64DD/Commands
< 64DD
Command List
Some commands are only available in either Retail, Development or Writer 64DD drives. All commands past 0x20 are considered hidden, and require the use of Command 0x50 to unlock them. Further verification will need to be done as it is entirely dependent on the firmware ROM in the H8/300 CPU inside the 64DD.
