Pokémon Crystal - Examining the out of bounds glitches TheZZAZZGlitch 2019-11-26 | Gen II is notorious for its weird out of bounds glitches.

Pokémon R/B/Y: Bringing arbitrary code execution to other games TheZZAZZGlitch 2016-12-17 | 8F not only gives us control over the whole game, but over the whole console.

VBA 1.8.0 & VBA-RR: Stack buffer overflow in XPC file parser results in code execution TheZZAZZGlitch 2016-09-12 | First I break the games, then I break the emulator.Don't use VBA. Use mGBA or VBA-M instead.(Read the description for more information)DESCRIPTION FOR INFOSEC PEOPLE:Just download the PoC+advisory here: sites.google.com/site/thezzazzglitch/home/VBA18_CodeExec.zipDESCRIPTION FOR EVERYONE ELSE:This is an arbitrary code execution vulnerability in the old and discontinued VBA emulator, including VBA-RR.It's possible to run untrusted code on the computer by loading a specially crafted XPC cheatlist. You can imagine someone using this vulnerability to create a cheatlist that installs a virus, then giving it to you, disguised as an 'awesome cheat code for level 255 Arceus in Red/Blue'.Remember how in the Pokémon games one could trigger a buffer overflow bug to execute his own code on the console? This is exactly the same thing, but on emulator level. An attacker can create a custom cheatlist that does whatever they want on your computer. In the video, I make it run calc.exe, because that's how I roll.If you want to test it for yourself, here's an example exploit for VBA 1.8.0, along with a PDF explaining the technical side of the vulnerability: sites.google.com/site/thezzazzglitch/home/VBA18_CodeExec.zipAdditionally, I have received a lot of opinions that this feature is rarely used, so the vulnerability is of low severity. I don't believe that. Let's say I do a glitch video that presents an Arceus hack in Red/Blue, and I say you can try it yourself by running an EXE file. Not many people would try it, I assure you. Now, I instead tell you to try an XPC file, and tell you to import it through the 'Import Gameshark Code file' option. Works best on VBA. Now it sounds a lot better - it's a Gameshark code list, it can't be dangerous. Would you do it?Code execution is always dangerous, because it breaks the basic security principle of "only executables can do anything to your computer".

Pokémon Blue: 99 item stack glitch and its applications TheZZAZZGlitch 2016-08-10 | "It never hurts to have extra items!"Gen I is so awesome, even having more than 99 items can cause it to break.

Pokémon Blue in 69 A presses TheZZAZZGlitch 2016-07-08 | The amount of memes I received in the comments forced me to think how the A Button Challenge would look like if applied to Pokémon games.

This is because in a complete playthrough, the half A press would just be held out and continued from an A press in an earlier segment, and it wouldn't necessitate pressing the A button. So the half A press is just a continuation of an A press that was performed earlier in the run. You can watch this video for a more detailed explanation (or you don't have to, because you've probably watched it already): youtube.com/watch?v=kpk2tdsPh0A&t=35sThere are currently no cases where holding A is important in Pokémon games. However, it might become useful in any time, and thus, the half A press notation is mentioned and allowed in advance.
Pokémon Blue: B1F does everything... given enough time (predictable SRAM corruptions) TheZZAZZGlitch 2016-06-19 | Previously, I used SRAM corruptions caused by glitch Pokemon sprites in conjunction with B1F to randomly create wonderful glitchy effects. But is there a way to actually manipulate SRAM into useful data? There is, but it certainly ain't easy.My previous video about B1F: youtube.com/watch?v=JEEB41Lz59cAlso, my previous video about glitch trainer 0xFC and its first roster: youtube.com/watch?v=wjXQqZTYJcoAll of the code used in this video can be downloaded at: sites.google.com/site/thezzazzglitch/home/SRAM_Corruption_Emulator.zip
Pokémon R/B/Y: Mew Glitch textbox ID matching - glitch mart (and more!) TheZZAZZGlitch 2016-06-02 | The Mew Glitch holds a lot more secrets than any of you could have imagined. People intended to use it to get Mew. Then we used it to make people disappear. Now we can use it to buy some conveniently priced glitch items!

Pokemon Blue: 5 minor glitches/oversights TheZZAZZGlitch 2016-03-18 | 5 glitches that are not game-breaking, yet still interesting.Who decided that this game is ready for release, anyway?
Pokemon Diamond: Effects caused by glitch moves TheZZAZZGlitch 2016-02-25 | While most of the glitch moves in Gen IV games are not particularly interesting, move index 0x01F6 definitely exhibits some interesting behavior. Arbitrary code execution coming soon?
Pokemon Blue: Glitches caused by scrolling past the sixth slot TheZZAZZGlitch 2016-01-16 | Even just scrolling through Pokemon beyond slot six is not safe for your game.
RNG plays Hearthstone TheZZAZZGlitch 2015-12-14 | Everyone keeps complaining that games in Hearthstone are completely determined by luck. So I decide to test that statement by creating a script which randomly generates mouse input and feeds it to the game. Will pure RNG win at least one match?The script in question: http://pastebin.com/raw.php?i=umfUukHUObviously it's not production-quality code. For the script to work correctly, Hearthstone must be set to run in windowed mode, with a non-standard resolution of 1026x630. Requires PyWin32 and Python 3.Control the application through hotkeys: Alt+R starts sending mouse inputs, Alt+P ends the turn and stops sending mouse inputs.(Twitch Plays Hearthstone anyone?)
Pokemon Yellow - 4 4 (hex BF) and its interesting behavior TheZZAZZGlitch 2015-12-13 | I tried to reproduce the "4 4's true cry" (youtube.com/watch?v=1dQq6_xa8-U), but failed miserably. Instead, I have accidentally stumbled upon some other quirks of 4 4, which made this Pokemon even more mysterious than before. The rare example of me actually having no idea what's happening with this game anymore.
Pokemon Yellow - Encountering Yellow-form Missingno. without crashing TheZZAZZGlitch 2015-10-25 | Whether Missingno. crashes the game or not is determined by the contents of SRAM bank 0. In other words, Missingno. derives its behavior from an unused chunk of data in the save file. By manipulating that chunk of data it's possible to make Yellow Missingno. relatively stable.Item list (starting from box item 15):Any Item x2Lemonade x10Ultra Ball x4Potion x10X Speed x2Awakening x99Parlyz Heal x81X Accuracy x1Fresh Water x2Soda Pop x2TM02 x12Guard Spec. x2
Pokemon Blue: The mystery of B1F (glitch item 0x55) TheZZAZZGlitch 2015-08-21 | B1F is a glitch item executing code from $A7D0. This is where Hall of Fame data resides. What could possibly go wrong?We can use Missingno. Hall of Fame data corruption just to see some glitchy wonderful things, or cleverly manipulate the Hall of Fame data to execute arbitrary code. The choice is yours.
