Teaching Mario to Play Pong and Snake Through Innumerable Exploits

This is the coolest classic Super Nintendo Entertainment System (SNES) hack we’ve seen in quite a while. What you’re seeing is called “Super Mario World (Total Control)” by [Masterjun]. Our first recommendation is that you , then come back here for an explanation. Similar to what we saw for Pokemon Yellow on Gameboy, [Masterjun] created entire Pong and Snake clones within Super Mario World. He also created a menu and ending screen, along with his trademark smiley face graphic. Even more amazing is that this was unveiled live on a real SNES running an unmodified game cartridge. [Masterjun] actually used dual multitap cables, effectively connecting 8 controllers to a SNES. This gave him enough bandwidth to quickly download his new binary through the controller ports alone.
Welcome to the world of Tool Assisted Speedruns (TAS), where emulators and scripts are used to create high-speed runs through video games. The runners often work frame by frame, painstakingly inputting commands to create the perfect run. Game bugs and glitches are often exploited in these speed runs. In fact, in runs such as this one, the speed run takes second place to showing off the exploit. The output of speed run creation is a script file of control inputs which can be executed on an emulator to “re-run” the TAS at any time. This script can also be saved to a PC or Raspberry Pi and played back into the controller port of a real game system. A PIC based hardware translator is used to convert the data to NES or SNES controller format. As one might expect, these scripts run open loop. With no feedback from the running game, they can and do become desynchronized due to differences in console hardware, such as the tolerance of the oscillator crystal. When everything is in sync and does work , the results are awesome.
