Im using an m3 real and with isakureal (sakura while playing so far). Looks like if Im playing a game and shut the lid, power is still being consumed. Do any of the flash carts (or is it a firmware feature which would mean I have hope), support power saving when the lid is shut?

 

the game does pause. But power consumption seems quite high

 

CycloDS has a battery saver feature no one knows how it works but it saves a decent amount of power
