Higan/BSNES (Cycle accurate SNES emulator) seems to be back in active development

Higan v095 is now out.

"Just when I thought I was out ... they pull me back in!"

After 20 months of development, higan v095 is released at long last!

The most notable feature is vastly improved Game Boy Advance emulation. With many thanks to endrift, Cydrak, Jonas Quinn and jchadwick, this release contains substantially improved CPU timings and many bugfixes. Being one of only two GBA emulators to offer ROM prefetch emulation, higan is very near mGBA in terms of accuracy, and far ahead of all others. As a result of these fixes, compatibility is also much higher than in v094.

There are also several improvements to SNES emulation. Most significantly is support for mid-scanline changes to the background mode in the accuracy profile.

Due to substantial changes to the user interface library used by higan, this release features yet again a brand-new UI. With the exception of video shaders and NSS DIP switch selection, it is at feature-parity with the previous UI. It also offers some new features that v094 lacked.

The cheat code database has also been updated to the latest version by mightymo.

Lastly, I will not be offering official 32-bit Windows binaries going forward. higan will technically build and run on 32-bit systems, but I am tired of having to jump through flaming hoops to update MinGW32's headers that haven't been updated since 1996. The 10% performance hit for running in 32-bit mode is also a significant deterrent. If anyone wants to take over 32-bit Windows builds, I'll happily link them from the higan downloads page.

Note: I'm working on a new user guide to explain how to use higan and icarus. So if you have trouble using this release, check back here in a few days please. But essentially, you run icarus to import your games, and then higan to play them. It's a bit different from the direct integration of ananke with v094.

So Higan and another emulator are the best in terms of cycle accurate GBA emulation?

Apparently. mGBA surpassed VBA-M as the top GBA emulator a little while ago and it sounds like byuu was able to incorporate a lot of mGBA's fixes to greatly improve Higan's GBA core.
 
> So, byuu's back or he never actually left?

I stopped for about a year, spent a while where I only accepted third-party patches in a kind of maintenance mode (was trying to pursue some other goals in life, and of course failed), and eventually picked things back up to get a new release out. That last part took me from around April until today to complete >_<

For the future, I'd like to work on the SNES debugger again, and then I'd like to improve my NES mapper emulation.

> Apparently. mGBA surpassed VBA-M as the top GBA emulator a little while ago and it sounds like byuu was able to incorporate a lot of mGBA's fixes to greatly improve Higan's GBA core.

Yeah, mGBA is now the best GBA emulator. endrift wrote a bunch of tests so we could finally emulate prefetch instead of just guessing how it worked. His emulator passes around 1060/1280 tests, and mine 1010/1280. All the other emulators are at 500/1280 or less. higan v094 was only at around 180/1280, so this is a huge jump for me.

Of course, that's just timing. There's a lot more to GBA emulation. Where mGBA really shines is that it also implements the solar sensor, the RTC, the link cable, and has some strides toward working with Dolphin's Game Boy Player emulation.

The main "cool feature" I have is native GBP simulation, so the rumble feature works as if you were playing on the GBP with a GC controller. Also have a really nice new GBA color simulation from Cydrak that's way better than any others. But the only serious reasons to use mine instead of mGBA, is if you like the game folder idea (people either love it or hate it), and/or like the idea of having all the 2D NES systems emulated by the same program.
 
I didn't hear about mGBA before. I think I'm gonna give it a try. And it's great news that higan is still in development.
 
Higan v096 is now out.

This release adds many UI refinements, new features, and GBA emulation improvements.

I'm looking for Super Famicom console donations, so that I can include hardware PCB scans and document differences for my SNES preservation efforts. If anyone would be interested in helping, I'd be very grateful. More about this here.

Also, I've attempted to add a WASAPI audio driver for the Windows port, but I'm having trouble getting it stable. If there are any WASAPI experts that could lend a hand there, that would also be very helpful!

Higan v097 is now out.

This release features improvements to all emulation cores, but most substantially for the Game Boy core. All of blargg's test ROMs that pass in gambatte now either pass in higan, or are off by 1-2 clocks (the actual behaviors are fully emulated.) I consider the Game Boy core to now be fairly accurate, but there's still more improvements to be had.

Also, what's sure to be a major feature for some: higan now has full support for loading and playing ordinary ROM files, whether they have copier headers, weird extensions, or are inside compressed archives. You can load these games from the command-line, from the main Library menu (via Load ROM Image), or via drag-and-drop on the main higan window. Of course, fans of game folders and the library need not worry: that's still there as well.

