can we save the ram at a spot we like in armbian pi, like if im in a game, and than just when I restart the pi refill the ram with what it had so it can boot the game instantly?

sounds like standby or hibernate in Windows terms. Why do you need that?

yeah like system resume, well that would mean good boot time for the games I script if I got that. No one wants to wait the pis stock boots. The only pi's that boot faster when I remove all of the files from an orange pi etc directory,but that's because I wont be needing those important files for the os.
