byuu v0.8 released2020-02-11 00:03:17
I'm releasing the first official beta for the new byuu emulator today.
This is a new multi-system emulator, which shares emulation cores with higan.
Like higan, byuu is focused on accuracy foremost. Unlike higan, byuu aims to be much more user friendly. Think of byuu as easy mode, and higan as advanced mode, but they are fundamentally the same emulator under the hood. One is not a superset of the other; they are sibling projects.
The goal of byuu is to carry forward the breakout success of bsnes for all of higan's emulation cores, and not just for the SNES alone. bsnes, by being much easier to use, led to a resurgence in support that resulted in several new features, speed optimizations, bug reports, and emulator accuracy improvements. I hope to rekindle the same interest in all 25 of my supported emulation cores with this new emulator.
And frankly, higan's future depends on this project being a success. I am aiming to retire around the end of this year (though it's not set in stone), and I am looking for a new lead developer willing to take over byuu.org, github.com/byuu, and its emulation projects. I would still contribute to the projects on GitHub for as long as I were able to.
I am changing my personal name to Near, and calling my new emulator byuu, for many reasons. You can read the complete rationale here: byuu.org/articles/names. But essentially, these emulators are not only mine: they are the work of dozens of volunteers spanning 15+ years of development. It is perhaps too late, but I wish to separate my personal identity from these projects. I want these emulators to become group projects with multiple developers, and I want them to outlast me if at all possible. With 15+ years and 230,000+ backlinks to byuu.org, I could not see a way to move these emulators to a new domain. And based on it taking 2+ years for higan to become even partially known to the general public, I did not see a viable method of establishing this new emulator in less than a year without using an established name, and the only such name I have at my disposal is byuu. Ideally, I would have kept my emulators on a separate website from day one, but I cannot change the past to correct for this mistake. I mulled over this decision for the past few weeks, and this is the best choice I could come up with. I hope you'll understand. I will also understand if folks continue to call me personally by byuu. I understand it's not easy to change names after 22+ years, and that this will invariably cause some level of confusion. But it can't be helped.
The byuu_san Twitter account, as well as most social media accounts using the name byuu, will be used only for official software development news and updates going forward. Some accounts will be harder than others to migrate, and will take more time and planning.
I have spun off my personal Twitter account and set up a new personal website. Over the coming months, I will be migrating personal content from byuu.org and elsewhere over to my personal website.
I make no secret of the mistakes I've made in the past as byuu (nor will the internet ever let us forget them), and that I'll likely continue to make more mistakes as Near. But for the past two years, I have been doing my best to change and improve myself. I am who I am however, and though I am to be more friendly and cooperative, I won't hide my identity nor unwavering support for my friends. But game preservation transcends politics and ideologies, and I've now separated my work from my personality, so at this point, it is up to you if you want to follow me as Near or not. It's no longer directly tied to byuu.
In any case, byuu is still brand-new, and it is missing several major features including gamepad support, multi-player support, cheat codes, and more. These features will be added in due-time. Sans enhancements like HD mode 7, I am for feature-parity with bsnes, including run-ahead support and much more. The speed is rather limited as well, but I hope to implement scanline renderers and roughly double the performance of each emulator core in the coming year. I am releasing this now for feedback and to try to gauge interest in this new idea of mine.
I hope it will be a success! Thank you everyone!
- v1: support for gamepad mapping and the save state manager
- v2: support for other controller types (mice, light guns) and multiple-players
- v3: support for Famicom Disk System, Super Game Boy, and Sega CD emulation
- v?: support for per-system input mapping, cheat codes, movie recording, and run-ahead functionality
- v?+X: optional scanline renderers for each core to boost performance substantially
- v?+Y: additional emulation cores from outside of higan (PS1, Saturn, N64 would be most promising!)