Also new, you can drop the (uncompressed) Game Boy Advance BIOS onto the higan main window to install it into the correct location with the correct file name.

Lastly, this release technically restores Mac OS X support. However, it's still not very stable, so I have decided against releasing binaries at this time. I'd rather not rush this and leave a bad first impression for OS X users.

Changelog:

- higan: project source code hierarchy restructured; icarus directly integrated
- higan: added software emulation of color-bleed, LCD-refresh, scanlines, interlacing
- icarus: you can now load and import ROM files/archives from the main higan menu
- NES: fixed manifest parsing for board mirroring and VRC pinouts
- SNES: fixed manifest for Star Ocean
- SNES: fixed manifest for Rockman X2,X3
- GB: enabling LCD restarts frame
- GB: emulated extra OAM STAT IRQ quirk required for GBVideoPlayer (Shonumi)
- GB: VBK, BGPI, OBPI are readable
- GB: OAM DMA happens inside PPU core instead of CPU core

- GB: improved timings of several CPU opcodes (gekkio)
- GB: improved timings of OAM DMA refresh (gekkio)
- GB: CPU uses open collector logic; return 0xFF for unmapped memory (gekkio)
- GBA: fixed sequencer enable flags; fixes audio in Zelda - Minish Cap (Jonas Quinn)
- GBA: fixed disassembler masking error (Lioncash)
- hiro: Cocoa support added; higan can now be compiled on Mac OS X 10.7+
- nall: improved program path detection on Windows
- higan/Windows: moved configuration data from %appdata% to %localappdata%
- higan/Linux,BSD: moved configuration data from ~/.config/higan to ~/.local/higan

Does anyone want to be awesome and compile the Mac version for me?

Pretty please? :3

Edit: I actually think I got it, although it's not loading games. Can't figure out if that's because OS X support is unfinished, or I did something wrong.
 
Higan v098 is now out.

This release adds WonderSwan, WonderSwan Color and SwanCrystal emulation. Note that the SwanCrystal is 99.9% identical to the WonderSwan Color sans the LCD panel type; thus going forward I won't be including it in the list of emulated systems.

Please note that this will be the final higan release to include the balanced and performance cores. The accuracy core has now become the only core used by higan.

Furthermore, to simplify naming, the internal emulation cores are now nameless. This means bnes, bsnes, bgb, bgba and bws are now all just part of higan. loki is thus both a subset (the SNES core alone) and superset (with added debugging capabilities) of higan. The internal names were meaningless anyway, as they were never exposed anywhere except one line in each core's source code.

Well this thing crashes every time I load anything. I remember having other usability issues the last time I tried this emulator.

Honestly I don't see any real reason to use higan itself specifically these days; all of his emulation engines are ported to Retroarch, where you can get all the benefits of the super-accurate emulation in a more standardized container.
 
Higan v099 is now out.

Time for a new release. There are a few important emulation improvements and a few new features; but for the most part, this release focuses on major code refactoring, the details of which I will mostly spare you.

The major change is that, as of v099, the SNES balanced and performance cores have been removed from higan. Basically, in addition to my five other emulation cores, these were too much of a burden to maintain. And they've come along as far as I was able to develop them. If you need to use these cores, please use these two from the v098 release.

I'm very well aware that ~80% of the people using higan for SNES emulation were using the two removed profiles. But they simply had to go. Hopefully in the future, we can compensate for their loss by increasing the performance of the accuracy core.

If you want to know more about the removal of these two profiles, please read this article for a more in-depth explanation.

Changelog:

- SFC: balanced profile removed
- SFC: performance profile removed
- SFC: expansion port devices can now be changed during gameplay (atlhough you shouldn't)
- SFC: fixed bug in SharpRTC leap year calculations
- SFC: emulated new research findings for the S-DD1 coprocessor
- SFC: fixed CPU emulation-mode wrapping bug with pei, [dp], [dp]+y instructions [AWJ]
- SFC: fixed Super Game Boy bug that caused the bottom tile-row to flicker in games
- GB: added MBC1M (multi-cart) mapper; icarus can't detect these so manual manifests are needed for now
- GB: corrected return value when HuC3 unmapped RAM is read; fixes Robopon [endrift]
- GB: improved STAT IRQ emulation; fixes Altered Space, etc [endrift, gekkio]
- GB: partial emulation of DMG STAT write IRQ bug; fixes Legend of Zerd, Road Rash, etc
- nall: execute() fix, for some Linux platforms that had trouble detecting icarus
- nall: new BitField class; which allows for simplifying flag/register emulation in various cores
- ruby: added Windows WASAPI audio driver (experimental)
- ruby: remove attempts to call glSwapIntervalEXT (fixes crashing on some Linux systems)
- ui: timing settings panel removed
- video: restored saturation, gamma, luminance settings
- video: added new post-emulation sprite system; light gun cursors are now higher-resolution
- audio: new resampler (6th-order Butterworth biquad IIR); quite a bit faster than the old one
- audio: added optional basic reverb filter (for fun)
- higan: refresh video outside cooperative threads (workaround for shoddy code in AMD graphics drivers)
- higan: individual emulation cores no longer have unique names
- higan: really substantial code refactoring; 43% reduction in binary size

