Most USB loaders for the Wii require your drive to be formatted as FAT32. This format has a maximum single file size of 4GB, as it was designed decades ago when such capacities were standard. As you can see below, the original game's size significantly exceeds this, and even after compression, it remains too large for the drive:

To understand the necessity of the "split," one must first understand the nature of the original medium. Super Smash Bros. Brawl (SSBB) was one of the few Wii titles pressed onto a dual-layer DVD, boasting a capacity of roughly 7.9 gigabytes. For the standard DVD reader of the Wii, this posed no issue. However, for the early homebrew community looking to store their libraries on external hard drives or SD cards, this size presented a significant logistical hurdle. The most common file system for removable media at the time, FAT32, had a strict file size limit of 4 gigabytes. Consequently, a raw, uncompressed disc image of Brawl could not exist as a single file on these drives.
Open your favorite loader, like USB Loader GX or WiiFlow. The game cover should appear. Select the game and press start. You can now enjoy the full, uninterrupted Super Smash Bros. Brawl experience from your FAT32 drive!
Some loaders accept flat structure ( /wbfs/RSBE01.wbfs and /wbfs/RSBE01.wbf1 ), but a folder named after the game is cleaner and recommended.
