[SFC] bsnes Update
bsnes v0.019.09 (WIP)[url]http://byuu.cinnamonpirate.com/?page=bsnes_news[/url] 2007-02-17 - S-DSP
With some logs from DMV27, and assistance from blargg, I was able to fix the final remaining sound bug in bsnes. KON/KOFF behavior was updated to correct sound effects when pausing in Toy Story. Though despite having no known bugs, I'll continue to attempt to improve the accuracy even further.
I also worked a bit more on the lui port of bsnes. Video mode selection is now possible. But I still really need an input configuration window (and not to mention, Linux input support) at the very least before I can make another release.
[url]http://byuu.cinnamonpirate.com/?page=bsnes_news[/url] bsnes v0.020 beta released
This is an early beta for the next release of bsnes. Please keep in mind that the new UI is not yet complete, so things are kind of minimal. This version should be a lot faster than the previous versions, but sound doesn't seem to be working right on some machines. If you get no sound, I apologize, this will hopefully be corrected in time for the next official release.
[url]http://byuu.cinnamonpirate.com/?[/url] bsnes v0.020
Added blargg's new S-DSP emulator, runs at 1.024mhz. Many thanks to blargg for this, as this puts all portions of SNES emulation except for the S-PPU at bus-accuracy
blargg's S-DSP core fixes bugs in both Koushien 2 (J) and Toy Story (U)
Corrected all S-SMP cycle timings to be hardware accurate. Thanks to blargg for creating an amazing test ROM that tested every possible opcode
Corrected S-CPU wai instruction timing, fixes Mortal Kombat II
Reverted HDMA sync emulation once more to fix Breath of Fire II (G) and Secret of Mana (U)
Completely rewrote user interface to use libui, which is a wrapper that allows the same code to produce the same UI on both Windows (through the Win32 API) and Linux (through the GTK+ API)
Corrected $2100.d7 OAM reset behavior, thanks to research from anomie
Massively revamped the Linux port, should compile with no warnings or errors now
Added 64-bit support to libco, tested on FreeBSD/amd64, should work on Linux as well
Revamped makefile with suggestions from Nach
Improved Linux Xv renderer to use the far more common YUY2 format, which should work on most Xorg drivers, allowing hardware accelerated video scaling
Completely rewrote config file system. bsnes.cfg is now saved to user's profile folder on both Windows and Linux, allowing multi-user support
A lot more work has been done behind the scenes, including massive code cleanups and portability improvements
[url]http://byuu.cinnamonpirate.com/[/url] bsnes v0.021 released
This is a maintainence release. I am mostly releasing this for the sake of the recently released Der Langrisser translation.
Changelog:
Windows port can once again map joypads through the Input Configuration panel

Fixed serious crashing error with File->Load on Linux/amd64 port
Hopefully fixed min/max undefined error on GCC 4.2.0, but I am unable to test to verify
Fixed many cast const char* to char* warnings for GCC 4.2.0, but some probably remain, as again, I am unable to test as I lack GCC 4.2.0
Set XV_AUTO_COLORKEY to 1 for Video/Xv renderer. Should fix some video drivers where there was no output, especially after running mplayer, etc. Thanks to sinimas for the fix
Added clear_video() to Video/Xv renderer. Green edges at the bottom and right sides of the video output are now gone, and unloading a ROM will clear video
[url]http://byuu.cinnamonpirate.com/[/url] bsnes v0.022 released
* Fixed buffer overflow that was manifesting as corrupted tiles in Lemmings 2
* OAM and CGRAM addresses are now invalidated during active display, however the algorithms for how this address invalidation occurs is currently still unknown, so reads/writes are mapped to static addresses for now

