The "USB Loader GX USB Compatibility List Exclusive" is not a fixed document—it is a set of hardware rules. The exclusive knowledge is this: Old, slow, low-capacity USB 2.0 drives outperform modern high-speed drives. Stick to legacy hard drives or small flash drives, use a Y-cable for power, and format with 32KB cluster FAT32. Ignore the "official" lists that claim USB 3.0 works—in practice, it's a gamble you don't need to take.

To maximize compatibility with any drive, ensure your settings match these requirements:

USB Loader GX requires a dedicated USB drive (not shared with other purposes) for reliable operation due to the Wii’s limited USB stack and power delivery. Not all USB drives work. Compatibility depends on three factors: controller chipset, power draw, and partition scheme. This report lists confirmed compatible drives, incompatible drives, and technical workarounds.
