Greetings,
I have an application for the GBA which needs to save data in the
battery backed SRAM at 0x0E000000. It saves OK on an older 64M flash
advance card when the power is removed so the code seems to work. A
256M card and a new flash2advance 64M card lose the data when power
is cycled. I am wondering if there is some kind of page register that
needs to be set in the newer cards to support different
save data banks for multiple game loads. The battery checked OK on
the 256M card. This app is the only program loaded in the cartridge
and it uses about 6K of SRAM. Any corruption would look like it
lost it too since my data checksum would fail. Does anyone have an
idea what might be
going
on?
Thanks,
