We were skeptical of Vast's claims to have developed a PS2 modchip that works simply by plugging in a memory card when we first heard about it earlier this week, but the company sent MaxConsole a video of the chip in action and it looks pretty convincing. The demo PS2 first fails to boot a backup disc, but then the demonstrator inserts the Vast card and the disc starts right up. Impressive, but we're still a little wary, especially since the demo PS2 in the video is totally opened up. Let's see this on a fresh console straight from the box, shall we? Check the full video after the break.
