mGBA 0.9.0


Nouvelle release pour mGBA, émulateur GBA pour Windows, Ubuntu et Mac OS X développé par endrift, qui passe en version 0.9.0.
Pour rappel, les GameBoy/GameBoy Color sont également supportées depuis la version 0.5.0.

A savoir également que l'auteur développe en parallèle un nouveau projet nommé Medusa, celui-ci apportant en plus le support de la DS. D'ici la version 1.0 de mGBA, les 2 projets doivent converger pour ne laisser place qu''à un seul émulateur qui sera donc Medusa, et dont la sortie en version 2.0 (initialement prévue pour 2018) semble repoussée. En attendant vous pouvez toujours tester les avancées de ce projet en téléchargeant la version alpha 2 disponible sur cette page.

Citation
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. While 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 changed under the surface, but not many user visible new features. In the interest of releasing an properly exciting new version of mGBA I decided to hold onto releasing 0.9 until it was polished and featureful. During the latter half of the year I finally started a push for features, and released 0.8.4 as the last of the 0.8 line. Remember, mGBA currently only has one major developer, so things can take quite a long time to finish, and if I’m not actively working on it any given week then there isn’t progress made that week. While this did lead to 0.9 being effectively “coming soon” for many, many months in a row, it has led to what I believe to be an extremely polished release, so I’m now happy to announce that mGBA 0.9.0 is done and out.

Though it has dozens and fixes and tweaks under the hood, there are some pretty major features to announce, including full e-Reader support, some new enhanced utilities such as a save type converter and a bug report tool, and more. The most exciting features added in this release are detailed after the cut, along with a full change log.
