I would say it's more or less only the linker script that will have to
be changed:

firmware/player.lds:

MEMORY
{
    DRAM : ORIGIN = 0x09000000, LENGTH = 0x200000 <----- here (0x800000)
    IRAM : ORIGIN = 0x0f000000, LENGTH = 0x1000
}

and

     .mp3buf :
     {
         _mp3buf = .;
     } > DRAM

     .mp3end 0x09200000 - 0x300: <---- here (0x09800000)
     {
         _mp3end = .;
     } > DRAM


Regards,

Vladimir
