600, such as the Harmony Cartridge. To play, press the fire button to advance from the title screen, and then keep on mashing that fire button to charge your engine. Your engine's charge status is the bar in the lower right corner. You will have one minute to charge your engine, and the time can be seen as the bar in the lower left corner. Will you make the jump?
To reset at any point, use the Game Reset lever, and to go back to the title screen at any time, use the Game Select lever. The Player A difficulty switch toggles the sound effect, with A being on and B being off, and the Player B difficulty switch toggles the music, with A being on and B being off.
I hope you find this game as enjoyable as I do!
