Kirby no Pinball Battery Problem (READ FIRST)

[Alex4U]

Today i buy a Japanese, new, (and rare!) Kirby Block Pinball (JP) Its original, yeah, yeah...
BUT...!
The problem its the battery!
I Solder/ put a new a battery!
And works, but for example:
I Create a new game
(save)
turn off Gameboy
(Wait 5/10min.)
And THE SAVE IS GONE!
I Tried solder, put a new battery, and put another type of battery CR20XX, AND DOESNT WORK!
WHAT IS THE PROBLEM!
I PLAYED AND I WAS IN THE WORLD 5, AND MY SAVE IS GONE!

AND ITS NEW THE F***** GAME!
THANK YOU FOR YOU HELP.

I had this issue with a copy of Link's Awakening one time. Try reflowing the solder on the various chip connections and see if that solves the problem or if you somehow burned or broke a trace on the board. If these steps don't work, the board might be fried or something.
