Advance Wars 1 won't save

Hi,
I downloaded Advance Wars 1 but it won't keep my save games, It says "Game Saved" but when I reload the rom it's not there.
I am using the latest version of VBA and all my other games save fine, I have tried all the available save types with both 64k and 128k sizes,
Any advice?
Thanks,
Tom

Maybe try changing the EEPROM and SRAM etc. options as well.

Those are save types

Yes but you can change both of those save options. EEPROM and Automatic list etc. You choose one of them. Then you choose either Flash 64 or Flash 128.
