mGBA 0.8.0
Jan 21, 2020 – written by endrift
A little late (okay, a lot late), mGBA 0.8.0 is finally available as a stable release. This is a major feature release and includes some highly anticipated features. Notably, the high-resolution OpenGL renderer for GBA games, BattleChip Gate support, interframe blending, and much more. Additionally, it includes over 50 bug fixes and hundreds of other changes. A preview of the features follows after the cut, along with a full list of changes.
High-resolution OpenGL renderer
The most anticipated feature of mGBA 0.8.0 is the high-resolution OpenGL renderer. With this enabled the GBA screen is rendered on the GPU instead of the usual software rendering, which allows scaling up beyond the usual 240×160 resolution without thrashing the CPU. With a good GPU it can even render at 4K resolution. This lets rotation and scaling effects look much cleaner and allows the "mode 7" effect to be even more impressive.
The high-resolution OpenGL renderer is available on Windows, Linux, macOS, and Switch. Enable it under the Enhancements pane in Settings. Performance improvements and bug fixes are expected in future releases.
BattleChip Gate
The BattleChip Gate (and associated Progress Gate and Beast Link Gate) are long unemulated peripherals for the GBA. They hook up to MegaMan Battle Network 4, 5 and 6 respectively and allow access to the Operation Battle minigame, as well as using chips in-game. Apart from use in multiplayer, these peripherals are fully supported in mGBA 0.8.0. Just open the BattleChip Gate dialog, under Emulation, before the title screen comes up to use them. If inserted too late the game may not recognize it and you'll need to reset.
The first time the BattleChip Gate screen is opened it will prompt to download all of the BattleChip icons. This is optional, but recommended. After opening the dialog you can select a deck of chips you want to use and simply click on them to insert them.
Interframe blending
A common effect on the GBA is to do every-other frame flickering. While this is not a new effect by any stretch of the imagination—games have been doing this for decades—it only works well on screens with ghosting. On old console games this targeted phosphor fading on CRTs, whereas on the GBA it targets the LCD panel's ghosting. However, most modern LCDs have a much better response time, and sometimes the framerate isn't perfect, leading to visible flickering. As such, a long-standing request for mGBA has been
interframe blending. While ghosting has been possible for some time now with shaders, it was never single-frame and baked into the frontends. In mGBA 0.8.0 every official port received a single-frame interframe blending feature. Some examples of the effects of this feature are seen below.
In this example, Golden Sun jitters the world map to provide a temporal anti-aliasing effect.
Many games flicker parts of the screen to create a semi-transparency effect. Here F-Zero: Maximum Velocity flickers the minimap.
Frame inspector
The new frame inspector feature in mGBA 0.8.0 allows for advanced dissection of rendered frames. By replaying the rendering of a single frame with settings tweaked it lets users figure out which component of a screen is rendered where on the screen, disable specific layers, or even select sprites. Disabling scanline effects also lets users see tricks that a game employs for more advanced scenes. These tweaked versions of a frame can be exported to a PNG if desired.
The frame inspector showing off a highlighted sprite and several HUD sprites disabled.
Currently only GBA games are supported in the frame inspector. GB/C games and more tweaking features will be added in later versions of mGBA.
And more…
Some smaller and experimental features were also added in 0.8.0:
- mGBA now has Discord Rich Presence integration for displaying the current game you're playing. Turn it on in the Interface panel in settings.
- A work-in-progress "XQ" audio feature that works with most GBA games is included in the Enhancements pane in settings. It's a very early WIP and not production ready but may work decently with some games. It also does not work yet with A/V recording due to implementation limitations.
- Support for loading a few additional cheat code file formats. However, VBA .clt files are still not supported at this time.
- Several smaller debugging features, such as an improved map viewer, an improved sprite viewer, and memory range dumping.

mGBA 0.8 beta 1
Oct 20, 2019 – written by endrift
After far too long in development, mGBA 0.8.0 is almost ready for release. While there are still a few missing features left to finish, I didn't want to hold up 0.8 that much longer. While I'm working on those last features I'm hoping a final push for testing will help flatten out any more serious issues before the final release of mGBA 0.8.0, so I'm releasing the first beta for mGBA 0.8.
Some notable new features of mGBA 0.8 include:
- A high-resolution hardware renderer for enhanced GBA graphics
- Discord Rich Presence support
- BattleChip Gate emulation
There are also several smaller features, some incomplete features, new debugger capabilities, and more. While mGBA 0.8 beta 1 is relatively well tested for a beta, I encourage heavy testing before deeming this a stable release, while I work on the last few features. The final release of mGBA 0.8.0 will hopefully be within the next few weeks.

mGBA 0.7 beta 1
Sep 24, 2018 – written by endrift
While it's been long enough since mGBA 0.6.0 came out that the release of mGBA 0.7.0 has seemed like it may never happen, I'm glad to say we're finally reaching the end of mGBA 0.6's time. Due to significant life changes, not the least of which is getting a new job with a long, tiring commute, I've not has as much time to do serious feature work. However, there have been plenty of changes, fixes, improvements under the hood. Though mGBA 0.7.0 is almost ready I'd like to see a signficant wave of testing and bugfixes before I deem it stable. As such, mGBA 0.7 beta 1 is now available, and hopefully the release of mGBA 0.7.0 will be out within a week or two.
This time around the biggest areas of change are not new features, but rather significant improvements in existing areas. Please focus on these while testing and report any and all bugs on
GitHub or email
[email protected].
- Game Boy audio has been revamped. It may not sound correct in many cases and narrowing down which cases are reliably broken will help fix them.
- New Game Boy peripherals are supported, including the Camera, Printer, and Super Game Boy. Additionally, several new mappers have partial support.
- Debugging tools are improved, including a map viewer, conditional breakpoints, and symbol loading.
- There are now translations for Italian and French that are not well reviewed and partially incomplete.

mGBA 0.6 beta 1
Jun 29, 2017 – written by endrift
mGBA 0.6.0 has been long delayed. It's dense with new features and unfortunately not all of those features are hugely well-tested. However, it's almost ready for release. Before a stable release, more comprehensive testing is needed. In the getting out what's already working and promoting testing, mGBA 0.6 beta 1 is now available. The final release of mGBA 0.6.0 should be out within a few weeks.
The following features are either new and not very well tested or heavily revamped and in need of more testing. Please focus on these while testing and report any and all bugs on
GitHub or email
[email protected].
- Game Boy support got some pretty serious changes and may be buggy in some cases.
- The new debugging tools, such as the command-line debugger and the sprite viewer, may be prone to deadlocking or crashing.
- The library view is quite new and not heavily tested yet.
- There are now translations for German and Spanish that are not well reviewed and partially incomplete.
