An SD2IEC cannot emulate cartridges and is therefore unsuitable for Briley Witch Chronicles. You either need a device that can emulate EasyFlash cartridge or a real EasyFlash cartridge. Solutions for cartridge emulation are 1541 Ultimate II+, Backbit or Kung Fu Flash. If you want a dedicated EasyFlash cartridge for the game, that you can plug into your C64 and go, you are welcome to contact me.
