If the FOOBAR trick doesn't work, consider these alternative methods:
: You can try disabling disc checking by editing the game's configuration files. This method may require technical expertise and is not recommended for novice users.
. The game checks for this specific "marker file"—likely a remnant from the original developers for testing—and should now skip the disc check entirely. Why This Works
The "Please insert disc 2" error is a frustrating relic of early 2000s DRM, not a sign that your copy of Need for Speed: Underground 2 is broken. By applying the No-CD patch (specifically the community-vetted ThirteenAG fix), you will not only eliminate the error but also unlock widescreen resolutions, better framerate stability, and the ability to play without an optical drive.
This bypasses the disc swap failure.
