CartBoy is no longer under active development. I'd recommend using FlashGBX.

Thanks for all the support.

• Native macOS 🎉
• Quick transfer speeds 🚀
• Copy ROMs from your physical cartridges 📦
• Write ROMs to your own flash carts ⚡️
• Backup / Restore / Erase game save files 👾

CartKit is a companion framework, used by CartBoy, that defines general device support and functionality.

The SerialDevice<GBxCart> is the cart reader device from insidgeGadgetsController that is capable of the following:

• Reading the cartridge header; and,
• copying the cartridge ROM; and,
• backing up save data (if supported); and,
• restoring save data (if supported); and,
• deleting save data (if supported); and,
• flashing new ROMs to compatible cartridges; and,
• erasing existing ROMs from compatrible cartridges.

A SerialDevice<GBxCart> cannot be instantiated directly; instead use open on GBxCart and you'll receive an isntance.

Simply open a SerialDeviceSession, then read the header (checking the Result):

GBxCart.open { serialDevice in
  switch serialDevice.header(forPlatform: GameboyClassic.self) {
  case .success(let header) :print(header)
  case .failure(let error)  :print(error)
  } 
}

Some functions let you get updates on the progress of an operation (such as when copying a cartridge to your Mac). In these cases you must call the operation from queue other than the main one.

If you omit providing a progress callback, the operation blocks the main thread; this maybe useful for a number of scenarios (such as unit tests).

GBxCart.open { serialDevice in
  try {
    let cartridge = serialDevice
       .readClassicCartridge (progress: { print($0.fractionCompleted) })
       .write                (toDirectoryPath: "/Users/kevin/Desktop")
       .check                (MD5: "b259feb41811c7e4e1dc20167985c84") /* Super Mario Land? */
       .get()
     print(cartridge)
  } catch {
     print("\(error)")
  }
}
