Update to v104r06 release.
byuu says: Changelog: - gba,ws: removed Thread::step() override¹ - processor/m68k: move.b (a7)+ and move.b (a7)- adjust a7 by two, not by one² - tomoko: created new initialize(Video,Audio,Input)Driver() functions³ - ruby/audio: split Audio::information into Audio::available(Devices,Frequencies,Latencies,Channels)³ - ws: added Model::(WonderSwan,WonderSwanColor,SwanCrystal)() functions for consistency with other cores ¹: this should hopefully fix GBA Pokemon Pinball. Thanks to SuperMikeMan for pointing out the underlying cause. ²: this fixes A Ressaha de Ikou, Mega Bomberman, and probably more games. ³: this is the big change: so there was a problem with WASAPI where you might change your device under the audio settings panel. And your new device may not support the frequency that your old device used. This would end up not updating the frequency, and the pitch would be distorted. The old Audio::information() couldn't tell you what frequencies, latencies, or channels were available for all devices simultaneously, so I had to split them up. The new initializeAudioDriver() function validates you have a correct driver, or it defaults to none. Then it validates a correct device name, or it defaults to the first entry in the list. Then it validates a correct frequency, or defaults to the first in the list. Then finally it validates a correct latency, or defaults to the first in the list. In this way ... we have a clear path now with no API changes required to select default devices, frequencies, latencies, channel counts: they need to be the first items in their respective lists. So, what we need to do now is go through and for every audio driver that enumerates devices, we need to make sure the default device gets added to the top of the list. I'm ... not really sure how to do this with most drivers, so this is definitely going to take some time. Also, when you change a device, initializeAudioDriver() is called again, so if it's a bad device, it will disable the audio driver instead of continuing to send samples at it and hoping that the driver blocked those API calls when it failed to initialize properly. Now then ... since it was a decently-sized API change, it's possible I've broken compilation of the Linux drivers, so please report any compilation errors so that I can fix them. |

Update to v103r16 release.
byuu says: Changelog: - emulator/audio: added the ability to change the output frequency at run-time without emulator reset - tomoko: display video synchronize option again¹ - tomoko: Settings→Configuration expanded to Settings→{Video, Audio, Input, Hotkey, Advanced} Settings² - tomoko: fix default population of audio settings tab - ruby: Audio::frequency is a double now (to match both Emulator::Audio and ASIO)³ - tomoko: changing the audio device will repopulate the frequency and latency lists - tomoko: changing the audio frequency can now be done in real-time - ruby/audio/asio: added missing device() information, so devices can be changed now - ruby/audio/openal: ported to new API; added device selection support - ruby/audio/wasapi: ported to new API, but did not test yet (it's assuredly still broken)⁴ ¹: I'm uneasy about this ... but, I guess if people want to disable audio and just have smooth scrolling video ... so be it. With Screwtape's documentation, hopefully that'll help people understand that video synchronization always breaks audio synchronization. I may change this to a child menu that lets you pick between {no synchronization, video synchronization, audio synchronization} as a radio selection. ²: given how much more useful the video and audio tabs are now, I felt that four extra menu items were worth saving a click and going right to the tab you want. This also matches the behavior of the Tools menu displaying all tool options and taking you directly to each tab. This is kind of a hard change to get used to ... but I think it's for the better. ³: kind of stupid because I've never seen a hardware sound card where floor(frequency) != frequency, but whatever. Yay consistency. ⁴: I'm going to move it to be event-driven, and try to support 24-bit sample formats if possible. Who knows which cards that'll fix and which cards that'll break. I may end up making multiple WASAPI drivers so people can find one that actually works for them. We'll see. |

