I can't see any excel file O_o...could you link me the actual download?
As for your EZ-Flash problem when you start up the flash cart in the initial start up it asks your to Hold L to skip saving or something like that, I ALWAYS hold L to skip. Try doing that see if you get it to work. Otherwise I'll have to go back and check what it is exactly I'm doing to keep the Save File. Did you check the names as well? Sometimes the slightest difference can be missed in the name of the ROM and Save file, make sure they're exactly the same. I know there's a solution since I had the same issue when I first got the EZ-Flash drive, it's just been so long I forgot what it is exactly I did to resolve the problem O_o...
