Suffice it to say that the first minute-and-a-half or so of this TAS is merely an effort to spawn a specific set of sprites into the game's Object Attribute Memory (OAM) buffer in a specific order. Understanding what's going on here requires some deep knowledge of the Super NES' internal sprite and memory management, which is explained in detail here and here. It's at 1:39 in the video where things really start going pear-shaped, as the fabric of the game's reality comes apart at the seams for a few seconds before inexplicably transitioning to Mario-themed versions of Pong and Snake.

Still, it's important to clarify that everything happening in the video is the result of the standard Super Mario World software responding to conventional button inputs-this isn't the result of Game Genie-style external memory editing or the like. It's only through the emulators that allow for input recording and single frame pausing and advancement (not to mention sometimes intense Lua scripting) that these glitches were discoverable and replicable. Most of these glitches are impossible or near-impossible for a human to perform in the course of standard gameplay since they require intricate patterns of inputs that have to be entered precisely at specific frames of in-game video (i.e. In actuality, these seeming impossibilities are just glitches that have been discovered over the years through painstaking emulated playthroughs by the community at TASVideos (short for tool-assisted speedrun videos). At first, it looks like the game must have been hacked in some way to allow for things like multiple on-screen Yoshis, item boxes that spawn multiple 1-ups, and the ability for Mario to carry items while riding on Yoshi. The two-and-a-half minute video of this incredible exploit is pretty tough to follow if you're not intimately familiar with the state of emulator-assisted speedruns. The most remarkable moment of the weeklong marathon, though, came when a robotic player took "total control" of an unmodified Super Mario World cartridge, reprogramming it on the fly to run simple versions of Pong and Snake simply by sending a precise set of inputs through the standard controller ports on the system. The event focuses on live speedruns of classic games by human players and included a blindfolded Mike Tyson's Punch-Out!! run that ranks among the most impressive live video game playing performances I have ever seen. This was demonstrated quite dramatically last week at Awesome Games Done Quick (AGDQ), an annual marathon fundraiser that this year raised over $1 million for the Prevent Cancer foundation. What's more surprising is that such "arbitrary code" bugs are also present on the relatively locked-down computers inside of video game consoles.

This glitch can only be deactivated by quitting the level, or resetting the game.In the world of personal computing, hacks that exploit memory errors to allow for the execution of arbitrary (and often malicious) code are far from surprising anymore.

It can also infinitely raise the player's coins, giving the player up to 99 lives in the process. Yoshi Double Eat Visual Glitches Game Crashes Berry / Power-up FreezeĬollecting a stored item on the same frame as eating a berry with Yoshi will cause the game to freeze. This will cause Mario to flash from red to green similar to if he touched a Super Star. When a P Switch is pressed, swallowing it with Yoshi or grabbing it and taking it through a Warp Pipe will cause to the P Switch to return to normal and can once again be used. This is caused by the placement of the objects, which writes data into the game's memory and can be exploited to cause the warp.Ĭollecting a power-up on the same frame the timer runs out will allow the player to continue controlling Mario after the timer hits 0. By defeating enemies and loading and placing objects in precise locations in Yoshi's Island 2, it is possible to warp directly to the game's ending sequence.
