In the early 80’s, piracy on Atari home computers (and most other brands) was rampant. It was popular for pirates to add as many cracked (or dumped if it was a cart like Miner 2049er) and “trained” games on a disk as would fit along with a tiny, crude menu to launch them. Training a game meant adding cheats, usually activated by a simple menu shown upon launching the game. Miner 2049er got the same treatment as every other game. No exception!
Pictured here is a pirate disk full of games, the menu to launch them and the cheat screen. Last level!
