v14
- Adds new UI for full remapping of E1 / E2 / E3 / E4 buttons - see "Configure Gamepad" menu.
- Due to this, "Swap buttons 8/9" and "Start and Select" options have been removed as they are now superseded.
- Fix small bugs with saving to a "clean" board
Note: some anti-virus software may flag the configuration tool as a trojan. You can just override it; it is a common false-positive among anti-virus software to flag applications packaged with pyinstaller. If you don't trust me, you can run from source yourself.
