    Those wanting to take their original PlayStation to the next level usually needed to open up the system and install a modchip; that's been common knowledge since even the '90s. However, a user named Socram, previously known for creating amiitool, has released an exploit that makes modding your PS1 easier than ever before. Called "tonyhax", because it utilizes Tony Hawk's Pro Skater 2 or 3, it loads specific data off of the PS1's memory card that "unlocks" the system's disc drive, which then lets you run other region games or even backups.

    After "extensive testing", Socram has decided to release their exploit to the public, source code and all. The full project is available on GitHub, while a writeup and documentation as to how tonyhax works is available on their website. The creator says that the exploit is possible because in either Tony Hawk's Pro Skater 2 or Tony Hawk's Pro Skater 3 (NTSC or PAL), the game doesn't check if a skater profile name has been edited or messed with in any way. Should you edit the skater name in a dramatic way, it overwrites the memory of the system, which in turn allows custom code to be run.

    You'll need a PS1 memory card with tonyhax on it, to which Socram recommends using a PS2 and Free MCBoot to copy it. After loading the profile in-game, the exploit will boot up, and your CD drive will then accept games, even if they're burned CD-R backups, or games from other regions. Tonyhax works on all PAL PlayStation consoles, NetYaroze, and all NTSC-U systems except the original SCPH-1000.

    This is super cool. I don't think I have any way to move a modded save to a PS1 memory card at this particular moment, but this is definitely something I'm 100% going to get around to doing at some point since I don't really want to install a modchip in my PS1 and the disc swap method is annoying :lol:

    This is actually one of the coolest things in awhile! I wonder if this could lead to solderless methods for loading roms from an sd card since it seems like the only reason you need to solder for xstation and the like is for disc protection stuff or so I believe.

    tonyhax author here.

    I've had some crazy ideas about maybe creating a custom SD to memory card adapter, since both SD cards and memory cards use standard SPI. It wouldn't be even necessary to open the console or touch anything inside, just an adapter much like on a GC.

    For now I'm gonna focus on trying to port this exploit to other games.

    Actually someone has made one very recently! https://8bitmods.com/memcard-pro-for-playstation-1/ < Still not released (and a little expensive, IMO) and it's just for making tons of virtual memory cards, but I assume someone could easily write a firmware to do exactly that :lol:

    Mad respect to you. That was some amazing work.
    It would be really nice to get SD to Memory Card adapter- would really be handy for both PS1 and PS2 uses. either it happens or not, I respect your decisions and appreciate all your works.

    The interesting bit is that you don't even need to make a custom firmware or use any fancy circuitry. If my memory serves me correctly, the PS1 on the memory card uses just standard SPI - that's exactly what SD cards use too.
    You couldn't use it for saving in games since the commands are different, BUT you could indeed talk using custom software using nothing but a passive adapter.
    I once did for fun a NetYaroze boot card using an Arduino. It just waited the console to emit a particular SPI command, and then replied with what the NetYaroze boot disc expected.

    Ohh,nice.
    It's always interesting to see old console's exploit being released.

    I thought I wouldn't need to swap games on my PS1 anymore (it's an original launch day SCPH 1002 with swap support), but from what I understand, it's a "swap-loader" method using an original game disc, for non boot swap-compatible consoles.
    I thought it was something like PS2 FreeMcBoot directly loading the memory card's exploit, but it's not like that. You always need to play Tony hawk to unlock and "wait for lid", which means it's not compatible with multi-disc games, right ? (Chrono cross or Parasite eve requires disc swapping without saving first)

    or is the unlock hack working with in-game swapp ? that's very great for everyone if it works :)


    Thanks for releasing it :)
    It'll be helpful to many users. It's always nice to have multiple choices !

    edit:
    Having SDCard adapter for memory card would be great too !

    Hey! Wonderful work here man. That's a very intriguing idea and I honestly would love if something like this could happen. I want an sd method for my ps1 but I just cannot do the intricate soldering needed for most every option out there.
