weno, pos nbavegando por ps2hd me he encontrado con esta noticia:
DVD9 games on DVD+r dl now playable, including GT4
Up until now, it has been impossible to play DVD9 backups placed on dual-layer DVD+r media due to the different physical format of the data on the disc.. Pressed = PTP, DVD+r = OTP
However, "Team Toxic" has discovered a software hack which enables DVD9 games to load from DVD+r dl media.
This also means Gran Turismo 4 is also playable on DVD+r dl media for the first time, including all other DVD9 games.
The Toxic flash release for DMS4 coming up in the next few days will include DVD+r dl auto-patching to apply this software hack on the fly, making DMS4 the first modchip to fully support DVD+r dl media.
Following that will be a DVD+r dl image patcher which will apply the soft hack to any DVD9 image before you burn to dl, which will let you play the games using any modchip.. That's "Team Toxic's" gift to the scene.
