    i know exacly what your talking about we've all herd these same warnings
    for many many years since cd burners were 600+ dollars

    but the GD drive can and dose read further on the disk
    when you account for that buffer zone between sessions

    like mentioned before 99 min cd-r's were popular for dreamcast backups
    alls i know is they have been documented to work just fine on the dreamcast

    and as far as i understand how the CD spc works
    is the laser path is all the same length its not documented how long that path is

    from my understanding the spc has the laser turn of at the 74 min mark
    but in reality if you send out of spec commands you can make the laser hit its bump stop

    as far as i know the CD drive only takes its orders from the TOC
    the TOC says shut the laser off at this min mark so it dose
    if the TOC is long then the laser would stay on longer

    the only special commands i know of are the ones used to write the high TOC/overburn a CD to the bump stop

    other then the TOC i have no real explinashion of how a cd drive could read so far because even with tighter tracks DVDs take up more surfiace area on the 12 CM disk

    also i have to correct in my last post where i say 1mm when i mean 1 CM
    epic fail on my part

    It's sad I read an article on the playstations history where sony wanted to use cd's that were designed to be a lot more scratch resistant. But kutaragi stepped in and said it be better to use this cheaper media he found to save on costs.

    Honestly it is almost impossible to have ps1 games that are in mint with no scratches or oxidation. Longest I had last with no scratches was Final Fantasy Chronicles and even that finally got some scratches after a year. And you better hope your games don't have any cracks, cause i borrowed a game from a friend once that had a tin crack in the corner with a slightly deep scratch below it, tried to buff it out so my ps1 would read it, disc literally broke in half.

    Fact is sony just used a cheaper cd media that most cd manufactures wouldn't use. Only time I have experienced oxidation that resulted in broken discs were some sony dvd-rs I once bought. Lesson learned most sony media is cheap crap.

    I just checked some hundred discs, and for some reason the bottom of
    final fantasy tactics is different color than black, it's more grey-blue and the data can be seen.

    Correct. It is not black. It is a blue / purple. It looks black, because there is no light to reflect on it. Kind of like how people with black hair, actually have brown hair if you look at it with the sun on it.

    My PlayStation discs have that white cloud also. Only some. Mainly the ones I have stored in a draw with zero light, in their original cases.

    Do you think it would be possible to remove that black / purplish blue 'ink'?

    I mean, to really know if it is the same as a CD-ROM (PC standard), then we need an electron microscope to match pit by pit and notice where the 'copy protection' pit lies... :p

    It had nothing to do with copy protection the only reason they couldn't be copied properly was because some games contained XA audio along with CDDA which no other software at the time supported that's why CDRWIN invented the .BIN / .CUE sheet format, later CloneCD did come along with subchannel support so you could defeat libcyrpt protection though by working out the differences and manually patching the image yourself with a ppf or a hexeditor.

    So there is no 'secret' pits that a PC CD-ROM reader cant read?

    Well what was everyone going on about then?

    Maybe in the video they did it as a scam to trick us all...

    I just thought, it was a prevention to stop scratches. I mean, a thin layer of 'ink' will stop light ones, but not all. Then again, wont the 'ink' shorten the pits height?

    Sony have a history of just making shit up when it comes to consoles.

    The PS2 was supposed to have Toy Story quality graphics.

    I can back up exactly what he said, they WELL over played the capabilities of the PS2, the same thing they did as we all know with the PS3.

    Though from those overblown demos to the actual games, the PS3 is the one platform where the devs have actually come almost close to delivering something like they promised during the time when the hype machine was in full swing.

    haha, that's funny. Why would Sony do such a thing?

    Gaming now is all about how great the graphics look. No one cares about the gameplay anymore...


    ... But back on topic for ASSEmbler before it gets out of hand.

    I just inspected a new copy of lunar 2

    The whole disc is frosted, and the three lines where the top plastic was poured
    onto the pressed part is visible.

    I hold great fear for the durability of psone games.

    This is so bad. Why did Sony have to use this in the pressing process!

    Modchips where then invented, the games 'protection' from the ink has been exploited and the truth was set free that it did nothing (except prevent scratches).

    Why didn't they stop using it and actually try to stop piracy / modchips in the hardware...

    No.

    Very no...

    Not in this life time, I'm willing to bet on that.

    There's no way they were going to stop using the trademark black disk PS1 production. Also they did try to address piracy on both fronts, one of the reasons you have to swap discs twice on certain models and have to solder more wires into your PSX which doesn't even guarantee that every game will work burned.

    At no point did they stand idly by while end users ripped off games.

    Yep it's part of the reason they removed the parallel and serial port from later models, as far I know nothing was officially made for the parallel port the serial port allowed link up play irc with Gran Turismo and other driving games.

    That's why digitization of data and HDD loading is a must nowadays.....
    I think all future consoles shall have HDD installation of games - u just have to put original media to identify that u legally own a legally-bought copy....

    Play LA Noire on XBOX360 slim and u'll see how melting hot your dvds get...
    I played my legally bought LA Noire on my CFW'ed PS3.....Ripped it to jb files, applied the official patch.....Original Game Disk is resting in its case forever...

    I do not condone piracy in any way.....just wanna have a collection of originals that will last ....