Update to v103r15 release.
byuu says: Changelog: - ruby: rewrote the API interfaces for Video, Audio, Input - ruby/audio: can now select the number of output channels (not useful to higan, sorry) - ruby/asio: various improvements - tomoko: audio settings panel can now select separate audio devices (for ASIO, OSS so far) - tomoko: audio settings panel frequency and latency lists are dynamically populated now Note: due to the ruby API rewrite, most drivers will not compile. Right now, the following work: - video: Direct3D, XShm - audio: ASIO, OSS - input: Windows, SDL, Xlib It takes a really long time to rewrite these (six hours to do the above), so it's going to be a while before we're back at 100% functionality again. Errata: - ASIO needs device(), setDevice() - need to call setDevice() at program startup to populate frequency/latency settings properly - changing the device and/or frequency needs to update the emulator resampler rates The really hard part is going to be the last one: the only way to change the emulator frequency is to flush all the audio streams and then recompute all the coefficients for the resamplers. If this is called during emulation, all audio streams will be erased and thus no sound will be output. I'll most likely be forced to simply ignore device/frequency changes until the user loads another game. It is at least possible to toggle the latency dynamically. |

Update to v103r13 release.
byuu says: Changelog: - gb/interface: fix Game Boy Color extension to be "gbc" and not "gb" [hex\_usr] - ms/interface: move Master System hardware controls below controller ports - sfc/ppu: improve latching behavior of BGnHOFS registers (not hardware verified) [AWJ] - tomoko/input: rework port/device mapping to support non-sequential ports and devices¹ - todo: should add move() to inputDevice.mappings.append and inputPort.devices.append - note: there's a weird GCC 4.9 bug with brace initialization of InputEmulator; have to assign each field separately - tomoko: all windows sans the main presentation window can be dismissed with the escape key - icarus: the single file selection dialog ("Load ROM Image...") can be dismissed with the escape key - tomoko: do not pause emulation when FocusLoss/Pause is set during exclusive fullscreen mode - hiro/(windows,gtk,qt): implemented Window::setDismissable() function (missing from cocoa port, sorry) - nall/string: fixed printing of largest possible negative numbers (eg `INT_MIN`) [Sintendo] - only took eight months! :D ¹: When I tried to move the Master System hardware port below the controller ports, I ran into a world of pain. The input settings list expects every item in the `InputEmulator<InputPort<InputDevice<InputMapping>>>>` arrays to be populated with valid results. But these would be sparsely populated based on the port and device IDs from inside higan. And that is done so that the Interface::inputPoll can have O(1) lookup of ports and devices. This worked because all the port and device IDs were sequential (they left no gaps in the maps upon creating the lists.) Unfortunately by changing the expectation of port ID to how it appears in the list, inputs would not poll correctly. By leaving them alone and just moving Hardware to the third position, the Game Gear would be missing port IDs of 0 and 1 (the controller ports of the Master System). Even by trying to make separate MasterSystemHardware and GameGearHardware ports, things still fractured when the devices were no longer contigious. I got pretty sick of this and just decided to give up on O(1) port/device lookup, and moved to O(n) lookup. It only knocked the framerate down by maybe one frame per second, enough to be in the margin of error. Inputs aren't polled *that* often for loops that usually terminate after 1-2 cycles to be too detrimental to performance. So the new input system now allows non-sequential port and device IDs. Remember that I killed input IDs a while back. There's never any reason for those to need IDs ... it was easier to just order the inputs in the order you want to see them in the user interface. So the input lookup is still O(1). Only now, everything's safer and I return a maybe<InputMapping&>, and won't crash out the program trying to use a mapping that isn't found for some reason. Errata: the escape key isn't working on the browser/message dialogs on Windows, because of course nothing can ever just be easy and work for me. If anyone else wouldn't mind looking into that, I'd greatly appreciate it. Having the `WM_KEYDOWN` test inside the main `Application_sharedProc`, it seems to not respond to the escape key on modal dialogs. If I put the `WM_KEYDOWN` test in the main window proc, then it doesn't seem to get called for `VK_ESCAPE` at all, and doesn't get called period for modal windows. So I'm at a loss and it's past 4AM here >_> |

