About byuu2019-12-05 07:36:26


I am a computer programmer with 20 years of experience, and I have been employed as a software engineer for the past 13 years. My primary focus is on systems programming.

I'm the author of bsnes, a Super Nintendo emulator, and higan, a multi-system emulator. I have been developing emulation software for the past 15 years, and I have currently emulated 24 systems spanning 12 different architectures.

The current incarnation of bsnes comes from an experimental emulator I worked on named csnes, the best parts of which were kept for bsnes.

My emulators have always been open source, and you can find the source code for them on my GitHub page.

I have also spent the past 8 years working to preserve the complete international library of games for the Super Nintendo Entertainment System, or Super Famicom in Japan. A project that to date has set me back by more than $30,000 US dollars.

I learned my trade through reprogramming Japanese games that were never released outside of Japan. I have contributed to the English fan translations of Dragon Quest V, Der Langrisser, and Mother 3, to name a few.

I have worked on many other projects over the years. Most famously, I contributed my emulation of the relatively obscure NEC uPD7720 processor to an effort that successfully preserved the voice machine used by the late professor Stephen Hawking.

I also create videos related to emulation and games preservation, which you can find on my YouTube page.


Throughout my life, video games have always been a passion of mine. While none of us can live forever, I aspire to at least preserve this slice of my youth for future generations through my efforts.

And it is in that same spirit that I've created, with the aim of helping other emulator developers, both veteran and aspiring, to further this cause.

Working as a developer in emulation has proved a constant challenge that has helped me grow both professionally and as a person, and I feel privileged to be able to be a small part of this scene.
