Using EEPROM on Teensyduino or TeeOnArdu (Leonardo)

Hi to everyone. I've made a MIDI controller using a Leonardo whith another bootloader following this: GitHub - fricklr/TeeOnArdu
In the board select menu I select "TeeOnArdu".
Everything works OK but now I'm trying to use the EEPROM library and it seems to be disabled when I select this board. If I go and choose Leonardo as the board, the include->EEPROM option appears again.

Is there a way to use the EEPROM library when using the Leonardo as a TeeOnArdu? OR using EEPROM without library? (I believe this would be too hard anyway)

Thanks in advance!

type #include <EEPROM.h>

MalharD:
type #include <EEPROM.h>

I am having the same issue as the original poster, and that didn't work. The EEPROM library seems to be inaccessible when using this type of board.