Update to v103r12 release.
byuu says: Changelog: - ruby/video: cleaned up Direct3D9 driver and fixed catastrophic memory leak - ruby/video: added fullscreen exclusive mode support to the Direct3D9 driver¹ - ruby/video: minor cosmetic code cleanups to various drivers - tomoko: added support to always allow input when in fullscreen exclusive mode - tomoko: fixed window to not remove resizability flag when exiting fullscreen mode ¹: I am assuming that exclusive mode will try to capture the primary monitor. I don't know what will happen in multi-monitor setups, however, as I don't use such a setup here. Also, I am using `D3DPRESENT_DISCARD` instead of `D3DPRESENT_FLIP`. I'm not sure if this will prove better or worse, but I've heard it will waste less memory, and having a BackBufferCount of 1 should still result in page flipping anyway. The difference is supposedly just that you can't rely on the back buffer being a valid copy of the previous frame like you can with FLIP. Lastly, if you want Vsync, you can edit the configuration file to enable that, and then turn off audio sync. Errata: "pause emulation when focus is lost" is not working with exclusive mode. I need to add a check to never auto-pause when in exclusive mode. Thanks to bun for catching that one. |

Update to v102r22 release.
byuu says: Changelog: - higan: Emulator::Interface::videoSize() renamed to videoResolution() - higan: Emulator::Interface::rtcsync() renamed to rtcSynchronize() - higan: added video display rotation support to Video - GBA: substantially improved audio mixing - fixed bug with FIFO 50%/100% volume setting - now properly using SOUNDBIAS amplitude to control output frequencies - reduced quantization noise - corrected relative volumes between PSG and FIFO channels - both PSG and FIFO values cached based on amplitude; resulting in cleaner PCM samples - treating PSG volume=3 as 200% volume instead of 0% volume now (unverified: to match mGBA) - GBA: properly initialize ALL CPU state; including the vital prefetch.wait=1 (fixes Classic NES series games) - GBA: added video rotation with automatic key translation support - PCE: reduced output resolution scalar from 285x242 to 285x240 - the extra two scanlines won't be visible on most TVs; and they make all other cores look worse - this is because all other cores output at 240p or less; so they were all receiving black bars in windowed mode - tomoko: added "Rotate Display" hotkey setting - tomoko: changed hotkey multi-key logic to OR instead of AND - left support for flipping it back inside the core; for those so inclined; by uncommenting one line in input.hpp - tomoko: when choosing Settings→Configuration, it will automatically select the currently loaded system - for instance, if you're playing a Game Gear game, it'll take you to the Game Gear input settings - if no games are loaded, it will take you to the hotkeys panel instead - WS(C): merged "Hardware-Vertical", "Hardware-Horizontal" controls into combined "Hardware" - WS(C): converted rotation support from being inside the core to using Emulator::Video - this lets WS(C) video content scale larger now that it's not bounded by a 224x224 square box - WS(C): added automatic key rotation support - WS(C): removed emulator "Rotate" key (use the general hotkey instead; I recommend F8 for this) - nall: added serializer support for nall::Boolean (boolean) types - although I will probably prefer the usage of uint1 in most cases |

Update to v101r32 release.
byuu says: Changelog: - SMS: fixed controller connection bug - SMS: fixed Z80 reset bug - PCE: emulated HuC6280 MMU - PCE: emulated HuC6280 RAM - PCE: emulated HuCard ROM reading - PCE: implemented 178 instructions - tomoko: removed "soft reset" functionality - tomoko: moved "power cycle" to just above "unload" option I'm not sure of the exact number of HuC6280 instructions, but it's less than 260. Many of the ones I skipped are HuC6280-originals that I don't know how to emulate just yet. I'm also really unsure about the zero page stuff. I believe we should be adding 0x2000 to the addresses to hit page 1, which is supposed to be mapped to the zero page (RAM). But when I look at turboEMU's source, I have no clue how the hell it could possibly be doing that. It looks to be reading from page 0, which is almost always ROM, which would be ... really weird. I also don't know if I've emulated the T mode opcodes correctly or not. The documentation on them is really confusing. |

