To successfully rescue the princess in Super Mario Bros with a mere 500 points, you must play with extreme caution. Avoid stomping enemies, refrain from collecting coins, skipping mushrooms or flowers, and make sure to hop on the flagpole at the very last moment.

The most challenging aspect of this endeavor lies in level 8-1. In this level, executing the jump requires precise timing for liftoff, holding the jump button, and executing a wall jump – all of which must be frame perfect. With NES games running at 60 frames per second, every input must be timed within 1/60 of a second.

Furthermore, your starting position before running must not only be on the right pixel but also within a specific x sub-pixel range. In essence, this jump is an incredibly frustrating task that demands impeccable precision.
