Gaming Bootleg zelda minish cap save problem

[Sliter]

I know I'm not the first one but since my cart is a bit different so I'm creating a new thread ...
Well, I Just got minishcapcom bootleg (I knew it was) from aliexpress, and it's really are good looking, the plastic quality seems good, the label printing is very nice too and the color shell matched very nicely the game label, right?

But there was a problem, when I tried to play it ... when I get the file selection, came a message " save file is corrupt" or something alike,I tried to create a file on "File1", I was able to create and start the game, but when I turn the console off, the save get erased.
If I create one and go to " options" and save with different setting, it give a message of error and erase the save, If I try to create in any other file, it tell me that it could create the file.
I think it's should be different from these that came with an " AAAAA" save file issue.
I contacted the seller to see if he can do something for me, so lets see

But there are something I could do with this?
here a bad shot of the board, later I try get a better one :v
