DEBUG.TXT - spiritek/JoeyJrDocumentation GitHub Wiki

Displays debug information, like current firmware version, type of cart, and if the cart is able to be flashed

If you can flash the cart it will display "Flash Detected" otherwise it will display "No Flash Detected"

The Joey will also test to ensure the header is read correctly, if it detects any issues it will show the text "Checksum Invalid", the best solution for this is to clean the cartridge connector and make sure the cartridge is inserted correctly.

Example for original cart (Pokemon Ruby) :
