New Project: Bahamut Lagoon2020-01-21 16:59:58
2020 seems like the ideal year. It's time to finish what I started all those years ago.
For now, a brief backstory and explanation. More to come in the near future as the pieces fall into place.

New Article: The Edge of Emulation2020-01-20 18:04:53
I've written a new article covering the final significant issue preventing near-perfect emulation of the SNES: exact cycle-timing of the SNES PPUs (video generators.) I've also proposed some potential solutions that are beyond my abilities, so this article is also a call for help.

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:

New Article: Safe Browsing2020-01-04 15:47:51
I've written up a proper article explanation for my site explaining my reasoning and concerns for removing binary downloads from byuu.org.
You can read the article here: Safe Browsing
The good news is that I've set up several really great alternatives, so binaries are still very easy to obtain via the following services:
Windows Downloads Removed2019-12-29 11:22:48
Regrettably, I have no choice but to remove Windows binary downloads from my website.
They are being flagged and blocked in spite of being absolutely clean, on the sole basis that they are uncommonly downloaded. Which by definition is going to keep happening every time I release new software.
I've written more on this subject, which you can read here:
Google's Monopoly is Stifling Free Software
But essentially, I believe I need a Windows EV code signing certificate, and I am unable to get one. The BBB has not responded to repeated attempts requesting to register my business with them, which is a pre-requisite for obtaining the certificate. In fact, I don't even know if EV code signing will be enough, Google does not specify how to prevent this warning in the future, but right now it's the only thing I know to try and resolve this issue.
I will try to come up with something, but for the time being, I am afraid that downloads are only available as source code or Cirrus CI buildbot results. I apologize for the inconvenience, but my hands are tied here.

higan v107 user interface demonstration video2019-12-23 17:41:52
I've posted a YouTube video demonstrating how to use the recent higan v107 release.
Hopefully this will be beneficial for folks who prefer a narrated video demonstration to a text post.
You can view the new video here, thanks!
Update: I've also created a higan v107 changelog page to track the user interface enhancements implemented through the higan v107 line. This won't be something I do for every release, but since the goal is to drive v107 development based on user feedback, it seemed particularly important to have this time around.

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:

SNES Preservation Project Update2019-12-12 09:57:29
I'll be partnering with the Game Preservation Society and lending them my complete 1,450-game Japanese SNES collection for the next 2-3 years to perform the difficult task of scanning and cataloguing all of the game boxes. I will still be handling the game cartridges as I have been before. We are looking for information from anyone with first-hand experience on the best method to go about shipping these games from the United States to Japan safely, so if you have any ideas, please let us know, thank you!
More information is available here.
(side-tangent: apparently Reddit has a setting for whether you want your user profile indexed or not. Seems it's set to false by default. Worth checking if you post there and care about that sort of thing.)

About Page Refresh2019-12-06 15:17:41
I've rewritten my about page to be more of a short auto-biography, rather than two or three sentences. If you're interested in that sort of thing, feel free to take a look, thanks!
Company Icon and Logo2019-12-05 07:01:48
Here is the official company icon I'll be using:
And here's the official logo:
These were designed courtesy of fracturehill on Twitter, and are inspired by Ange Albertini's bsnes and higan logos.

I recently purchased a MIDI keyboard and have been learning how to start making music using FL Studio.
Obviously I have a long way to go, but it's impressive that even a total beginner can make something (arguably) listenable after such a short amount of time. I've set up a Bandcamp page for posting songs to. Hopefully with time I'll get better.
If you're interested, I've posted an updated version of my first song, Iridescent, here.

Announcement: Business Launch2019-12-05 06:59:56
The exciting news is that today I'm announcing my new software development business.
For the 15th anniversary since starting on bsnes, I formed "byuu" as a limited liability company on October 14th, 2019. The name just makes sense given my domain. It took a while to finalize all the paperwork and register everything, hence the announcement delay. But everything's live now.
In the past, I've sold a few commercial licenses to my emulator software as an individual, which was not an ideal way to do things from a legal standpoint. Around March of 2018, I began working on developing more performant emulation, which led to both the revival of bsnes and a failed licensing effort, csnes. As a result of the latter, I am no longer interested in licensing my emulators for cartridge players.
Instead, I want to focus more on individual uses such as game publishers wishing to re-release titles from their back catalogs on modern platforms. I am also open to consulting and contractual work in this capacity, so long as there is 100% respect for software licensing throughout any projects I'm involved with. My rates will be much lower if this work can be open-sourced.
If you're interested, feel free to contact me here, or on one of my social media accounts.
So what does this mean for bsnes and higan? Nothing, really. I've already mostly re-developed byuu.org to be more professional, so nothing will be changing. My software licensing remains the same, and I will not be commercializing any contributed work that I do not own copyrights to. I also do not require a CLA for contributing to bsnes and higan, of course.
This move is really just a way to formalize the unofficial licensing of the past, and an aim to be more professional. I can now create a business bank account, consider hiring in the future, etc. An all-around win.
Also unrelated to this, I've extended the registration of byuu.org for the next ten years, so I won't be going anywhere!
Thank you for reading.

New image gallery2019-12-05 06:58:53
I've rewritten the old image gallery with a more modern design that supports grouping images into categories.
This time, I'll leave the real-life photography to my Instagram account for now, because I'm not really keen on writing in-browser rotation + zoom + cropping functionality. It is a long-term goal however for my webserver to be 100% self-sustaining, so that I'm not reliant on any third-party websites for anything I do, but I'm not there yet.

Welcome to byuu.org!
This is the official website for the development of the higan and bsnes emulators, among many other things.
Regrettably, due to moving to a new content management system, previous news posts have been lost, but all other site content remains intact.
