Then if you closes the cd tray, the level would load and you could land your huge trick.

I was doing A “shareplay” on psp with 2 other people and we all played metal gear portable ops plus online against each other using this technique. I’d put the game in and load us all to the home menu, put the disc back in my psp (host), start A private match and once the private match starts you can take the disc out and put it in another psp and that person can join once they join get the other(s) to join and bang, three people playing the same game as if you all bought it and only one person needs to have the game: save some time and money.

    Very interesting, I would have never guessed that PS1 games were able to load so much of the levels and graphics into RAM/VRAM, I would have guessed it had to constantly read from the ROM. What might be more impressive yet is just the sheer resilience that games from that era had in terms of not crashing when moving data around. The code was built really sturdy compared to Windows 95/98 equivalents that used to crash if a fly landed on a nearby desk. lol

      @shidoro Год назад +10

      That glitch was very common in the Test Drive series..I remember I had a very bad Test Drive 4 CD and saw the same behavior. what I believe that is happening is that the background is loaded in VRAM, but then the game tries to load road textures/collisions/etc and fails so it leaves you with just the BG, but in fact it is not "misbehaving" because the other game is being read, it is just not loading anything else in memory.
      If you would like to test that, you can just open the CD cover and see if the same thing happens.

    I can see why this has happend. A ps1 disc will actually stop spinning when it has finished loading that part of the data on the disc. E.g. a menu with all the cars and music swapping.
    However, the ps1 will read the disc for the next bit of the data. Which would be the race or scores. The reason you can still play while you have swapped the disc is that that part of the disc is already loaded.
    You can actually try playing the game when you have taken the disc out. However, the music might automatically stop. The game will crash if you go past a part of the game that needs loading. Therefore, forcing you to restart the ps1 console.

    • @HulluHapua

      Some Games Will Still Run Even With Another Disc, Because On Most PS1 Games, Most Of The Already Loaded Data Will Be Stored In The RAM Until New Loaded Data Will Overwrite Some Unnecessary Loaded Data, A Press Of The Reset Button Or A Turn Off Of The System.
      There Are Also Some That Store Literally The Entire Game Into The RAM Such As Vib-Ribbon, That Uses The Disc Swap Technique For Playing On Tracks Of An Audio CD For Example. Though It's So Simplistic Graphically And There Is Simple Sound Effects Because Then It Will Work. (Also It Doesn't Have Loading Screens Because Of It)

You could induce some amazingly glitched out worlds including stuff like unlimited respawning treasure chests, just stand on the tile and pick the lock or cast the unlock spell, harvest unlimited gold and occasional weapon or armour drops. Then restore the disc and enter a town (if there is one on screen, you better hope!) and all was well again, except you were rich AF. Good times, good times.

    The results make sense. Anytime it looked for new data, it couldn't find it because the internal file names and/or some of the structure is different. Songs probably are numbered rather than named, hence why they are swappable. Textures and level data are much different between the two.

      First game says "read from x sector to find y data" games are swapped, second game says "x sector has some b data and some j. Nothing related to y" game console doesn't know this and just displays b and j as if it were y.

    What I believe is causing the glitched textures is that during loading the code is still loaded from the first game and the code is loading in data from specific addresses off of the CD and loading it into memory, however when the code attempted to display the images, the bytes it was reading from those addresses that were loaded into memory maybe isn't even image data causing that issue.

    Unfortunately even on the same engine, things will get shuffled around so everything won't end up loaded the same way. If you DO want to try datamashing games like this though, it's always a better idea to try and get a later title to load an older title's data, since the newer title will have data the older game wouldn't even know about, but the newer one may have failsafes/fallback data for.
    Also as Nick points out below, some PS1 games like Vigilante 2 used this to let you play content from the previous game, although in cases like that it was the developer setting up the later game to just check a disc ID. The V8 levels are actually on the V82 disc, iirc.