[url]http://byuu.cinnamonpirate.com/[/url] bsnes v0.032a released
Very sorry for the inconvenience. Some last minute bugs snuck into the last release.
Also, I've added three new localizations: French (by tukuyomi), Portugese - Brazillain (by Hunter) and Russian (by Hatsuyuki). Dutch, Finnish and German should follow shortly, so be sure to check back in a week or so if you'd like one of those.
I forgot to mention this on the last update, but for any sites hosting the bsnes executable, you are free to distribute the archive with any locale you'd like. In fact, I'd prefer if you did, as it makes it easier for those who cannot read English.
Changelog:
• Windows: file open filters are now working once again
• All ports: emulation speed setting is now properly restored at startup
[url]http://byuu.cinnamonpirate.com/[/url] bsnes v0.033
This release adds SPC7110 emulation, without the need for graphics packs!!, and a rewritten S-RTC (real-time clock) emulator.
SPC7110 support means that Far East of Eden Zero, FEoEZ: Shounen Jump Edition, Momotarou Dentetsu Happy and Super Power League 4 are now all fully playable. I will warn you, the emulation is very slow in this version -- while most areas of each game will run at the same speed as other games, there are a few peak moments where speed will drop by up to ~50%. The reason for the slow-down is that I am currently uncertain how to determine the amount of data to decompress in advance, so I default to the maximum amount possible. The reason I am releasing now anyway, is because I beleive in the "release early, release often" paradigm. It will likely take me a few weeks to finish researching this chip, and I didn't want to keep the work I had private during that time. But rest assured, bsnes v034 should feature much faster SPC7110 emulation.
neviksti, Andreas Naive and jolly_codger worked non-stop on the SPC7110 decompression algorithm for the past two weeks. caitsith2 provided valuable data to the effort. I only wish that I could've been of some use, but alas, I had no role in this. In the end, it was neviksti who managed to crack all three(!!) compression modes of this chip, which turned out to be a customized 8-bit QM-coder with a prediction model. You can read more about this here. I would also like to thank Dark Force and John Weidman (aka The Dumper) for their research notes on the SPC7110 register interface.
For those who don't understand the hoopla about figuring out this compression algorithm when we already had graphics pack simulation, I should note that we have since found a few errors in these packs. Not to mention, you no longer need ~4-16MB packs for each game you wish to run. They work like any other game now. Better still, the chip can now be used to compress new graphics, eg for any future translation efforts on these titles.
The real-time clocks in both Far East of Eden Zero and Dai Kaijuu Monogatari 2 will now save a ".rtc" file in your save folder, which contains the clock as set by the video game, as well as a timestamp from your computer when the time was last updated. It uses the difference between the saved timestamp and current time to update the time. This allows you to specify any time you like, whereas previously bsnes would just use your computer's current time, ignoring the time you set in-game. It also allows the "round clock by 30 seconds" option in both games to work. I avoided this before because this method makes supporting daylight savings time and such impractical, although I should note that the original hardware did not support DST, either. This method was required to pass the SPC7110 tests, and is overall much more faithful to how the original chips worked.
Once again, I'd really like to personally thank neviksti for his tireless efforts. Eliminating graphics packs from SNES emulation was one of my primary reasons for getting involved in the SNES emulation scene. That neviksti managed to crack this algorithm means a lot to me. Thank you so much, neviksti. This release is dedicated to you, now go get some sleep ;)
[url]http://byuu.cinnamonpirate.com/[/url] bsnes v0.034 released
For this release: SPC7110 emulation speed has been greatly optimized, massive improvements to HDMA timing have been implemented, Multitap support was added, and the user interface was polished a bit more.
Changelog:
SPC7110 decompression code updated to latest version by neviksti and converted to a state machine; SPC7110 overhead is now identical to S-DD1 overhead (eg ~5% speed hit over standard games)
Fixed a major bug in SPC7110 data port emulation that was crashing Super Power League 4 [Jonas Quinn]
HDMA trigger point corrected to H=1104, bus sync timing corrected
All illegal DMA A-bus accesses should now be properly blocked
DMA state machine rewritten, greatly simplified
Major corrections to HDMA run timing; fixes flickering bugs in Mecarobot Golf and Super Mario Kart
Emulator now defaults to 2/1/3 SNES (CPU/PPU1/PPU2 revision numbers)
Multitap emulation added, can be attached to either or both controller ports; user interface updated to reflect this
Status messages (cartridge loaded / unloaded, UPS patch applied, etc) now appear in status bar
Added advanced configuration option, "input.analog_axis_resistance", to control gamepad analog stick sensitivity
Also, the SPC7110 emulator download link below was removed: if you are looking for this, please download the bsnes v034 source code, which has the most up-to-date version in the src/chip/spc7110 folder.
[url]http://byuu.cinnamonpirate.com/[/url] bsnes v0.035 released
This release adds vsync support, improved header detection and many new configuration options. Many thanks go to I.S.T. for extensively testing the new header detection for regressions.
Changelog:
Added video synchronization support at long last [blargg, byuu]
Added audio panel to control volume, latency, frequency and SNES input frequency settings
Added driver panel to select APIs to use for video, audio and input
Added crash handler for driver initialization
Xv and SDL video drivers now work with compositing enabled on Linux/Xorg

[url]http://byuu.cinnamonpirate.com/[/url] bsnes v0.036 released
This release fixes a somewhat serious bug introduced in v035, and also vastly improves Windows support for non-ANSI filenames.
[url]http://byuu.cinnamonpirate.com/[/url] bsnes v0.037 released
This release adds support for the SNES mouse, Super Scope and Justifier peripherals. It also simplifies cartridge loading and refines the user interface. Lastly, GZ and ZIP archives can now contain non-ANSI characters (Chinese, Japanese, Russian, ...) This support existed in the last release for all uncompressed files. Together, this means only JMA support on Windows lacks support for loading non-ANSI filenames. This is due to the library itself (really, it's more Windows' fault), and licensing issues prevent me from patching libjma as I did with zlib (bsnes is not GPL compatible.) I'm planning to work with Nach to fix this in a future release.
About the cartridge loading changes ... the emulator now determines what kind of cartridge is being loaded (eg normal, BS-X BIOS, Sufami Turbo cart, etc) by looking inside the file itself. If it detects a cart type that requires more than one ROM image to load, it will present you with the appropriate specialized load menu automatically. Aside from being more intuitive, this method also allows loading of BS-X and Sufami Turbo games from the command-line or via file association.
Changelog:
added mouse support to DirectInput and SDL input drivers
up to 96 buttons per controller; 8 buttons per mouse (5 per mouse on Linux) can be mapped now

[url]http://byuu.cinnamonpirate.com/[/url] bsnes v0.044 released
This release adds full SA-1 support, with no known issues. All 26 games have been tested by myself and others, and a few have been beaten from start to finish. The latter include Super Mario RPG, Kirby's Dreamland 3, Kirby Super Star and Jikkyou Oshaberi Parodius.
Please understand that the SA-1 is essentially four times faster than the SNES' main CPU, so system requirements will be very high for these games. For example, on an E8400 @ 3.0GHz, I average ~160fps in ordinary games. But for SA-1 emulation, this drops to ~90fps, with the worst case being ~80fps.
[url]http://byuu.cinnamonpirate.com/[/url] bsnes v0.045 released
This is a maintenance release to fix a crashing bug in S-DD1 games (Star Ocean, Street Fighter Alpha 2), and a video issue in games using the WAI instruction.
As always, my apologies for any inconvenience. SA-1 support required modification of a large amount of delicate code in the emulation core, and our limited testing team was not able to catch these in time before release.

[url]http://byuu.org/[/url] bsnes v0.054
This release is essentially the same as v053, but it's now at least as fast as v052 was, and ~10% faster than v053, which lacked profiling.
I did add in two quick changes, however: first, when starting in fullscreen mode, the video output size was being incorrectly set to the windowed size; second, by requiring save states to match the CRC32 of games, it made debugging with them impossible, so I've turned off the CRC32 matching.

[url]http://byuu.org/[/url] bsnes v0.057
I'm really sorry about this, but a major issue snuck into v056. It was caused by a bug in the newly released Qt 4.6.0 RC1. Whenever one moved the mouse cursor over the main window in the Windows port, the frame rate was immediately cut in half, which effectively ruined Mouse, Super Scope and Justifier support. As for how this could happen, well ... I'm ... really at a loss for words about this.
This release does not change the source code at all except to increment the version number, and it is built against Qt 4.6.0 beta 1 instead of 4.6.0 release candidate 1 as v055 was.
I will file an official bug complaint and post a link to it here during next week. Again, my apologies for any inconvenience. I incorrectly assumed it would be safe to update to RC1, and didn't spot the bug in time.
[url]http://byuu.org/[/url] bsnes v0.058 released
2009-12-09We've tested the latest release on at least a dozen computers now, all seems to be in order for a release.
Changelog:

◦Super Game Boy 2 now runs at the correct hardware speed, and not 2.4% faster like the Super Game Boy 1 does
◦added Vsync support to the Windows OpenGL driver (Intel graphics drivers do not support this option, because their engineers are lazy)
◦OpenGL driver no longer re-initializes when changing video synchronization, helps pixel shaders
◦refactored user interface compilation; now split into several object files, auto-generated MOC files placed under src/obj/

◦added disassembler that can trace both forward and backward from the current execution address
◦extended read/write breakpoints to the S-SMP
◦re-added trace masking option
Errata: there is one known bug in Qt 4.6.0 that affects the Windows port: menus attached to buttons show up as invisible on Windows Vista and above. I only use this on the file load dialog options button, and only to toggle the information pane on and off. Given that this is less severe than the bugs in the beta versions, I've upgraded anyway. I'll submit a bug report to the Qt team for this shortly. Also, my sincerest thanks to Bradley Hughes from the Qt development team for quickly fixing this show-stopper bug that greatly affected performance in bsnes v056.
New pages: I've added a new page to the navigation menu to explain 21fx, and I've also added a bsnes compilation guide on the main bsnes page. Please check those out for more information.

[url]http://byuu.org/[/url] bsnes v061 beta released
Please keep in mind that bsnes v060 remains the current stable release. v061 has been released as a work-in-progress build. As such, it is only available at Google Code.
I am releasing this WIP to allow the public to test out and comment on the new XML mapping system, as well as the integration of mightymo's cheat code database into the cheat editor. I would greatly appreciate feedback on these two on the forums.
There are some important issues with this release. The biggest is the move to C++0x. This requires GCC 4.4.0 or newer to compile, thus it is not currently possible to build this on OS X using Xcode. Nor would it be possible on certain BSDs or older distros. If you have an older compiler, please stick with v060, or use a binary release where available.
Another issue is that TDM/GCC 4.4.1 for Windows crashes with an internal compiler error when attempting to generate a profile for the DSP-1 module. This is a bug in the compiler, and not in the code itself. The workaround is to simply omit profile-guided optimization for this one object.
Lastly, there's also a known bug in the memory mapping. If you load an SA-1 game, SuperFX games will not load properly afterward unless you restart the emulator. I'm looking into the cause now, but it didn't seem serious enough to hold up a WIP release.
So, yes. If you want a good gaming experience that's been fully tested and stable, please stick with v060. If you want to see some bleeding edge features, I'd appreciate feedback on v061. Thanks for reading this.
Changelog:
◦added mightymo's cheat code database, access via "Find Cheat Codes" button on cheat editor window
◦added an option to temporarily disable all cheat codes quickly
◦debugger now properly uses S-SMP IPLROM when needed for disassembling and tracing
◦indexed indirect read opcodes in the S-CPU were testing for IRQs one cycle too early [someone42]
◦fix an off-by-one array iteration in S-PPU OAM rendering [PiCiJi]
◦added some implicit linked libraries to linker flags for Fedora [belegdol]
◦moved from C++98 to C++0x, resulting in substantial code cleanups and simplifications
◦C++0x: implemented foreach() concept for linear container iteration
◦C++0x: implemented concept system using SFINAE and type traits
◦C++0x: utilized auto keyword to increase source readability
◦C++0x: moved to strongly-typed enumerators
◦C++0x: rewrote va_list-based code to use type-safe variadic templates
◦C++0x: replaced noncopyable class with deleted default copy functions
◦C++0x: replaced custom static_assert template class with built-in version
◦C++0x: utilized rvalue references to implement move semantics into string, array, vector and serialization classes
◦C++0x: utilized std::initializer_list for { ... } initialization support to lstring, array and vector classes
[url]http://byuu.org/[/url] bsnes v062 beta released
[url]http://byuu.org/[/url] bsnes v062.04 beta
I suppose I should start calling these nightlies, heh. blargg went ahead and verified every last possible edge case with regards to the S-CPU MUL / DIV registers. It uncovered a few errors in my implementation, which have since been corrected. The design used now should be a direct reflection of the hardware implementation: no actual multiplication, no actual division, and no variable-length bit-shifting.
We also spent about eight hours straight hammering away at the S-SMP test register. We have a partial understanding of TEST.d3 and TEST.d0, and a complete understanding of the other six bits. All of this has been implemented as well.
Lastly, snesreader gets a tiny update to fix Test Drive II, which broke due to a slight regression when porting the mapping code to XML.
[url]http://byuu.org/[/url] bsnes v064 released
A thank you to everyone who helped test the RC to ensure stability. I've uploaded the official v064 release to Google Code.
The most important change in this release is the cycle-based PPU renderer; but due to performance reasons the scanline-based renderer remains the default in the Windows binary. If you want to try out the cycle-based renderer, you will need to compile from source for now.
Another major change is the introduction of libsnes, which allows one to build bsnes as a shared library that can be used from other programming languages. It is intended both to create a regression testing framework, and to provide API stability for the various projects that use the bsnes core. While I can't guarantee the API to libsnes won't change, I will properly revision it and do everything I can to avoid changing it if possible.
[url]http://byuu.org/[/url] bsnes v065 released
It's been a while, so here is a new release of bsnes.
Unfortunately I don't have a full changelog this time. Most of the work went into stabilizing libsnes (which is used by the experimental .NET, Cocoa and Python UIs; as well as by Richard Bannister's OS X port).
The Windows binary package now comes with all three variants included: bsnes.exe, the standard version that casual users should run; bsnes-debugger.exe, for SNES programmers and ROM hackers only; and bsnes-accurate.exe, which should not be used by anybody, ever.
In all seriousness, bsnes-accurate.exe is bsnes with the dot-based S-PPU renderer. It's twice as slow as the normal build, and you won't really notice any differences except in Air Strike Patrol. It's there for the curious and for any SNES programmers who want to try making some really awesome video demos.
Changelog:
◦OS X port builds once again; now requires gcc44 from Macports
◦libsnes API finalized
◦fixed a bug with S-CPU debugger breakpoints
◦various source cleanup
[url]http://byuu.org/[/url] bsnes v066 released2010-07-31
Major features in this release are: serial controller emulation, a brand new scheduler that supports multiple simultaneous coprocessors, and accuracy improvements.
The serial controller is something devised by blargg. With the proper voltage adjustments (5v-9v), it is possible to wire an SNES controller to a serial port, which can then be used for bidirectional communication between the SNES, and (usually, but not only) a PC. The support in bsnes was added so that such programs could be debugged and ran from within an emulator, and not just on real hardware.
The scheduler rewrite was meant to allow the combination of coprocessors. It was specifically meant to allow the serial controller thread to run alongside the SuperFX and SA-1 coprocessor threads, but it also allows fun things like MSU1 support in SuperFX and SA-1 games, and even creating dev cartridges that utilize both the SuperFX and SA-1 at the same time. The one thing not yet allowed is running multiple instances of the exact same coprocessor at the same time, as this is due to design constraints favoring code inlining.
There are two important accuracy updates. The first is that when PAL video mode is used without being in overscan mode, black bars are shown. Emulators have always shown this black bar at the bottom of the screen, but this is actually incorrect. resxto took pictures from his PAL TV that shows the image is in fact vertically centered in the screen. bsnes has been updated to reflect this.
Also interesting is that I have backported some code from the dot-based PPU renderer. In the game Uniracers, it writes to OAM during Hblank, and expects the write to go to a specific address. In previous releases, that address was hard-coded to go to the required memory location. But the way the hardware really works is that the write goes to the extended attribute address for the last sprite that the PPU fetched, as the PPU is still asserting the OAM address bus. Now, due to the precision limitations, I was not able to also port timing access during the active display period. However, this is sufficient to at least remove the last global hack from the older, speed-focused scanline renderer.
[url]http://byuu.org/[/url] bsnes v067 released2010-08-01
I apologize, bsnes v066 had a small error in the source that resulted in the PPU not synchronizing properly to the CPU. This bug was not exposed in the images I use to test releases. I have also updated the cheat code database, which is maintained by mightymo.
