A way to mod games themselves???

[maverick5992]

Hi,

I have an Idea that might sound stupid.
I have a slim ps2 SCPH-90004 datecode 9D so obviously I can't soft mod it.
I also tried homebrew through game swap trick but apparently they took care of that too by having the console check the disc EVERY time an ELF is called.

So I watched the check and since I'm sure the data has been copied correctly I know it checks for something physical.

I saw the laser going all the way to the center of the disc as far as possible and here's what I saw : It's limits are the BARCODE which is the physical disc check.

Here's my Idea:
What If we could somehow copy that barcode?? (It's impossible I think)
Better : What if we carefully remove the part that barcode is supposed to be (In the Backup disc) and then place an original disc above the backup so that the laser reads the barcode from the original and data from the backup?


I know It's stupid and If it's possible it will need a lot of work and probably special tools specially that you'd not be able to mount it on the console if it goes wrong but it will work on ANY console.
So tell me what you think about it.

The barcode isn't what the Playstation 2's drive Mechanics Controller (MECHACON) checks for.

It tries to read a code that's in the inner-most track of the disc that is out of range of most CD/DVD readers.

That's why people have developed mod chips - to trick the MECHACON that the track/code that it tries to read actually exists and is correct.

And for your own information - the console doesn't perform a disc check whenever an ELF is executed.
If your swap trick fails, then it means that either your game isn't a good candidate for the swap trick, the disc you are trying to swap to isn't readable by the PS2, and/or you swapped the discs at the wrong time or was not fast enough.