Update to v098r13 release.
byuu says: Changelog: - nall/dsp returns with new iir/biquad.hpp and resampler/cubic.hpp files - nall/queue.hpp added (simple ring buffer ... nall/vector wouldn't cause too many moves with FIFO) - audio streams now only buffer 20ms; so even if multiple audio streams desync, latency can never exceed 20ms - replaced blackman windwed sinc FIR hermite audio filter with transposed direct form II biquadratic sixth-order IIR butterworth filter (better attenuation of frequencies above 20KHz, faster, no need for decimation, less code) - put in experimental eight-tap echo filter (a lot better than what I had before, but still rather weak) - substantial cleanups to the SuperFX GSU processor core (slightly faster, 479KB->100KB object file, 42.7KB->33.4KB source code size, way less code duplication) We'll definitely want to test the whole SuperFX library (not many games) just to make sure there's no regressions caused by this one. Not sure what I want to do with audio processing effects yet. I've always really wanted lots of fun controls to customize audio, and now finally with this new biquad filter, I can finally start implementing real effects. For instance, an equalizer wouldn't be too complicated anymore. The new reverb effect is still a poor man's version. I need to find human readable source for implementing a comb-filter properly. I'm pretty sure I can already treat nall::queue as an all-pass filter since all that does is phase shift (fancy audio term for "delay audio"). What's really going to be hard is figuring out how to expose user-friendly settings for controlling it. It looks like you need a bunch of coprime coefficients, and I don't think casual users are going to be able to hand-enter coprime values to get the echo effect they want. I uh ... don't even know how to calculate coprime values dynamically right now >_> But we're going to have to, as they are correlated to the output sampling rate. We'll definitely want to make some audio profiles so that users can quickly select pre-configured themes that sound nice, but expose the underlying coefficients so that they can tweak stuff to their liking. This isn't just about higan, this is about me trying to learn digital signal processing, so please don't be too upset about feature creep or anything on this. Anyway ... I'm having some difficulties with my audio right now. When the reverb effect is enabled, there's a bunch of static on system reset for just a moment. But this should not be possible. nall::queue is initializing all previous reverb sample elements to 0.0. I don't understand where static is coming in from. Further, we have the same issue with both the windowed sinc and the biquad filters ... a bit of a popping sound when starting a game. Any help tracking this down would be appreciated. There's also one really annoying issue ... I can't seem to do reverb or volume adjustments with normalized samples. If I say "volume *= 0.5" in higan/audio/audio.cpp line 68, it doesn't just halve the volume, it adds a whole bunch of distortion. This makes absolutely zero sense to me. The sample values are between 0.0 (mute) and 1.0 (full volume) here, so multiplying a double by 0.5 shouldn't cause distortion. So right now, I'm doing these adjustments with less precision after denormalizing back to int16. Anyone ever see something like that? :/ |

