I can not record the game with DUO-R.

[masuo]

Hello. I am a Japanese game user.
First please forgive my funny English.
I can not save the game with my DUO - R.
From an acquaintance, it was useless to tell me to replace the "super capacitor" and do it.
Just by resetting the game once with run and select all data will be lost.
When trying out the Tennokoe2, I get a message saying "I do not have backup memory".
I thought that the SRAM is broken,  [-o<I tried exchanging the SRAM (SRAM LC 3517 BML - 15 of SANYO).

But the matter does not improve. I feel SRAM is not recognized by the main body or Hu card slot.
Does anyone know such symptoms?
I would like you to help me.

Have you re-formatted the backup RAM yet?

[masuo]

Yes.
It is formatted with the item that comes out in the select on the first screen.
But it is useless.
