This release features many substantial Game Boy emulation improvements
(all courtesy of Jonas Quinn), a new audio DSP class, and BPS patching
support.
Changelog (since v081):
- added new DSP audio engine; supports sample-averaging for the Game
Boy's high frequency rate
- GB: MMM01 images with boot loader at bottom of ROM can now be loaded
- GB: EI is delayed one cycle; fixes Bubble Bobble [Jonas Quinn]
- GB: fixed window -7 offset behavior; fixes Contra 3 first boss [Jonas
Quinn]
- GB: disable LCD interrupts when rendering is off; fixes Super Mario
Land 2 [Jonas Quinn]
- GB: fixed noise channel LFSR; fixes Zelda: LA lightning sound [Jonas
Quinn]
- GB: square channels use initial_length like the noise channel [Jonas
Quinn]
- UI: added BPS patching support; removed UPS patching support
- UI: when loading BS-X/Sufami Turbo/Game Boy games; display game title
instead of BIOS title
- UI: modified timestamps on screenshots for Windows/NTFS (which
disallows use of ':')

Finally, a new release. I have been very busy finishing up SNES box,
cartridge and PCB scanning plus cataloguing the data, however this
release still has some significant improvements.
Most notably would be randomization on startup. This will help match the
behavior of real hardware and uninitialized memory + registers. It
should help catch homebrew software that forgets to initialize things
properly. Of course, I was not able to test the complete library, so it
is possible that if I've randomized anything that should be constant,
that this could cause a regression. You can disable this randomization
for netplay or to work around any incompatibilities by editing bsnes.cfg
and setting snes.random to false.
The GUI also received some updates. Widget sizes are now computed based
on font sizes, giving it a perfectly native look (because it is native.)
I've also added a hotkey remapping screen to the input settings. Not
only can you remap inputs to controllers now, but those who did not know
the hotkey bindings can now quickly see which ones exist and what they
are mapped to.
Changelog (since v077):
- memory and most registers are now randomly initialized on power-up
- fixed auto joypad polling issue in Super Star Wars
- fixed .nec and .rtc file extensions (they were missing the dot) [krom]
- PPU/accuracy now clears overscan region on any frame when it is
disabled
- PPU/compatibility no longer auto-blends hires pixels (use NTSC filter
for this)
- added hotkey remapping dialog to input settings window
- added a few new hotkeys, including quick-reset
- phoenix API now auto-sizes widgets based on font sizes
- file dialog once again remembers previously selected file when
possible

Most notable in this release is that sound support has been added to my
own Super Game Boy emulation. The GUI toolkit, phoenix, has also
received a complete rewrite; with the most visible change there being
that windows are now resizable.
Changelog (since v075):
* added sound emulation to Game Boy core
* fixed Super Game Boy save state
* support added HexEdit widget to Windows and Qt targets; debugger can
now be compiled on all platforms
* entering fullscreen now auto-hides mouse; and mouse capture is toggled
otherwise by F12 key
* fullscreen command and geometry caching works much better on GTK+ and
Qt targets
* phoenix rewritten from scratch; now supports resizable layout
containers
* phoenix/Windows no longer relies on buggy SetParent API to reparent
widgets

This release marks a major step forward, offering full low-level
emulation of all four DSP coprocessors based on the NEC uPD77C25
processor core. Many people were responsible for this milestone: Dr.
Decapitator for the actual decapping and extraction; Lord Nightmare for
the cartridges and some special analysis tools; myself, Jonas Quinn and
Cydrak for the uPD77C25 emulation; and all of the donors who raised the
necessary $1,000 for the necessary hardware and equipment needed to pull
this all off. To say thanks to the donors, I am releasing the uPD77C25
emulation core to the public domain, so that everyone can benefit from
it.
All four DSP emulations will be improved by this by way of having
realistic timing; the DSP-4 will benefit further as the high-level
emulation was incomplete and somewhat buggy; and the DSP-3 will benefit
the most as the high-levle emulation there was not complete enough to be
playable. As a result, most notably, this means bsnes v073 is the first
emulator to fully be able to play SD Gundam GX (J)!
As bsnes' primary goal is accuracy, the LLE DSP support renders the old
HLE DSP support obsolete. Ergo, I have removed the 166KB of HLE source
code, and replaced it with the uPD77C25 core, which comprises a mere
20KB of source code. As this LLE module supports save states, this also
means that for the first time, DSP-3 and DSP-4 games have save state
support.
On the other hand, this also means that to run any DSP game, you will
need the appropriate program ROM. As these are copyrighted, I cannot
distribute them nor tell you where to get them. All I can do is provide
you with the necessary filenames and hashes.
Changelog (since v072 release):
* added NEC uPD77C25 emulation core
* added low-level emulation of the DSP-1, DSP-1B, DSP-2, DSP-3, DSP-4
coprocessors
* removed high-level emulation of the DSP-n coprocessors
* added blargg's libco::ppc.c module, which is far more portable, even
running on the PS3
* added software filter support via binary plugins
* added debugger (currently Linux-only); but it is as yet unstable
* added pause shortcut
* updated mightymo's cheat code database
