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*

#define LIBCO_C
Update to bsnes v029 release. A new version of bsnes has been released. It contains a few minor emulation fixes, as well as user interface improvements. Behind the scenes, the source has been cleaned up more in preparation for running the CPU and PPU (video processor) separately from each other (eg with no enslavement.) This is required for implementing a clock cycle based PPU renderer. - Greatly improved invalid DMA transfer behavior, should be nearly perfect now - Major code cleanup -- most importantly, almost all PPU timing-related settings moved back to PPU, from CPU - Added option to auto-detect file type by inspecting file headers rather than file extensions - Rewrote video filter system to move it out of the emulation core -- HQ2x and Scale2x will work even in hires and interlace modes now, 50% scanline filter added - Re-added bsnes window icon - Added new controller graphic when assigning joypad keys [FitzRoy] - Redundant "Advanced" panel settings which can be configured via the GUI are no longer displayed - Improved speed regulation settings - XP and Vista themes will now apply to bsnes controls - Added "Path Settings" window to allow easy selection of default file directories - Tab key now mostly works throughout most of the GUI (needs improvement) - Main window will no longer disappear when setting a video multipler which results in a window size larger than the current desktop resolution - Added two new advanced options: one to control GUI window opacity, and one to adjust the statusbar text

Update to v103r21 release. byuu says: Changelog: - gb: added TAMA emulation [thanks to endrift for the initial notes] - gb: save RTC memory to disk (MBC3 doesn't write to said memory yet; TAMA doesn't emulate it yet) - gb: expect MMM01 boot loader to be at end of ROM instead of start - gb: store MBC2 save RAM as 256-bytes (512x4-bit) instead of 512-bytes (with padding) - gb: major cleanups to every cartridge mapper; moved to Mapper class instead of MMIO class - gb: don't serialize all mapper states with every save state; only serialize the active mapper - gb: serialize RAM even if a battery isn't present¹ - gb/cartridge: removed unnecessary code; refactored other code to eliminate duplication of functions - icarus: improve GB(C) heuristics generation to not include filenames for cartridges without battery backup - icarus: remove incorrect rearrangement of MMM01 ROM data - md/vdp: fix CRAM reads -- fixes Sonic Spinball colors [hex\_usr] - tomoko: hide the main higan window when entering fullscreen exclusive mode; helps with multi-monitor setups - tomoko: destroy ruby drivers before calling Application::quit() [Screwtape] - libco: add settings.h and defines to fiber, ucontext [Screwtape] ¹: this is one of those crystal clear indications that nobody's actually playing the higan DMG/CGB cores, or at least not with save states. This was a major mistake. Note: I can't find any official documentation that `GL_ALPHA_TEST` was removed from OpenGL 3.2. Since it's not hurting anything except showing some warnings in debug mode, I'm just going to leave it there for now.
