NOTICES:

• To flash this cartridge yourself, purchase a Joey Jr. HERE!
• If using a Joey Jr. to flash this cartridge yourself, you MUST update your Joey Jr. to the latest firmware, found HERE!
• A recent update has been applied to ALL BennVenn MBC3000 model flash cartridges that allows for greater compatibility with FPGA-based consoles, including the Analogue Pocket, ModRetro Chromatic, the FunnyPlaying FPGA "FPGBC" console, etc.; Use with GENUINE console hardware is still recommended, and full FPGA compatibility is NOT guaranteed.
• All aftermarket flash cartridges currently available (not just BennVenn) do not run properly on FPGA-based game consoles, so we recommend using GENUINE / ORIGINAL consoles for playing this flash cartridge!
• If you selected a "Flash my ROM (email us)" option above, please email us at support@highscoretech.com immediately after placing your order to let us know your FULL NAME and ORDER NUMBER, and to provide us your game ROM file/files (2 ROMs maximum; 4 MB max size for two, 8 MB max size for one).  THE ACTUAL GAME ROM FILE MUST BE SENT.  WE DO NOT AND CANNOT PROVIDE ROM FILES!  Thank you!
