PlayStation 2 has a history of more than 20 years, but if you want to run a home-made game without adjusting the hardware, it is still difficult to crack. Usually, you need to install Modchip, buy a specially configured memory card, or even pry open the system to block the sensor of the disc reader. However, it may just use the disc itself to deceive the console. Security software engineer CTurt has developed a self-made software method that uses the DVD player function to run unofficial code. This method involves destroying key functions in the files that the DVD movie always contains, and then loading the second, more advanced stage, which is not restricted by the first stage.
The technology is still very young, but it is already pretty good. You just need to put the disc in the PS2 drive and wait for it to load. You can even launch the menu and choose from multiple games stored on one disc. It also hints at the opportunity to allow unofficial games on other systems-CTurt believes this may apply to other PlayStation models. When some PS5 models do not include an optical drive, this may not be a long-term option, but it does bring hope to people who want to use unofficial games to expand their game collection.
