Populating persistent memory

How do i populate persistent memory?
is it like lowres original where there is a dedicated command or do i have to do some poke and peek voodoo to it?

Voodoo! ;)
It’s just an area in the memory map (see manual).

See chapter “Hardware Reference” -> “Memory Map”/“Persistent Memory”

One "trick" i have used is to "store" variables to the background, save both backgrounds to PERSIST memory, then reload the backgrounds and manually read the data off the backgrounds... i will post an example....

Actually, its the example is going to be a mini game... here is a sneak peak...

I will finish and post the example/game later in a few hours... :)

How do you do multiple saves I’ve tried before but when I load the numbers there all distorted by doing PEEKL($E001) I’ve tried using a number splitter I made but I gave up

TrashCan, you could use different offsets.
NSAVE=0
OFFSET=$E000+NSAVE*64
SCORE=PEEKL(OFFSET+0)
LIVES=PEEKL(OFFSET+4)
ARMOR=PEEKL(OFFSET+8)
ATTACK=PEEKL(OFFSET+12)

NSAVE is the save number/slot.
By multiplying this by 64 you get space for 16 long numbers. This value can be adjusted.
