Gen3 Joey Firmware Update

Regular price $10.00

Stock: 947

Beta testing complete. Available NOW!

Firmware Version V2_02_34

We have spent the last 2 weeks porting and testing our Joey Jr firmware on the Gen3/Gen3 mini hardware platform.

Support is very close to the Joey Jr. These are the things we couldn't port over due to CPU and Hardware limitations

  • MBC30 DIY cart cannot be flashed reliably
  • Bootlegs which use 1.8volt flash and no diode may fail to flash reliably (The 1.8v carts we've tested all passed)
  • Speed decrease ~25% under the Joey Jr
  • No auto-voltage switching for 3.3v bootlegs

Benefits over the existing 3_xx Gen3 firmware

  • 5x+ faster flashing & dumping of GB/GBC/GBA bootlegs
  • Supports all the latest bootleg carts assuming 3.3v flash or above
  • Bootleg/Fake detection
  • Supports NPC carts
  • Supports Multi-ROM carts
  • Supports InsideGadets Flash Carts
  • Supports 256Mbyte GBA Video Bootleg carts
  • Drag and Drop - No software - No drivers
  • Can be connected to your smart phone (USB OTG required, FAT12/16 support required - Almost all Android phones)

Things you need to know:
