* (3DS) Add bottom screen menu
-> User can save/load state on botom screen with thumbnail.
-> Call a save_state_to_file() when RAM state has data to write a disk.
-> If the bottom screen needs updating, swap the bottom framebuffers.
Add: SAVE/LODE STATE TO RAM
-> This is useful for devices with slow I/O
-> 3DS bottom save state use CMD_EVENT_SAVE_STATE_TO_RAM
-> 3DS bottom load state use CMD_EVENT_LOAD_STATE when RAM state has no data
-> 3DS bottom load state use CMD_EVENT_LOAD_STATE_FROM_RAM when RAM sate has data
* Rewrite path_get_state to retroarch_get_current_savestate_path
* Fix unterminated state_path
Set USE_CTRULIB_2=1 to build with libctru 2.0. When unset, this code
is compatible with the older toolchain.
Some 2.0 changes addressed rare problems in earlier versions:
- Save / restore stack pointer for init / exit
Otherwise, it could be outside of the range we deallocate.
- Run aptMainLoop in the audio driver to react correctly to sleep events
Other changes for 2.0:
- Remove ninjhax1 -- requires outdated APIs that have been removed
- Switch from __sync_arbiter to syncArbitrateAddress
- Use implicit gxCmdBuf
- Use gpuPresentBuffer for double buffering
