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.

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.

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.

◦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/
◦worked around a bug in the PulseAudio sound server that was causing the ALSA output driver to lock up [BearOso]
◦rewrote and simplified the save state manager, it is no longer a part of the core

◦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.

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

bsnes v062 beta released

天下布武

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.

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.

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

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.

bsnes v076 released 2011-02-25

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:
◦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
