349e47f0b2 Small fixes to division by zero 
This causes crashes in PSP quite often in many games. Other CPUs might
(depending on the processor state) silently return zero or some
undefined value.
The fix is borrowed from ReGBA's codebase

f8b598a2ed Update RTC emulation

d8225bb313 Add optional battery save using libretro save api 
- Adds core option to allow battery saves using the libretro api
  (retro_get_memory_data/size)
- Initial save size set at 128KB and actual size is automatically
  determined internally by gba.
- This will always assume that a save file is supported since save
  size or type cannot be determined until gba tries to write to backup memory.
- A 128KB block of memory is used as buffer, similar method to VBA
  Next/Beetle GBA workarounds.