Higan v100 is now out.

higan has finally reached v100!

I feel it's important to stress right away that this is not "version 1.00", nor is it a major milestone release. Rather than arbitrary version numbers, all of my software simply bumps version numbers by one for each official release. As such, higan v100 is simply higan's 100th release.

That said, the primary focus of this release has been code clean-ups. These are always somewhat dangerous in that regressions are possible. We've tested through sixteen WIP revisions, one of which was open to the public, to try and minimize any regressions. But all the same, please report any regressions if you discover any.

Changelog:

FC: render during pixels 1-256 instead of 0-255 [hex_usr]
FC: rewrote controller emulation code
SFC: 8% speedup over the previous release thanks to PPU optimizations
SFC: fixed nasty DB address wrapping regression from v099
SFC: USART developer controller removed; superseded by 21fx
SFC: Super Multitap option removed from controller port 1; ports renamed 2-5
SFC: hidden option to experiment with 128KB VRAM (strictly for novelty)
higan: audio volume no longer divided by number of audio streams
higan: updated controller polling code to fix possible future mapping issues
higan: replaced nall/stream with nall/vfs for file-loading subsystem
tomoko: can now load multi-slotted games via command-line
tomoko: synchronize video removed from UI; still available in the settings file
tomoko, icarus: can navigate to root drive selection on Windows
all: major code cleanups and refactoring (~1MB diff against v099)

Note 1: the audio volume change means that SGB and MSU1 games won't lose half the volume on the SNES sounds anymore. However, if one goes overboard and drives the sound all the way to max volume with the MSU1, clamping may occur. The obvious solution is not to drive volume that high (it will vastly overpower the SNES audio, which usually never exceeds 25% volume.) Another option is to lower the volume in the audio settings panel to 50%. In general, neither is likely to ever be necessary.

Note 2: the synchronize video option was hidden from the UI because it is no longer useful. With the advent of compositors, the loss of the complicated timing settings panel, support for the WonderSwan and its 75hz display, the need to emulate variable refresh rate behaviors in the Game Boy, the unfortunate latency spike and audio distortion caused by long Vsync pauses, and the arrival of adaptive sync technology ... it no longer makes sense to present this option. However, as stated, you can edit settings.bml to enable this option anyway if you insist and understand the aforementioned risks.

Two new updates!

1. Higan has a logo

2. A new article about emulator latency
 
Higan v101 is now out.

Not a large changelog this time, sorry. This release is mostly to fix the SA-1 issue, and to get some real-world testing of the new scheduler model. Most of the work in the past month has gone into writing a 68000 CPU core; yet it's still only about half-way finished.

Changelog:

- fixed SNES SA-1 IRQ regression (fixes Super Mario RPG level-up screen)
- new scheduler for all emulator cores (precision of 2^-127)
- icarus database adds nine new SNES games
- added Input/Frequency to settings file (allows simulation of latency)

Also, I've added a new tutorial page for higan, concerning firmware and its usage. This is made needlessly difficult right now due to the distribution methods used today. I implore the No-Intro team to please reconsider their position on firmware for the sake of making preservation more complete, and accurate SNES emulation easier for everyone.

Higan v102 is now out.

This release adds very preliminary emulation of the Sega Master System (Mark III), Sega Game Gear, Sega Mega Drive (Genesis), and NEC PC Engine (Turbografx-16). These cores do not yet offer sound emulation, save states or cheat codes.

I'm always very hesitant to release a new emulation core in its alpha stages, as in the past this has resulted in lasting bad impressions of cores that have since improved greatly. For instance, the Game Boy Advance emulation offered today is easily the second most accurate around, yet it is still widely judged by its much older alpha implementation.

