Modchips compatible with dual layer disks?

[Terry Bogard]

[QUOTE=reddragon105]i'm talking about when a patched DL version is available, will either of those chips play it?

It's got nothing to do with the chip, it doesn't read the discs, that's the job of your laser and how good it is. Any modchip will allow the PS2 to read anything, as long as your PS2 can understand it. Basically all a modchip does is allow you to play any PS2 code while bypassing any protection. Any PS2 with a good laser can read DVD+R DL media, it's how the data is pressed onto the disc that matters.

Movies are no problem, but games like GT4 either have to be patched or like you said, have the right firmware on the chip.
