Storage & USB
Storage and USB drives
Developer Mode gives apps only a limited slice of the console's internal storage, and each app is held to a 2 GB installed size cap. That is fine for the emulator programs themselves, but it is nowhere near enough for a full game library. The answer is external USB storage.
Using a USB drive
Plug a USB drive into one of the console's ports and use it to hold your ROMs, disc images, BIOS files, and save states. With broad file access enabled, your emulators can read and write to it directly. A drive formatted in a common scheme such as exFAT or NTFS is widely compatible and handles large files well.
| Content | Where it belongs |
|---|---|
| Emulator app itself | Internal, under the 2 GB cap |
| ROMs and disc images | USB drive |
| BIOS files | USB or app data folder |
| Saves and states | App data folder or USB |
Practical tips
- Organize the drive on a PC with tidy folders before plugging it in.
- Prefer a powered or quality drive for many large files such as Wii images.
- Keep a backup of saves elsewhere, since uninstalling an app can wipe its data.
Do not rely on the internal Dev Mode storage for big libraries. It fills quickly and is shared across every app you install.
