- 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 <filename> 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)

audio output from your speakers while still emulating
sound. Not fully tested. (DeHackEd)
- Unix: parameter: -maxframes <target> 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)

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 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)
