Similar to reading from a Pak, the write command is followed by two bytes for the address and checksum. But 32 bytes are also provided for writing to the Pak. The controller is still required to respond with a CRC byte for the received data, and it must begin responding within about 62.5 microseconds.
How the Pak interprets the address and data is up to the Pak in question. The Controller Pak
=== 0x04 - Read EEPROM Block ===
Line 244 ⟶ 246:
# Read the new RTC time.
# If the new time is within a second of what was written: write back the original time, success; otherwise failure.
=== 0x13 - Read from Game Boy Pak ===
Works identically to [[#0x02 - Read Controller Accessory|0x02 - Read Controller Accessory]], down to the address and data CRC, except that it reads from the Game Boy Pak which contains a MBC4 memory controller which supports JoyBus communication through the Nintendo 64 Controller port.
=== 0x14 - Write to Game Boy Pak ===
Similar to the previous command, this works identically like [[#0x03 - Write Controller Accessory|0x03 - Write Controller Accessory]], except that it writes to the Game Boy Pak.
