  Support for battery-saved RAM. This file
  provides two routines:

  SaveBattRam()  - Saves the battery-saved RAM
  LoadBattRAM()  - Loads the battery-saved RAM

  The battery-saved RAM is stored in the
  MemoryBankedRAM(0 TO 2097152) table. Battery
  support can be checked in RomInfos.Battery
  (0=No battery ; 1=Battery), and RAM size can
  be checked via RomInfos.RamSize (in bytes).

  zBoy is saving the content of battery-saved
  RAM in a specific (platform-dependant) location.
