Update to v094r38 release.

byuu says:

I'll post more detailed changes later, but basically:
- fixed Baldur's Gate bug
- guess if no flash ROM ID present (fixes Magical Vacation, many many
  others)
- nall cleanups
- sfc/cartridge major cleanups
- bsxcartridge/"bsx" renamed to mcc/"mcc" after the logic chip it uses
  (consistency with SGB/ICD2)
- ... and more!
