And out from left field, comes a SNES9x release! With alot of improvements and tweaks. There is a Windows port this time, and Netplay has been reworked. This version also supports NSRT headers.

Whats new for 1.51:

• Added DSP1 and SuperFX savestate support. (nitsuja)
• Added screen state GFX to save states. (optional) (nitsuja)
• Fixed desync when loading inconsistent state in playback. (nitsuja)
• When playback reaches a movie's end, recording continues instead of the movie suddenly closing. (after recording) (nitsuja)
• can now record resets and mouse/superscope/justifier(s) (nitsuja)
• Added same-line-comment support for config files. (nitsuja)
• input display for all controllers (including peripherals) (nitsuja)
• Win32: Now uses .cfg file instead of Windows registry. (nitsuja)
• Win32: open ROM dialog bugfixes and speedup and facelift (nitsuja)
• Win32: option to use standard file open dialog for ROMs (nitsuja)
• Win32: maintain aspect ratio and bilinear filter stretch (nitsuja)
• Win32: optional removal of the dreaded "black bar" (nitsuja)
• Win32: Added EPX,EPX2,EPX3,HQ2X,HQ3X,TV3X,DM3X filters. (nitsuja)
• Win32: Added hires support for Interlace and TV Mode. (nitsuja)
• Win32: text removed from .avi output (optional) (nitsuja)
• Win32: better directory management, customizeable (nitsuja)
• Win32: Screenshot support is back. (nitsuja)
• Win32: Netplay is back (but still not very good). (nitsuja)
• Win32: Made OpenGL Bi-linear an advanced .cfg option. (nitsuja)
• Win32: cheat search improvements (address, watch, SuperFX)(nitsuja)
• Win32: Added non-modal ("active") cheat search option. (nitsuja)
• Win32: new hotkey-config dialog and configurable hotkeys (nitsuja)
• Win32: Fixed joystick config in input dialog. (nitsuja)
• Win32: Fixed hires and extended height .avi output. (nitsuja)
• Win32: various small GUI improvements (nitsuja)
• Win32: Netplay fixes. (nitsuja)
• "Fake Mute" desync workaround option for movies, until all ports have deterministic sound. (Bisqwit, nitsuja)
• Fix for save state blocks > 999999 bytes. (Bisqwit)
• C4 games now save C4 data in save states. (DeHackEd)
• Unix: Framework for high-speed seeking. Specify a frame number in a movie, and the emulator will run at maximum speed to that frame. Untested. (DeHackEd)
• X11: Support for window exposure. When a window is damaged due to overlay, being iconified, etc. it will be repainted correctly. (DeHackEd)
• Unix: parameter: -autodemo loads a movie for playback on startup. Only the x11 code handles this right now. (DeHackEd)
• Unix: parameter: -oldturbo, the turbo button renders all frames when fast-forwarding. (DeHackEd)
• Unix: parameter: -upanddown, override U+D and L+R protection. (DeHackEd)
• Unix: parameter: -mute, currently linux only, blocks out audio output from your speakers while still emulating sound. Not fully tested. (DeHackEd)
• Unix: parameter: -maxframes during movie playback, snes9x will exit when the target is hit. (DeHackEd)
• Unix: parameter: -keypress shows to stderr and on-screen the currently pressed buttons on joypad 1. (DeHackEd)
• Unix: Stream dumping (NOT COMPLETE). With -dumpstreams, raw video and raw audio are dumped to videostream%d.dat and audiostream%d.dat, where %d increments on each CPU reset, starting at zero. (DeHackEd)
• Unix: Non-blocking sound on Linux. It makes seeking nicer.(DeHackEd)
• Unix: Configurable sound device. (pierredavidbelanger)
• configure.in now requires a sufficiently new version of autoconf. (anomie)
• Fixed slow versions of branch opcodes. (anomie)
• Fixed the mosaic offset bug. (anomie)
• No sorting by priority in C4 command 00 00. MegaMan X2 can go behind the legs of the intro stage boss. (anomie)
• New RTO discovery, fixes Super Conflict: The Mideast title screen. (anomie, byuu)
• A 1->0 transition on $2100.7 causes OAM Address Reset. (anomie, byuu)
• The final HDMA Indirect Address load is only weird on the last channel of the scanline. Touge Densetsu Saisoku Battle problem solved. (anomie, byuu)
• Fixed BGnVOFS bug. Only HOFS needs ~&7 update. (byuu)
• Fixed superfluous VIRQ triggers. (zones)
• Fixed missing IRQ trigger just after the previous one. (zones)
• Fixed missing IRQ while writing to $4200. (zones)
• Fixed IRQ timing after WRAM refresh. (zones)
• Fixed NMA timing after DMA transfer. (zones)
• Fixed superfluous auto-joypad-reading. (zones)
• Fixed missing WRAM refresh during DMA transfer. (zones)
• Fixed DMA so that HDMA and any HC triggered events can run during DMA transfer. (zones)
• Roughly fixed the case that HDMA and DMA use the same channel at the same time. HDMA kills DMA. Thanks byuu. (zones)
• Changed initial DMA registers values. (zones)
• Slightly modified APU execute timings. (zones)
• Fixed APU I/O registers to get/set the proper value. (zones)
• Blocked invalid VRAM writings, though you can turn off this option due to Snes9x's inaccurate timings. (zones)
• Omitted SPCTOOL, no one uses it. (zones)
• Added Sufami Turbo support. (zones)
• Added Same Game add-on cart support. (zones)
• Fixed HiROM SRAM and DSP1-4 memory maps a little. (zones)
• Improved mirroring. (Nach, grinvader, byuu)
• CRC32 on BS dumps now follows uCONSRT standard. (Nach)
• BS dumps now always run in NTSC mode. (Nach)
• Unknown regions (generally betas) default to NTSC. (Nach)
• Now support NSRT headers for setting up controllers. (Nach, nitsuja)
• Unix: Fixed command line help output. (Nach)
• Unix: Sound now defaults to 32KHz, Stereo, Interpolation so Snes9x finally sounds like a real SNES by default. (Nach)
• Win32: Saner defaults for movie record. (Nach)
• Unix: Fixed crashing with mouse or super scope. (Nach)
• Removed some weird code which was crashing Korean League and its varients. (Nach)
