How PS1 security works.

A message for gamers as the holiday season is here:
Hey Folks, it is the shopping season and that means most of us will be buying gaming stuff in November and December. Wololo.net will be looking for the best deals and let you know about them. For example in July 2016, our twitter followers and mailing list subscribers were among the first to know about an Uncharted 4 Special edition deal for $19, a 75% discount at the time! Follow us on twitter to stay up to date. I also suggest to subscribe to our deals mailing list below for full deal updates. Note: this mailing list is mostly useful for people in the US.

    Well, i’ve sucessfully transfered my psp and ps1 saves from my psp ms to my vita. I think i can do the same thing with the games. Well, i’m thinking to upload my resident evil 3 backup folder to anyone with a backup folder in you pc to paste in it and tranfer to your vita just to see if works. Do you agree???

  2. Ahora si, Maestro, he ilumunado mi memoria ya que siempre utilice estos metodos pero desconocia la seguridad y la forma de hackearla. buen tema.

    PS1 kicks *** I used to make backups like crazy in 96 in HK selling it to tourists those were the days 🙂 economy was better than now this time corporations want to see us killed in jail for giving to people what they deserve in wholesale instead of rip off price of 70.00 110.00 Usa dollars a game at the time.

  4. Hi there,

    back in the days there where Modchips which claimed that they would only allow imports to be booted (so burned discs/gold discs still failed to boot with these multinorm chips).

    How did they work?

    My guess is that they took the SCEx string on the disc (so they actually checked that string or they did not bypass this check) and converted it into the string of the corresponding bios of the PS1?

    Does anybody know how exactly those multinorm chips works?

    PS: Which discs got the SCEW string? These discs would only boot on Net Yaroze consoles (and on chipped PS1s). The only disc I could think of is the Net Yaroze boot disc in the Net Yaroze dev kit? Are there any other Net Yaroze exclusive discs

    My Cousin had a PS1 with some blue thing in the back of it, and every time you booted it up, a screen would come up saying START and you had to press X on it.

    You haven’t mentioned Libcrypt protection which was used on later PlayStation games.

    I had a PSone once that could boot burned games directly without any tricks on the console itself, and it wasn’t modded.

    However, producing the burned copies DID require some trickery. For one, the data tracks in the BIN file needed to be ripped as “MODE2/2352”. You can check this by editing the CUE file in any text editor, like Notepad. If your ripping software had settings for “read/igore bad sectors” or similar, TURN IT ON. Second, the disc had to be burned in raw96r mode.

    If either of these two steps weren’t done correctly, it would reject the disc. Also, region-mismatched games needed a swapdisc that could override PAL/NTSC, which I simply burned as well.

    Or at the very least, I couldn’t locate any modchip. The drive assembly failed at one point, and I only could find a “fat” PlayStation’s drive assembly to replace it with, which worked, but wasn’t shaped properly to allow the console to be properly reassembled.

    It’s been about 10 years since I had this thing, as I eventually got a computer fast enough to emulate a PlayStation and no longer had to burn discs, or play with the lid sensor of a no-longer-fully-assembled PSone.
