Hacking is SAVING possible after battery inside the Supercard dies?

[blueagent004]

is it true that when the save battery inside the gba supercard dies, you can no longer SAVE game progress?

i've always thought that the gba supercard uses SAVE-RAM to write the save file to the microSD card, and that the battery inside the gba supercard is only used for games that has an internal clock, or something like that....is this not the case after all?

thanks for letting me know!

The Supercard Mini SD does not have a Real Time Clock.

It uses SRAM for savegames and SRAM is volatile memory - it requires power to remain it's data, that's what the battery is for. I am not very familiar with how the SC handles copying the savegame from SRAM to the SD card but my guess is that you have to power the system off and on again to initiate the copying process. If that's the case the SRAM is temporarily without power and loses it's contents. I.e.: savegame's gone.

I have a Supercard minisd but I don't use it much anymore.
I think there is a key combo to dump SRAM to SD card immediately.

Save in your game, then press L R A Select to backup your save.
"backup" means copy the contents of SRAM to gamename.sav on the SD card.