Update to v098r11 release.
byuu says: Changelog: - fixed nall/path.hpp compilation issue - fixed ruby/audio/xaudio header declaration compilation issue (again) - cleaned up xaudio2.hpp file to match my coding syntax (12.5% of the file was whitespace overkill) - added null terminator entry to nall/windows/utf8.hpp argc[] array - nall/windows/guid.hpp uses the Windows API for generating the GUID - this should stop all the bug reports where two nall users were generating GUIDs at the exact same second - fixed hiro/cocoa compilation issue with uint# types - fixed major higan/sfc Super Game Boy audio latency issue - fixed higan/sfc CPU core bug with pei, [dp], [dp]+y instructions - major cleanups to higan/processor/r65816 core - merged emulation/native-mode opcodes - use camel-case naming on memory.hpp functions - simplify address masking code for memory.hpp functions - simplify a few opcodes themselves (avoid redundant copies, etc) - rename regs.* to r.* to match modern convention of other CPU cores - removed device.order<> concept from Emulator::Interface - cores will now do the translation to make the job of the UI easier - fixed plurality naming of arrays in Emulator::Interface - example: emulator.ports[p].devices[d].inputs[i] - example: vector<Medium> media - probably more surprises Major show-stoppers to the next official release: - we need to work on GB core improvements: LY=153/0 case, multiple STAT IRQs case, GBC audio output regs, etc. - we need to re-add software cursors for light guns (Super Scope, Justifier) - after the above, we need to fix the turbo button for the Super Scope I really have no idea how I want to implement the light guns. Ideally, we'd want it in higan/video, so we can support the NES Zapper with the same code. But this isn't going to be easy, because only the SNES knows when its output is interlaced, and its resolutions can vary as {256,512}x{224,240,448,480} which requires pixel doubling that was hard-coded to the SNES-specific behavior, but isn't appropriate to be exposed in higan/video. |

Update to v098r06 release.
byuu says: Changelog: - emulation cores now refresh video from host thread instead of cothreads (fix AMD crash) - SFC: fixed another bug with leap year months in SharpRTC emulation - SFC: cleaned up camelCase on function names for armdsp,epsonrtc,hitachidsp,mcc,nss,sharprtc classes - GB: added MBC1M emulation (requires manually setting mapper=MBC1M in manifest.bml for now, sorry) - audio: implemented Emulator::Audio mixer and effects processor - audio: implemented Emulator::Stream interface - it is now possible to have more than two audio streams: eg SNES + SGB + MSU1 + Voicer-Kun (eventually) - audio: added reverb delay + reverb level settings; exposed balance configuration in UI - video: reworked palette generation to re-enable saturation, gamma, luminance adjustments - higan/emulator.cpp is gone since there was nothing left in it I know you guys are going to say the color adjust/balance/reverb stuff is pointless. And indeed it mostly is. But I like the idea of allowing some fun special effects and configurability that isn't system-wide. Note: there seems to be some kind of added audio lag in the SGB emulation now, and I don't really understand why. The code should be effectively identical to what I had before. The only main thing is that I'm sampling things to 48000hz instead of 32040hz before mixing. There's no point where I'm intentionally introducing added latency though. I'm kind of stumped, so if anyone wouldn't mind taking a look at it, it'd be much appreciated :/ I don't have an MSU1 test ROM, but the latency issue may affect MSU1 as well, and that would be very bad. |

Update to v098r05 release.
byuu says: Changelog: - WS/WSC: re-added support for screen rotation (code is inside WS core) - ruby: changed sample(uint16_t left, uint16_t right) to sample(int16_t left, int16_t right); - requires casting to uint prior to shifting in each driver, but I felt it was misleading to use uint16_t just to avoid that - ruby: WASAPI is now built in by default; has wareya's improvements, and now supports latency adjust - tomoko: audio settings panel has new "Exclusive Mode" checkbox for WASAPI driver only - note: although the setting *does* take effect in real-time, I'd suggest restarting the emulator after changing it - tomoko: audio latency can now be set to 0ms (which in reality means "the minimum supported by the driver") - all: increased cothread size from 512KiB to 2MiB to see if it fixes bullshit AMD driver crashes - this appears to cause a slight speed penalty due to cache locality going down between threads, though |

