spongeh posted:It doesn't. There's a category of runs for cool glitches like that. This is obviously taking the glitch to an extreme. See the original Super Mario World run. This one technically completes the game, although it doesn't become the canonical run since it heavily breaks the game. Am I understanding this right... he abuses a glitch that makes it possible for him to alter the state of whatever part of the rom he likes, and then he alters it in such a way as to actually write a brand new program (pong and snake) and then execute it? As in, he literally turns the game into an assembly language editor and writes a completely new game (reusing graphics from the original game?) Because if so, that's insanely cool

It's not the ROM (as it implies, Read Only Memory) but essentially he is using all sorts of bugs that normally corrupt memory. Instead, he shifts around everything enough to eventually cause the next piece of code to run to be from the same place the controller input is read from. It's similar in practice to a buffer overflow in a piece of software for your desktop, the difference is the code he's trying to overflow with was fed in through 8 controller ports (2 multitaps) Normally, these kinds of bugs will crash the game in unpredictable ways, but if you understand what it's changing, you can control it.

In short, here's what he did: 1. Manipulate objects in such a way that a part of the game's memory spells out a series of machine instructions to jump to controller input 2. Exploit a glitch to spawn a nonexistent object that has the address of the portion of memory he just changed 3. Swallow the object, causing the game to jump there and start executing the bits from the controller as code. 4. Instruct the console to write to memory a small program that reads bits from all available controller input lines (multitaps) and write those bits to memory until some signal to stop is received. 5. Instruct the console to go to the first memory address you just wrote. At this point, you now have a fully functional assembler, allowing you to create any program the console has the memory to store. This particular run was limited by the capabilities of the playback device (they actually plugged a computer into an SNES's controller port to do this run), but you could conceivably put an entire NES game into the SNES's memory.

It would take a while to write it out, but it's entirely possible. They said in AGDQ that they wanted to load SMB over SMW with the trick then speedrun it live, but time limitations plus limitations of the replay device prevented that. Somebody in the TAS discussion thread suggested doing the trick in All-Stars, but instead of writing an entire program, just modify the existing game so that doing certain things (hitting certain blocks, getting certain powerups, etc.) would put you somewhere in a different Mario game, essentially making all five games into one big game. I think that would take more time coding than just copying SMB, though.

PRL412 posted:You don't have to have played Dark Souls to watch this: What's funny is this is how  AI deals with being dragged out of their designated area by wanting to murder you dead, they start backpedaling the moment they stop caring about you, and won't attack you until they reach their original station or you poke them. A couple of tough enemies can be made complete jokes just by abusing the fact that they'll drop what they're doing to backpedal back to start.What's -really- funny is when a certain enemy encounters a corner and the game's clipping decides it's having none of that. https://www.youtube.com/watch?v=l6SlFmBzd7I Kobold eBooks has a new favorite as of 09:18 on Jan 8, 2014 |

I've been playing through Assassin's Creed 3 and playing the Homestead missions like the previous posters said, when I got a glitch during one of them. There's one side quest where you have to herd some pigs. I finished it and was in the cutscene and talking to the NPC when I suddenly got attacked by a wolf. Connor was on the ground being mauled and the screen was flashing red but I couldn't do the QTE so he died while the NPC was still talking to him like nothing was wrong. Apparently it's pretty common, but no one has managed to get it on Youtube yet.

I like to think that it isn't a glitch; the homesteaders are just super hardcore and impossible to rattle.

What's drawn to the screen is "typed" in via the controller input after the injection is finished. There's a detailed explanation in the submission comments and the code itself in the forums.

The only joy in that game is trying to break it. I always got a kick of flinging that one gem over invisible walls or the gem that shrinks you and gives you infinite jumps because they never got around to the effects depleting the energy bar.

Speaking of Gamebryo, I've found the patch notes for the Unofficial Oblivion patch to be a veritable goldmine. Fixed Dro'Nahrah's daily attendance AI being set to Bruma instead of Bravil castle, which caused her to die in the wilderness. Edla Dark-Heart should no longer attack the player's horse for no apparent reason. Shamada, Ra'Jahirr and Julitta Plotius will no longer each futilely try to open a locked cupboard in Best Goods & Guarantees for two hours a day. S'drassa will no longer have an "Invest 500 gold in this shop" option for an Expert in Mercantile player, as he doesn't buy or sell anything.

Kinda a small one, but while playing Splinter Cell: Blacklist, Sam suddenly wanted to be a kid again and pretend to be Superman by putting his arms behind himself and pretending to go really fast. Also he forgot how to bend his elbows.  (for some reason his arm animation broke and both of his arms were stuck pointing in one direction. Even doing something like pulling out a new weapon or using a laptop did not fix this and it only stopped when I died)

I finished Assassin's Creed 3. I had a glitch in the final Homestead mission when (big spoilers ahead) I was hanging up the painting after the Achilles' funeral. Achilles was in the cutscene, stoking the fireplace underneath the painting. I thought it was part of the quest at first like a flashback, but he was just hanging around the manor as usual, going from room to room even though we'd just buried him. Creepy, especially since some of his idle dialogue is something like "Can't get any rest around here". Video of the glitch here. I didn't get this glitch however: https://www.youtube.com/watch?v=93C6m39QRdk

Right, the video is basically a nonstop Loony Tunes-esque madhouse of slapstick shenanigans and shoulder-tapping pranks, except it's all taking place in a heavily booby-trapped jungle full of fascist death commandos in the middle of the Cold War. I thought I was being funny and clever when I managed to bullshit my way through a strongly fortified base by throwing spiders at everybody, but that video is just nuts.
