Time sure does fly, huh? It’s been 10 years now since the very first commit to the mGBA git repository. And while you can read all about the early history of mGBA on the timeline page, I can assure you I had no expectation I’d still be working on this ten years later. But here we are, a decade later, and I’m still working on it. I can say for sure that things have changed a lot since I started mGBA. Back in 2013, I had only been out of college for a year and change, had just started my career, and this was a hobby I’d had on my mind since before I’d graduated. The intended scope was much smal ..read more

Been a bit, huh? It’s been 10 months since the last minor release, and over a year and a half since the last major release, but progress definitely has not stopped in the meantime. Although a lot of the changes in this version are under the hood, cleaning up a lot of older code, paying down technical debt and fixing bugs, there are still some major new features in this release. Maybe we spent a bit too long on the polish, though, since this release was intended to be released months ago. Note also that mGBA is written primarily by a single developer, so at times progress can stagnate; after al ..read more

After the seemingly longest year possible, mGBA 0.9.0 is finally here. It’s been a difficult year for the entire world and that definitely had an impact on development this cycle too. As progress marched on with mGBA for the first few months of last year, I was able to release 0.8.1 through 0.8.3 picking up most of the bug fixes I made along the way towards 0.9. After several months there were lots changes under the surface, but not many new user-visible features. In the interest of releasing a properly exciting new version of mGBA, I decided to hold off on releasing 0.9 until it was polished ..read more

A new release of mGBA, version 0.8.4, is available. This version is a bugfix release, which contains many stability and accuracy fixes. Notably, an issue in the 3DS version that would lead to the 3DS crashing when exiting the emulator, and an issue that would lead mGBA to appearing in a language other than English by default on macOS despite the system language being set to English, have been fixed. The previously mentioned bug with Advance Wars is still present in 0.8.4. It has also been discovered to affect Final Fantasy I. This can be worked around by using a dump of the official BIOS, or u ..read more
