Hi all, I made the battery mode on this board (replaced the rechargeable battery with a coin CR2032).
The backup RAMs and other chips are getting the 3V from the battery when the power is off.
But it is not working entirely fine.
I mean, after power off and on, the RAM will maintain some data but will delete some other.
For example:
1) the calendar date is not erased
2) the board enters in console mode (if the backup RAM wasn't working, the system will boot as arcade).
So far so good.
But the hiscores on the game are not saved, as well as some configuration options (like the blood on metal slug).
Any ideas? Maybe only one of the 2 RAMs is faulty?