byuu says: Changelog: - SFC: balanced profile removed - SFC: performance profile removed - SFC: code for handling non-threaded CPU, SMP, DSP, PPU removed - SFC: Coprocessor, Controller (and expansion port) shared Thread code merged to SFC::Cothread - Cothread here just means "Thread with CPU affinity" (couldn't think of a better name, sorry) - SFC: CPU now has vector<Thread*> coprocessors, peripherals; - this is the beginning of work to allow expansion port devices to be dynamically changed at run-time - ruby: all audio drivers default to 48000hz instead of 22050hz now if no frequency is assigned - note: the WASAPI driver can default to whatever the native frequency is; doesn't have to be 48000hz - tomoko: removed the ability to change the frequency from the UI (but it will display the frequency used) - tomoko: removed the timing settings panel - the goal is to work toward smooth video via adaptive sync - the model is broken by not being in control of the audio frequency anyway - it's further broken by PAL running at 50hz and WSC running at 75hz - it was always broken anyway by SNES interlace timing varying from progressive timing - higan: audio/ stub created (for now, it's just nall/dsp/ moved here and included as a header) - higan: video/ stub created - higan/GNUmakefile: now includes build rules for essential components (libco, emulator, audio, video) The audio changes are in preparation to merge wareya's awesome WASAPI work without the need for the nall/dsp resampler. |

Update to v097r12 release.
byuu says: Nothing WS-related this time. First, I fixed expansion port device mapping. On first load, it was mapping the expansion port device too late, so it ended up not taking effect. I had to spin out the logic for that into Program::connectDevices(). This was proving to be quite annoying while testing eBoot (SNES-Hook simulation.) Second, I fixed the audio->set(Frequency, Latency) functions to take (uint) parameters from the configuration file, so the weird behavior around changing settings in the audio panel should hopefully be gone now. Third, I rewrote the interface->load,unload functions to call into the (Emulator)::System::load,unload functions. And I have those call out to Cartridge::load,unload. Before, this was inverted, and Cartridge::load() was invoking System::load(), which I felt was kind of backward. The Super Game Boy really didn't like this change, however. And it took me a few hours to power through it. Before, I had the Game Boy core dummying out all the interface->(load,save)Request calls, and having the SNES core make them for it. This is because the folder paths and IDs will be different between the two cores. I've redesigned things so that ICD2's Emulator::Interface overloads loadRequest and saveRequest, and translates the requests into new requests for the SuperFamicom core. This allows the Game Boy code to do its own loading for everything without a bunch of Super Game Boy special casing, and without any awkwardness around powering on with no cartridge inserted. This also lets the SNES side of things simply call into higher-level GameBoy::interface->load,save(id, stream) functions instead of stabbing at the raw underlying state inside of various Game Boy core emulation classes. So things are a lot better abstracted now. |

Update to v096r07 release.
byuu says: Changelog: - configuration files are now stored in localpath() instead of configpath() - Video gamma/saturation/luminance sliders are gone now, sorry - added Video Filter->Blur Emulation [1] - added Video Filter->Scanline Emulation [2] - improvements to GBA audio emulation (fixes Minish Cap) [Jonas Quinn] [1] For the Famicom, this does nothing. For the Super Famicom, this performs horizontal blending for proper pseudo-hires translucency. For the Game Boy, Game Boy Color, and Game Boy Advance, this performs interframe blending (each frame is the average of the current and previous frame), which is important for things like the GBVideoPlayer. [2] Right now, this only applies to the Super Famicom, but it'll come to the Famicom in the future. For the Super Famicom, this option doesn't just add scanlines, it simulates the phosphor decay that's visible in interlace mode. If you observe an interlaced game like RPM Racing on a real SNES, you'll notice that even on perfectly still screens, the image appears to shake. This option emulates that effect. Note 1: the buffering right now is a little sub-optimal, so there will be a slight speed hit with this new support. Since the core is now generating native ARGB8888 colors, it might as well call out to the interface to lock/unlock/refresh the video, that way it can render directly to the screen. Although ... that might not be such a hot idea, since the GBx interframe blending reads from the target buffer, and that tends to be a catastrophic option for performance. Note 2: the balanced and performance profiles for the SNES are completely busted again. This WIP took 6 1/2 hours, and I'm exhausted. Very much not looking forward to working on those, since those two have all kinds of fucked up speedup tricks for non-interlaced and/or non-hires video modes. Note 3: if you're on Windows and you saved your system folders somewhere else, now'd be a good time to move them to %localappdata%/higan |
