PS2 optical drive exploit makes homebrew games and backups playable with out hardware mods – TechSpot

The make use of can be utilized for a couple of things. As pointed out, homebrew games and burned backups are possible. CTurt revealed a video running a backup of Shadow of the Colossus (above). Another shows the PS2 running a Super Nintendo emulator (below). It is also possible to put multiple games on one disc (providing they are little sufficient) and run them from a start-up menu.

Because the system believes it is preparing a DVD for video playback, this method totally bypasses the PS2’s physical disc copy defense. It is distinct since CTurt claims it is the only exploit that does not use non-native hardware like network adapters, an HDD expansion, or a modchip. It also does not include physically blocking the disc tray sensors. All that is needed is a disc.

“There’s really no factor this general attack circumstance is particular to the PlayStation 2 as all generations support some mix of burned media: from the PlayStation 1’s CD support to the PlayStation 3 and 4’s Blu-ray assistance, with the PlayStation 4 having just eliminated CD support. Hacking the PS4 through Blu-ray BD-J functionality has long been gone over as an idea for an entry point,” composed CTurt. “This may be something I would be interested in checking out for a long-term future task.”

Without going into the technical details, which you can read in his blog site, CTurt created a corrupted IFO file that creates a “big read overflow.” Basically, it loads an ELF (Linkable and executable Format) file– the type used in homebrew games– into the system’s cache, which is then pressed into the primary memory by the overflow.

Modding the PlayStation 2’s hardware to play homebrew video games and backup discs might be a thing of the past thanks to an exploit discovered by a security scientist. CTurt developed software application called FreeDVDBoot that uses the PS2’s DVD gamer as an entry indicate bypass disc checks at the software application level. No hardware modification is needed.

In context: The PlayStation 2 just celebrated its 20th birthday on March 4. Although the console is rather dated, it still has lots of enjoyable and enjoyable video games. Its age also makes it a fantastic candidate for playing and creating homebrew titles, since voiding your service warranty is no longer a problem if you mod the hardware.

The PlayStation 2 will not load burned game discs, but it will check out burned DVDs. CTurt saw this as a potential attack vector and began exploring how the PS2’s optical drive plays DVDs. He eventually discovered that the hardware starts DVD loading by checking out the disc’s IFO file and writing information to a RAM cache.

While FreeDVDBoot does not have support for all DVD drives used in the PS2 line, he is dealing with expanding support. Guidelines and the needed files are posted on GitHub for those interested in trying it out.

He also says that since all optical drives, including CD and Blu-ray, operate on the same principle, the make use of could possibly work on anything from a first-generation PlayStation through to the PS4.
