128k memory: saving and restoring data

[oblo]

Hi all

I'm trying to program a game for the +2A/+2B/+3, so I can use more RAM. Thanks to a lot of info I found on the forums, I manage to access all memory banks with this:

Code:

asm
  di
end asm

poke 23388,16 + bank_number : OUT 32765,16 + bank_number

asm
  ei
end asm

Question is, I don't know how to efectively save and retrieve data in the 45152-65535 address range. I prepared some programs just with data arrays, saved with something like SAVE "databank6" CODE 49151,16384 and then load it from the main program but no data is restored, so I assume I'm doing it wrong and saving no data at all.

How can it be achieved? Thanks in advance an regards.