However, it's always been tradition with higan to not hold onto code in secret. Rather than delay future releases for another year or two, I'll put my faith in you all to understand that the emulation of these systems will improve over time.

I hope that by releasing things as they are now, I might be able to receive some much needed assistance in improving these cores, as the documentation for these new systems is very much less than ideal.

Also, please note that starting with this release, I am omitting the settings.bml file. This means that you will have to manually configure your gamepad input assignments, and select the appropriate devices from the system menu after loading games. You may also want to select a more conservative driver profile than the default (OpenGL, WASAPI.) If they cause you any troubles, a safer bet would be (Direct3D, DirectSound.)

The good news in omitting this file is that you'll only have to configure inputs once, and you won't lose any customizations by upgrading to future releases.

Higan v103 is now out.

With this release, PC Engine, Master System, Game Gear, Mega Drive and the newly added SuperGrafx support are now quite usable! They're far from the best emulators for these systems, but with many bugfixes, full sound emulation, and save state support ... many games are now fully playable with decent accuracy.

The Game Boy Advance emulation is also now substantially improved with vastly improved sound quality and a new dot-based PPU renderer. With that change, every single component in higan is now cycle-based. Regrettably, these changes do carry a ~20% performance penalty compared to GBA emulation in v102.

Changelog:


  • added SuperGrafx emulation
  • improved audio band-pass filtering for all emulated systems
  • screen rotation is now a hotkey; automatically rotates control bindings
  • screen rotation now supported on the Game Boy Advance as well (used by a small number of games)
  • massive improvements to Mega Drive emulation
  • massive code cleanups and rewrites to many CPU emulation cores (MOS6502, WDC65816, SPC700, etc)
  • Famicom, Master System, Mega Drive: added PAL emulation support
  • PC Engine, SuperGrafx, Master System, Game Gear, Mega Drive: added save state support

  • Super Famicom: use darker luma for INIDISP=0 (large improvement to Final Fantasy III opening)
  • Super Famicom: fixed bugs in SMP OR1,AND1 instructions
  • cheat code database regrettably removed from official releases; will be made available separately
This changelog is a summary of major changes. For a detailed list of all changes, which spans several pages, please see the higan Gitlab repository.

Higan v104 is now out.

There are lots of improvements in this new release, both to core emulation and to the user interface. However, some of these changes are quite substantial, so regressions are a possibility. Please report any regressions from v103 on the forums if found.

Note that Mega Drive save RAM files will not be compatible with v103, but will now be compatible with save RAM files from all other Mega Drive emulators, and the format will be stable going forward.

Also!! Thanks to the tireless work of Screwtape, the Help->Documentation link in higan now takes you to a very comprehensive user guide. Please be sure to consult this if you have any questions about using higan.

Lastly, I've added a link to my Patreon page (https://patreon.com/byuu/) to the higan downloads page. The money will go exclusively toward purchasing SNES games for preservation, hardware and flash carts for reverse engineering, equipment such as backup drives, etc. Donating is entirely optional and comes with no rewards, but would of course be greatly appreciated! ^^;

I heard someone found a bug that would trigger on a real snes but not on any emulator (including higan). I think this release fixes it (and probably triggered it being released early so byuu could see if the fix broke anything).

GBA and WS emulation are really good. Dunno about NES as I use Mesen which is awesome.
 
DiamondDog74 said:
Yes! My favorite! Love how much care is put in this. So is there a retroarch package for the update?
Click to expand...

No, I assume because one of the retroarch devs is a bit of a turdburger and has been insulting byuu for years for god knows why.

I prefer individual emulators so it doesn't really affect me.
 
I wish there was a port of the latest Higan for Mac OS X. OpenEMU comes with a Higan core, but it's an old version. Maybe I'll set out to make a port with a simple UI for it when I find the time.

/edit: Oh, just saw in the changelog that there already is a UI?
 
Became a patron. Had no idea how much this emulator actually covered until I read the thread. Thanks for keeping updates posted.
 
my experience with the standalone version of higan is as follows:

sync to audio- no vsync causing huge amounts of screen tearing due to the snes video timing being slightly faster than the 60hz refresh of my lcd.

vsync- no screen tearing but now the audio is not correctly in time so crackles and pops

sync to audio with vsync- no screen tearing but audio is even worse than with just vsync

so unless you have a g-sync monitor the dynamic rate control in retroarch is the only way most people will play bsnes / higan without the above issues. luckily the bsnes core in retroarch isn't too antiquated and has had several of the updates backported but I wish someone could maintain the reroarch core properly, don't think its going to happen though.
