bsnes v0.048 - 模擬器

http://byuu.org/bsnes/

The biggest feature of this new release is the addition of save state
support. Note that this is only currently supported for normal games, and the
SPC7110 and OBC-1 co-processors. Other special chips, such as the SuperFX and
SA-1, cannot currently save and load state files. I will be adding support
for other co-processors little by little in future releases.

Changelog:

Added save state support

Added SPC7110 and OBC1 save state support

Added new tools group, with new cheat code and save state managers

Lots of new UI shortcuts: quick save state, quick load state, show state
manager, etc

Escape key will now close both the settings and tools group windows

Added major speed-ups to both SuperFX and SA-1 emulation; both now run
~15-25% faster than v047

Added new video filter, LQ2x; it′s as fast as Scale2x while being almost as
smooth as HQ2x

Re-wrote HQ2x algorithm; code size was reduced to less than 10% of its
original size with virtually no speed loss

Corrected SuperFX2 cache access timing; fixes Stunt Race FX menus and
slowdown in other titles

Relaxed palette write limitations for PGA Tour Golf [Jonas Quinn]

Fixed a slight timing issue that was breaking ′An Americal Tail - Feivel
Goes West′

Turned off auto-save of SRAM as it was causing slowdowns when writing to
flash memory; can be re-enabled via bsnes.cfg -> system.autoSaveMemory = true

Added bsnes.cfg -> system.autoHideMenus, defaults to false; when true, menu
and status bars will be hidden upon entering fullscreen mode

Added skeletons for ST011 and ST018 support. Both Quick-move titles get
in-game now

Re-wrote S-CPU and S-SMP processor cores to use templates, removed custom
pre-processor

Split PPUcounter into a base class inherited by both PPU and CPU; allows both
cores to run out-of-order

Split inline header functions to separate files, allows headers to be
included in any order now
