What is the issue with Playstation 3 system backwards compatible with Playstation 1 games?

What is the issue with Playstation 3 system backwards compatible with Playstation 1 games?

I thought it was perfectly ok. Twin Galaxies member Rotunda said their was a problem, something about emulator, is what he said valid or theory.

    It's the difference between what legacy TG had as a rule (not permitted) and what seems reasonable to TGSAP era. The legacy argument against is that it is emulation but legacy TG also permitted PS1 games on PS2 slim devices which is also emulation. So there's a big crack in the reasoning of the legacy TG. Unless someone can prove there is an advantage to OEM PS3 emulation of disc-based PS1 games then it should probably be acceptable.

    TG's baseline today seems to be hardware is what matters so I don't think it should be acceptable. It's not original hardware, its emulation. If I can get PSX PC emulator to run a PS1 original disc should that be allowed as PS1? Nope. Emu should be emu.

    While the hardware argument of the PS3 slim may be technically true, lets compare that to hacked wii games and Everdrive submissions which seem to have been (thoroughly?) discussed and accepted by the community:


    The Ps3 scenario is 1st party games, being played on an official backwards compatible 1st party console.

    The Wii scenario is a hacked unofficial console playing ripped unofficial data.

    The Everdrive scenario is an unofficial cart playing unofficial data in a 1st party console. The Everdrive also uses emulation in the fact that it is emulating hardware in the game, such as the SNES SuperFX chip and the dozens if not hundreds of similar chips used in a myriad of cart based games.

    Also with the Everdrive and Wii scenarios, no one knows if the game data is truly unaltered.
    With the Ps3 scenario we know for a fact the game data is official and unaltered.

    If Sony makes a device designed to run a game that is designed to run on a Sony device, who cares what the tech behind it is.

    The only thing that comes to my mind as an issue could be if a later device has a faster disc speed and loads things faster which could impact timed runs.

    The Playstation Classic was released by Sony and contains Sony approved ROMs. Should it be considered emu or Playstation 1?

    historically tg seemed to allow any official device as fine. so playing atari games on colecovision with a device atari sued over by lost the lawsuit? go for it. super game boy, well at least it was released by nintendo, go for it. as far as i can tell "original" just meant "legal, commercially available".

    with consoles released after tgsap launched though we really dont have to follow those old rules. sure for the older systems we need to stay consistent, but i think for the newer system we can figure out better rules for them case by case.

    i'm a fan of apples to apples and not mixing and matching.

    If I ran the place, I would have no distinction between original console, emu, and classic except in instances where it can be determined that the game functions differently between them.

    I have not touched a PS3 in a long time, and even at that it was to install a hard drive about ten years ago. To my knowledge the PS3 board contains the PS1 chip, but some (most?) PS3 consoles do not have the PS2 backward compatibility. Mind you I am trying to recall something from 10 or so years ago. I'd defer to someone who recalls better information about specifics on the systems.

    There is a significant difference between the PS2 and PS3 playing PS1 games as the PS1 architecture I believe is part of the PS2 and PS3 system components. Compare this with the original Xbox and the 360 which had no shared or similar components in their system design. The 360 runs an emulator to emulate the original xbox games is the necessary point I want to make here. On the other hand I do not believe the PS3 or PS2 use emulation at all to play PS1 games.

    In a slightly less relevant note, something like the ps1 mini (and all the other so called mini systems) is little more than a raspberry pi based emulator.

    I always thought that using a PS1 disc on a PS3 was just as acceptable as using a PS1 disc on a PS2. I mean, unless there's something that I was unaware of that gives an unfair advantage or something?

    NTSC versus PAL for racing times differences especially on longer races.

    Sony the company made PS-3 console and PS-2 and PS-1.

    Main thing that all Twin Galaxies members concern is does it give the player advantage if does not then it is ok all good on the video game submission.

    Like I stated before, I am almost entirely certain that the PS1, PS2, and PS3 all use the same internal hardware to run PS1 games. There is no emulation involved with these consoles compared to the microsoft consoles that all do not natively have the hardware of the previous consoles, so they have to rely on emulation to perform their "backwards compatibility".

    To test this I played Brigandine for a bit on my PS1, PS2, and PS3. Unofficially I'd say the latter consoles loaded faster going from section to section. For the time being a simple eye test kinda thing. For the purposes of loading times, the PS2 and PS3 were superior in loading things faster, but the gameplay was otherwise in all aspects entirely the same. Someone more knowledgeable of the modern consoles might want to shed some light into this.

    I personally feel like playing a PS1 game on a PS2 or PS3 is far more akin to the Atari 2600 games being played on the Colecovision via the expansion module. It is (to my limited knowledge) a hardware thing with playstation systems and not an emulation like the microsoft consoles are doing to have any level of backward compatibility with their games. I consider the ps1 mini an emulation as the guts of that are little more than a raspberry pi based board.

    From a speedrunning perspective, I'd want to shave time everywhere I can so having a system load the game faster provides the most optimal time. From a gameplay perspective at least, I did not notice any difference between the systems.