    • @shidoro

      Another nice example of PSX games handling data mashing "correctly" is the Theater Mode in the Tekken Series.
      In Tekken 3, after you complete the game with some (or all characters, don't really remember) you unlock the Theater Mode and if you replace the Tekken 3 to Tekken 2 or 1 disc, it will allow you to see the Cutscenes of those games. Pretty neat if you ask me :)

    • @iselink

      Memory pointers can't be similar enough, it must be loaded into RAM into exactly same places.
      Also pointers must be same datatype (i.e. char can't be int because char is smaller (1 byte) than int (4 bytes)) and pointers must point into memory with same size (in case of arrays).
      Otherwise program will be shot for segmentation fault (for reading from memory not allocated by program in better case, in worse case it can read his own memory with different data in it).
      If what you described works, then both games must use same game structure with same engine which allows to read and load data from CD.
      In another words, all characters have some ID only and are defined by some structured data so game engine can read models and textures from CD event that model have for example 5× more polygons and textures are 2× bigger than original.

  • @StopBuggingMeGoogleIHateYou
    @StopBuggingMeGoogleIHateYou 3 года назад +257

    There's a simple explanation for all of this. A) the part of the code needed to run the menu is loaded into memory, so the disc does not need to be in the drive. B) the audio tracks are stored separately from the game data (the disc can be played in an ordinary CD player). Therefore, there's not much mysterious or impressive about the fact that you can play music from one disc in another game. C) The game crashes when you try to do anything that requires loading data off the disc, for many reasons, the primary one being the game does not know where to seek on the disk to find the data it needs / the data at those locations is not what it was expecting.

    • @jacobrzeszewski6527

      Hence the weird colors. The loading instructions executing from RAM don’t care if the data is good, just that the data is there. It’s likely just random data stored on the disk. Stuff like this fascinate me, like the Super Mario Land out of bounds data.

      @@od3stroyer771 it’s because the CPU instructions that load the image data don’t have the correct data. When the first disk is loaded, those load instructions are loaded into RAM. Those load instructions are looking for a specific place on the disk where the image is stored. When the disk is swapped, that location no longer contains valid image data. However, unless there is a redundancy check programmed into the game, it will just load whatever random data is in that location on disk in that location as though it’s an image. Since it’s likely random data, the image is literally just random. You should watch Retro Game Mechanics Explained’s video on MissingNO. It goes into incredible detail on how this works. And it’s probably similar to what happens here.

    I love this stuff. Driving out to the void was scary. That loading-screen kind of outcome is common with this stuff where everything in ram early enough is fine (Perhaps even some gameplay) with future reads for map data, textures and their decompression being borked and potentially crashing given the mismatch between discs. I've been trying to remember for years, but there was a disc for one console which could boot in another because the architecture was the same - despite not being unplayable. I'd love to remember which game and two consoles that quirk was on.

    What you're seeing at 3:51 is actually byte data (likely code) interrupted as an image.
    I made a project a while ago that turns any file into an image and they all resemble this.
    Likely whats happening is its reading from some address on the disk that it expects to be an image or similar, its hitting a chunk of code instead. and trying its best to render the code as an image.
    Then promptly gives up and some exception is thrown. really cool!

      @@dudearnav yeah, the way memory may be stored on a demo disk as to where things are located relative to other games will inevitably not line up and fail when you hit data not loaded to console memory. However, if you had like an e3 or public demo build disc that was used for conferences or development, it might very well somewhat work, granted games can still frequently fail after removing the disk at all.

    @kosmasraptis8374 Год назад +2

    This happens because, as many have pointed out, the pointers to the game data are different. E.g. a texture for a car on one game is not on the same point on the disc as the texture of a car in another game. The only way for this to be possible, is if the 2 games and the CD images were specifically designed with this in mind. Because, another important point is that 2 games can never have the exact same engine, unless they were developed at the exact same time by the exact same developers. Because even if they technically use the same engine, they're going to use different versions of the engine where some code has changed to be improved and that changes how the whole CD is laid out.
