EEPROM
Kirby 64 uses a 512 byte EEPROM chip to store save data. Software mirrors of the data are kept at 0x800EC9F8 and 0x800ECBB0 in RAM.
High level structure

Debug Cheat Code
It is possible to get a file with 100% completion using the function at 800BA5C4 with A0 set to the file you want to complete. This can be done in the vanilla game using a cheat code. Requirements:
- A second controller
- File 2 must be deleted
- File 3 must be initialized (but not yet started)
Steps:
- Reset the game
- Wait until the HAL Laboratory logo shows up
- Hold L on the second controller
- Press the button combo: C-up, C-up, R, C-right, C-left, Start.
- File 3 should be 100% completed now.
