v1.2.1

Added

• Added an error message when a required binary was not found.
• Added check to ensure the Title and Publisher have at least one alphanumerical character to stop using
  vague details like - or ... e.t.c.
• Added error messages when a value from NACP was empty/unavailable and one was not manually specified.

Changed

• NTON now checks if the NRO path you provide is on your Switch microSD card by looking for Nintendo & switch
  folders, or atmosphere & bootloader folders. This is much more reliable than simply assuming any drive that
  isn't the C drive to be your microSD card.
• The NRO path is no longer forced to be within /retroarch/cores when --rom is used. This is to allow use of
  --rom with other Homebrew, e.g., MGBA.

Fixed

• Fix loading of prod.keys from the ~/.switch folder due to incorrect file-exists checks.
• Exiting from the Homebrew via the B button or an Exit option no longer crashes. The ExeFS ROM was updated by
  @Skywalker25 to support this feature properly.
• Fixed crashes when launching forwarders if the ROM path had any spaces.
• Fixed edge-case of incorrect sdmc path calculation on some Windows machines where the drive letter being replaced
  with sdmc:/ failed causing forwarders to crash on launch.
