Hacking Supercard Lite (micro) save problem

[Gagarin]

Ok. So I hace that Supercard Lite. New firmware. Some GBA games don't work, but problem is with saves. I played the game, save and next day the save was gone!
So I tried again - same thing. What's wrong with it!
Why it's not like normal Slot 1 card. You save and you can use it anytime.
Help! Without saves this card is kinda useless for me....

Go to the English Supercard site and read the FAQ. It will tell you what you must do to save GBA games correctly.

Yeah, that helped.
But still I can't save in Mother 3.
I approached the frog, try to save but it says "unable". What to do?
