heres something from way back on these forums...
1.11. I have a Japanese Neo CD system and want to use the Memory Card Manager,
what do the menu items mean?
While in the memory card manager, press A to activate an item, press A
again to confirm any action (e. g. deleting, formatting) and press B to
go back one step.
The menu items are:
1. Backup Memory Format
Use this to format your NGCD game save memory. Caution: ALL data will be
lost after formatting! If you have a brand new NGCD, you have to format
the game save memory once before you can use it, so if you think you have
a new console and can not save your games, format the memory first and
then try again.
2. Display Data Name
Shows the contents of the save memory.
3. Delete A Data
Delete game saves. Press A to select an item, press A again to confirm
deletion, press B twice to return to main menu.
4. File User's Name
Change the name of a game save.
5. End
Exit to CD player screen.
