You shouldn't need to change the serial port speed from the 38400 bps default, but if you experience connection stability issues, feel free to change it to 9600 bps.

To create a console IPL / boot ROM backup:

1. Initiate an XMODEM download on your PC.
2. Select the Transfer IPL… option.
3. Wait for the XMODEM download to finish.

To create a cartridge backup:

1. Select the Cart Backup… option.
2. Ensure that the cartridge configuration (ROM, SRAM, EEPROM size; ROM access width, speed) is correct.
   • The tool will try to auto-detect cartridge configuration based on its header. Most of the time, you should not need to change any option.
3. Initiate an XMODEM download on your PC.
4. To back up cartridge data, select Backup ROM…. To backup up save data, select the Backup SRAM…, or Backup EEPROM… option, depending on cartridge.
   • Most cartridges will only have SRAM or EEPROM, but not both.
5. Wait for the XMODEM download to finish.

To restore cartridge save data from a backup:

1. Select the Cart Restore… option.
2. Ensure that the cartridge configuration (SRAM, EEPROM size; ROM access width, speed) is correct.

4. Initiate an XMODEM upload on your PC.
5. Wait for the XMODEM upload to finish.

To erase cartridge save data:

1. Select the Cart Erase… option.
2. Ensure that the cartridge configuration (SRAM, EEPROM size; ROM access width, speed) is correct.
   • The tool will try to auto-detect cartridge configuration based on its header. Most of the time, you should not need to change any option.
3. Select the Erase SRAM…, or Erase EEPROM… option, depending on cartridge.
4. Wait for the erase process to finish.
