Truly no man can match the Metal Slug! It impacts with the force of a 38-kiloton bomb that can destroy all bosses. Feel the weight! Every five seconds, the main gun of an Everest-class dreadnought accelerates one to 1.3 percent of light speed. Dev updates: chairgtables Livestreams: This, recruits, is a 20-kilo ferrous slug. This is in preparation for Games Done Quick, which I hope they accept my submission but if not it's cool I have a lot of burgers to eat to keep me happy. Still, the fact that it's possible at all is a testament to the research, ingenuity, and hacking chops of a dedicated group of players determined to unlock the inner workings of classic gaming hardware.White flash for the speedrun timer stop happens at 12 minutes 34 seconds, where the Final Boss General Morgen be like "AAuauaaaaaAAaaaaGHHHHHHHHHHhhh!!!" as Marco explodes him with his manliness. JCog noted that this extreme method probably shouldn’t count for the Paper Mario speedrun leaderboards, since it requires setup from outside the game. You can see the cartridge swap involved at 45:00 in this video, followed by the Paper Mario glitch that takes advantage of that leftover Ocarina of Time memory. With the Ocarina-inserted instruction still stored in expansion pak memory, Morpheus’ glitch doesn’t crash the system but instead jumps the game to the credits cut scene, making for a human-repeatable speedrun solution. As JCog explained, “If we quickly turn off the console, swap cartridges to Paper Mario, and turn the console back on, that instruction will still be there in memory (luckily when boots, it clears the expansion pak memory, but Paper Mario just ignores it).” Today, though, players can still exploit the vagaries of early N64 hardware to move memory from one game to another. “If we let that idle timer reach anywhere from 0x810 to 0x81f, which is 69 seconds (nice), before releasing the stored effects, then execution jumps to expansion pak memory, which Paper Mario doesn't use, and then it crashes from garbage data.” Remember that buffer overflow crash Morpheus discovered in January? It turns out that “by sheer crazy coincidence, this jumps execution to a part of memory where there are player flags and an idle timer,” explained Paper Mario streamer JCog. And that’s where Ocarina of Time and the N64 RAM expansion pak come into play. Unfortunately, the extremely precise positioning required for this method means a human would have no chance of replicating it. A few days later, another runner, Rain, showed off a complete tool-assisted speedrun that warps the player to the game’s credits scene much faster than even the fastest glitch-exploiting speedruns could do previously. Advertisementįray's proof-of-concept video goes into some detail on how the Paper Mario glitch actually works.īy mid-February, though, Paper Mario runner Fray had done the positional calculations and shown off a code execution proof of concept that could be performed with the assistance of emulation tools. Players eventually discovered that Morpheus had accidentally triggered a situation where the game was storing too much data in the “effects matrix,” a data structure the game uses to store details of visual effects like smoke from Mario’s hammer blows.īy using a menu glitch to permanently store what are usually temporary effects, a player can overflow that matrix and enter a portion of unrelated memory, which the game interprets as “garbage” machine code, leading to a crash. The story of how this incredible method was discovered goes back two months, when a Paper Mario speedrunner who goes by Morpheus stumbled on a mysterious game crash in the middle of a livestreamed run. Their new method requires some extremely careful character positioning, the exploitation of “junk” memory in the N64’s RAM expansion pack and, amazingly, playing a couple of games of The Legend of Zelda: Ocarina of Time. There are now dozens of examples of similar glitches that use nothing but controller inputs to insert new programming instructions into classic games, including many that can be performed by humans (and not just button-mashing robots).Įven given all that history, though, we’re still a bit wowed by the speedrunning community that found a way to insert new code into Paper Mario for the N64, leading to a new record-setting speedrun of the game.
