EZ-Flash Junior load game issue

Hi,

I have EZ-Flash Junior with 4GB MicroSD format FAT32 with 32kb cluster, I can get into the menu and I am on FW4 K1.04e
But I can't load the same and all the game list showing as upside down e.
I have changed the game name to simple zelda.gbc but it's still showing upside down e character.
Any idea? help.
