**Standard key prefix**: Allows to redirect the key manager to a file other than `prod.keys` (for example `other` would redirect to `other.keys`). This is useful for testing multiple keysets. Default is `prod`.
**Changing serial**: Very basic way to set debug values for the serial (and battery number). Developers do not need to write the full serial as it will be writen in-place (that is, it will be filled with the default serial and then overwrite the serial from the beginning).
- Battery serial: `YUZU0EMULATOR14022024`
- Board serial: `YUZ10000000001`
If the user were to set their board serial as `ABC`, then it will be written in-place and the resulting serial would be `ABC10000000001`. There are no underlying checks to ensure correctness of serials other than a hard limit of 16-characters for both.
**Changing serial**: Very basic way to set debug values for the serial (and battery number). Developers do not need to write the full serial as only the first digits (excluding the last) will be accoutned for. Region settings will affect the generated serial. The serial corresponds to a non-OLED/Lite console.
