In the case of GameCube to Game Boy Advance connectivity, we are incredibly lucky to have had talented developers from both GBA and GameCube circles create our current protocol for supporting "GBA" controllers. You have to understand two different consoles, how these systems communicate with each other, adapt to latency restrictions, and have expertise across two different projects. This task becomes even more difficult when you consider connecting two different emulators together. Immense audio and video stutter/ lag.Connecting multiple emulators together is a complicated and difficult task.With DSP LLE (on own thread) enabled, speed regularly drops to 90, resulting in audio stutter.MGBA support is immediate on Dolphin's side and even goes back to older builds. Operating systems are required to be 64-bit to run We test drive mGBA with Dolphin to see how various games perform!DSP HLE sometimes results in audio glitches during cut scenes. Other Unix-like systems (such as FreeBSD) may work but are not officially supported. For their ease of use and additional graphics backend options, Windows is generally recommended for most users. Recently, that has started to change as a second emulator has added support for connecting to Dolphin: mGBA! With the latest mGBA releases, you can now use the "Connect to Dolphin" feature to do just that! In addition, mGBA's lead developer endrift has added some key fixes on Dolphin's side that improves stability when connecting with any supported GBA emulator.Dolphin is a cross-platform emulator that runs on Windows (7 SP1 and newer), Linux, and macOS (10.13 High Sierra and up).Unfortunately, this has been delayed several times because emulating the GBA is a big enough task on its own without worrying about connecting to a completely different system.MGBA has a simple GUI for connecting to Dolphin that even provides feedback on if the emulators are able to connect or if there are problems. To that end, endrift has contributed improvements to the GBA GCN protocol on Dolphin's side in preparation for adding support to mGBA. With support for the Solar Sensor, e-Reader, tilt sensors and GBA linking, it was only a matter of time before they tackled GameCube linking. It has a plethora of features and has become the gold standard for quality Game Boy Advance emulation. MGBA and Dolphin ♯or those that don't know, mGBA is an actively developed Game Boy Advance emulator primarily developed by endrift. These fixes affect both VBA-M and mGBA, however, mGBA has some new features and feedback that simplifies GBA connectivity for the end user.
It's a very different experience from the standard The Legend of Zelda: Four Swords Adventures and stands out as one of the more unique games to make use of GBA connectivity.VBA-M connects fine however the GBA audio does not work properly. This fast paced party game has players racing across a multitude of maps with Tetra and other characters from Wind Waker fully voiced and commenting on their progress. This Wind Waker themed bonus mode requires GBA connectivity as each player has their own screen with the main screen being used for commentary, events, and an overview of the map. This is the Japanese version of The Legend of Zelda: Four Swords Adventures and features a special game mode called Navi Trackers. Nonetheless, mGBA's better emulation plays an especially important role in one particular game - The Legend of Zelda: Four Swords Plus. You can also manually connect or disconnect at any time, which can help with connecting to fickle games that don't like to work on the first try.In most games, there's very little noticeable difference between either of the supported emulators. The lag disappears once the game is communicating with the GBA, but this can be a bit annoying. This is because the protocol has no way to differentiate between the GBA game itself being disconnected and other latency or lag issues. A good example of this is in The Legend of Zelda: The Wind Waker, where it will lag heavily when you connect a GBA before activating the Tingle Tuner. There are a lot of issues, hitches, and stutters that are simply a result of the protocol being insufficient for what we need. This issue is completely resolved with mGBA and you are able to play rounds of Navi Trackers without any issues!At this point, it's safe to say we're reaching the limits of the current protocol. This is more noticeable in Windows than Linux, but it should go without saying that once you start adding in actual network latency the system doesn't work very well right now.The good news is that we have a plan, one that goes beyond simply making adjustments to the current situation. TCP has a base overhead that causes there to be enough latency that some games have trouble connecting or remaining full speed while connected even when run on the same computer. Since TCP works over the internet, this does mean you can actually connect a GBA emulator from a different computer to Dolphin to get an approximation of the original experience!. We currently use TCP to communicate between the emulators. Input dropping issues particularly with map screen open on GBA. Final Fantasy Crystal Chronicles - Some connectivity issues. Crash Bandicoot: Wrath of Cortex - Supported. Other titles may work, but were not tested. Current Compatibility List ¶This is a list of titles tested with mGBA 0.9.1 and VBA-M 2.1.4 and the latest version of Dolphin as of this post. If everything pans out, we may even be able to tackle the final frontier of Game Boy Advance GameCube emulation. Pokemon Box: Ruby and Sapphire - Adventure Mode requires latest development builds for some versions of the game. HLE audio is missing some audio features for this game, resulting in some sound effects playing incorrectly. Mega Man X: Command Mission - Supported. Fire Emblem: Path of Radiance - Supported. Pokemon XD: Gale of Darkness - Connectivity issues. No known issues once connected. Pokemon Colosseum - Connectivity issues. Adventure Mode works without issue. Connecting to transfer Pokemon can be touchy. App cleaner mac redditStar Wars: Rogue Squadron III - Supported? Seemingly hidden feature available in multiplayer. May not be possible to transfer Chaos back. Sonic Adventure 2: Battle - Connects to GBA, but will only connect to Sonic Advance if two or more GBAs are connected.