bsnes v114 released2020-01-08 10:23:58
In celebration of Max completing his testing of the entire SNES library in both bsnes' fast and accurate PPU rendering modes, and all bugs reported now corrected, today I'm releasing bsnes v114.
Unfortunately, I'm no longer able to host binaries here, and so I'm now currently hosting my Windows binaries at byuu.itch.io instead. For webmasters, I would ask that you please link directly to the bsnes page instead: this gives access to other important links, and allows me to repoint download links in the future as needed.
- Official page
- Windows binary downloads
- macOS, Linux, FreeBSD binary downloads
- Source code repository
- fixed an issue with manually created save states that appeared in v113 (corrected as of v113.1)
- added run-ahead support to the libretro target [realnc]
- macOS: fixed an issue with OpenGL shaders [Sintendo]
- added CPU joypad polling override for Taikyoku Igo - Goliath
- added PPU overrides for Marvelous, Super SWIV, Winter Olympics, and World Cup Striker
- added hotfix for Nichibutsu Arcade Classics (even on real hardware, the attract sequence would sometimes hang)
- fixed region heuristics for the Scandanavian release of Tintin in Tibet
- added a heuristic override for Yuyu no Quiz de Go! Go! (the game's title overwrites the mapping mode identifier)
- properly clear overscan region when overscan is disabled (SNES Electronics Test with PAL video mode)
- updated bsnes to use the latest SNES preservation project database (a few dozen more games added)
- reverted gamepak (folder) firmware naming to use architecture name rather than identifier name
- renamed lr35902.boot.rom to sm83.boot.rom for gamepaks
- fixed typo in the GUI regarding the HD mode 7 +/- hotkeys
In case you think I'm being paranoid or histrionic about hosting downloads offsite now:

higan v107 released2019-12-21 16:02:42
It has been over two years and *235* WIP releases since higan v106 was released.
And today, finally, I'm posting higan v107 publicly.
There's just no way I'm going to be able to create a full changelog here, but I will summarize the most important parts:
- added Sega CD emulation (BIN+CUE only)
- added Neo Geo Pocket + Neo Geo Pocket Color emulation
- added MSX + MSX2 emulation (cartridges only)
- added SG-1000 + SC-3000 emulation
- added ColecoVision emulation
- added boot ROM emulation for the WonderSwan + WonderSwan Color
- substantial accuracy improvements to the SNES and Game Boy emulation
- created an entirely new tree-view-driven user interface
Please note that the user interface rewrite is extremely substantial, and I can't stress how absolutely critical it is that you read the user guide before attempting to use this new release.
The truth is, the new user interface is not ready, and without a release to gather feedback, it never will be. The old higan v106 user interface was unable to scale up to the complexity of emulating 25 systems and counting. I spent many months working from the ground up on a brand new paradigm so that I could emulate any system of any complexity using a single unified user interface. I believe a tree view to be the best way of expressing infinite flexibility, but this design is unlike any other emulator out there. And I know very well from experience how much we all (myself included) dislike change.
I believe that it's possible to refine this concept and strike a balance between familiarity and intuitiveness. , but with your help, I believe I can get there. Short of stagnation with v106, this was the only path forward.
If you're willing to give this release a try, I'd welcome your feedback. Please understand that right now, it's very rough around the edges with lots of small bugs and no polish. The v107 line will include many public point-releases as I incorporate feedback and rewrite components to make the emulator easier to use.
If you're not onboard with that, please stick with higan v106 and wait this release cycle out until things are finalized in a future release. Or perhaps skip over higan and check out the newly revived bsnes instead: bsnes is what I'm known best for, solid SNES emulation, in a performant, feature-filled, traditional, easy-to-use package.
As before and as always, higan is my personal research project. I know that it's not for everyone, but if you're like me, then I do hope you'll enjoy this release. It's the culmination of literally thousands of hours of work since v106.

bsnes v113.1 released2019-12-15 17:16:14
I've posted a quick hotfix release for an issue that was causing save states to sometimes fail to restore the state correctly.
I haven't yet identified why the small change I made in the v112 WIPs caused this issue, but reverting it has of course corrected the issue, so for now, I'm posting v113.1:
