If you have a legal digital backup (an ISO) of your GameCube disc, you can dramatically reduce its file size by converting it into a compressed format.

: If your downloaded "ISO" ends in .exe , .msi , or asks you to install an installer program, delete it immediately . Real GameCube files only end in .iso , .gcm , .rvz , or .wbfs .

When playing Need for Speed: Most Wanted via emulation, you can expect:

: A vast open world filled with "pursuit breakers"—environmental traps you can trigger to disable chasing police cars. Safety and Legal Reminder

A major advantage of emulation is upscaling. You can set the Internal Resolution to 2x (720p), 3x (1080p), or higher to make the game look stunningly crisp on modern monitors. This is a key setting to adjust for visual quality.

Compact ISO is an older, widely supported format that replaces blocks of zeroes or junk data with markers, significantly reducing the footprint on your storage drive.
