For example, to tell the Harmony cartridge to use F4 bankswitching with Superchip support you
would rename the file cavein.bin to cavein.f4s (the extension is not case-sensitive).
* Custom bankswitching is not a specific format but rather a stub that allows new
bankswitching schemes to be added to the .bin files themselves, so future BIOS updates are not
necessary to support them.
