Update to bsnes v028 release.
Changelog:
- OpenGL (with hardware filter mode support) and SDL video drivers added to Linux port
- OpenAL (with speed regulation disable support) and OSS audio drivers added to Linux port [Nach]
- SDL input driver (with joypad support) added to Linux port
- Emulator pause option added
- Added option to select behavior of bsnes when idle: allow input, ignore input or pause emulator
- Added support to remap common GUI actions to key/joypad presses on the "Input Configuration" screen
- bsnes will now clamp the video output size when it is larger than the screen resolution
- GUI library has been enhanced, and renamed to hiro
- Fullscreen mode now always centers video, rather than approximates
- Fullscreen mode now works correctly on Linux/Openbox
- Extra layer of abstraction in src/ui has been removed, as GUI lib unifies all ports anyway
- Video, audio and input drivers unified into standard library, named ruby
- All custom headers have been merged into a new template library, named nall
- Makefile rewritten, vastly improved. Allows quick toggling of compiled-in drivers
- Makefile: all object files now placed in /src/obj, binary placed in /
- libco greatly enhanced, no longer requires an assembler to build [byuu, blargg, Nach]
- libco SJLJ driver added; bsnes should now build on any Unix-derivative now (Solaris, OS X, PS3, etc) [Nach]
- Fixed register $213e.d4 PPU1 open bus behavior [zones]
- Windows port will not activate screensaver while bsnes is running [Nightcrawler]
- Visual C++ target no longer requires stdint.h
- And lots more -- mostly code refactoring related

|
|
|
WARNING: the overhead of POSIX ucontext is very high,
|
|
|
|
assembly versions of libco or libco_sjlj should be much faster
|
|
|
|
|
|
|
|
this library only exists for two reasons:
|
|
|
|
1: as an initial test for the viability of a ucontext implementation
|
|
|
|
2: to demonstrate the power and speed of libco over existing implementations,
|
|
|
|
such as pth (which defaults to wrapping ucontext on unix targets)
|
|
|
|
|
|
|
|
use this library only as a *last resort*
