For retro gaming enthusiasts and data hoarders, the Nintendo GameCube represents a golden era. However, with a full library exceeding 1.3 Terabytes (uncompressed), storing every classic like Super Smash Bros. Melee or The Legend of Zelda: The Wind Waker can be a storage nightmare. This has led to a persistent, controversial corner of the emulation scene: the “Highly Compressed GameCube ROM.”
