scoopbls - you sure you understand exactly what he is saying?
it's obvious that the saves are stored on microsd, but he is asking whether the saves are backed up to microsd from the battery on reboot, or directly written to microsd during gameplay...
then again you might have understood it perfectly, wherby i will apologise.
You get it pretty close, I want to know if there is a way (and QPC doesnt count) that I can write games saves directly to the MicroSD while playing, not after its rebooted. And a way to prevent the auto backup on reboot.
When the battery eventually dies, this would make the difference between a usable device, or an expensive paperweight.
The auto backup needs to be prevented because it would overwrite your manual save, and if the battery is dead, it will do so with a blank save.
Having a battery save is a nice idea to remove the need for complex button combinations to save. But its fundamentally flawed because of its finite nature. I have been burned in the past by all sorts of cartridge based games that had their batteries die prematurely, and I need to know that I will still be able to use this cart after that happens.
