Fills the servers array with all the currently broadcasting servers. This action takes 1 second to complete, but you can optionally provide an onWait() function which will be invoked each time VBlank starts. Most of these methods return a boolean, indicating if the action was successful. If not, you can call getLastError() to know the reason. Usually, unless it's a trivial error (like buffers being full), the connection with the adapter is reset and the game needs to start again. For a Multi-Pak game, place Game Paks (all of the same game) in the Game Pak Slot of each Game Boy Advance SP. For a Single-Pak game, place the Game Pak in player one's Game Pak Slot.

If the TCP GBA falls too far behind, it may reply incorrectly and cause the GameCube to stop communicating. IGN Staff (August 27, 1999). "What's DT, you ask?". IGN.

During discussions in the development channels, bonta noticed that several developers were talking with endrift about potential improvements to the GBA <-> GCN protocol. Figuring that his personal project may be of interest, he decided to speak up and announced that he had been working to integrate mGBA directly into Dolphin. He even claimed that these internal GBAs were compatible with netplay. While we at the blog would love to tell a harrowing tale of narrow escapes and crazy solutions to get things to production, that isn't the case here. Despite our best needling, bonta repeatedly explained that all he did was the grunt work in regards to mGBA integration. Advances in emulation quality between Dolphin and mGBA, along with the historical work done in the early days by shuffle2, skidau, and several others had solved a lot of the problems already. Recent fixes to the protocol from endrift were just the cherry on top. While things weren't changing on the GameCube side of things, the GBA landscape was seeing a paradigm shift. VBA-M was now a legendary emulator that had firmly cemented itself into the annals of emulation history, but a new generation of emulators had emerged. Rapidly, mGBA was improving and becoming a robust, accurate alternative with a plethora of advanced features. As users saw more hardware peripherals supported, many wondered if Joybus support and connectivity with Dolphin would eventually come. It turns out that users weren't the only one interested; endrift also wanted to implement Joybus support and even submitted fixes to Dolphin in preparation for support. Unfortunately, other features and work on mGBA caused things to get delayed again and again. Finally, in 2021, support for Dolphin connectivity was added in mGBA 0.9!

Cariad Keigher's Adventures with an 11,000 kilometre-long Game Boy Advance link goes into detail on how timing-sensitive the protocol is to establish context for a story about emulating both sides of the link: Allows transfer of Pokémon between the games. The Adventure mode is only possible when linked to Pokémon Ruby or Pokémon Sapphire, which makes it possible to play these handheld games on full screen using the GameCube controller (much like the Game Boy Player). If the game is connected by using the Adventure mode and has the "Berry Glitch", it will patch the glitch and display a message on saving.

A select few Game Boy games, such as F-1 Race, supported multiplayer modes for up to four players, although this requires the use of up to three additional Game Link cables and the Game Boy Four Player Adapter (model DMG-07). GBA connectivity has reached a new plateau. With Integrated GBAs, taking advantage of GBA connectivity features is super user-friendly. And because everything works so well, it can be forgotten just how much work went into getting things to this point. This wouldn't have been possible without shuffle2, skidau, and everyone else who worked on understanding the GBA connectivity protocol in the earlier years. And without endrift's work on Dolphin, mGBA, and libmgba, there wouldn't have been an easy way to integrate a GBA emulator to Dolphin without tons of refactoring. And of course, bonta's work can't be overlooked. They are the catalyst that actually made it happen. It's still weird to think that when users ask about playing The Legend of Zelda: Four Swords Adventures on netplay, developers and support staff will finally be able to answer, "Yes, you can."LINK_WIRELESS_QUEUE_SIZE: to set a custom buffer size (how many incoming and outcoming messages the queues can store at max). The default value is 30, which seems fine for most games. As we said before, bonta had previously dabbled in GBA connectivity with Dolphin in an attempt to get netplay working. His disdain toward the flaws and difficulties of the previous incarnation caused him to create a brilliantly simple, yet robust system that fits directly into Dolphin's netplay infrastructure. The hard part wasn't even getting everything to work; mGBA and Dolphin are both deterministic for these purposes and once everything was integrated it worked for free. The main difficulties was hooking various features to the GUI and making sure that Dolphin's netplay could handle how the GBA communicates. There is one rather unfortunate limitation, however. Pac-Man Vs. is a game that heavily relies on passing controllers between different people. Dolphin's current netplay infrastructure doesn't have a way of changing controllers once a game has started. While the game does work and synchronize correctly on netplay, the game's flow is impossible to follow. It is a shame, as the game can be a lot of fun. Note that this is a netplay limitation rather than an Integrated GBA limitation. Our netplay infrastructure just isn't designed for changing who controls what controller during emulation. Legacy and Future of the TCP GBA ¶

The game name that will be broadcasted in wireless sessions. The library uses this to only connect to servers from the same game. Emulation these days is well supported for loads of systems, and I understand that original Game Boy and Game Boy Colour are comparatively simple to emulate.Specifies what protocol should be used (one of LinkUniversal::Protocol::AUTODETECT, LinkUniversal::Protocol::CABLE, LinkUniversal::Protocol::WIRELESS_AUTO, or LinkUniversal::Protocol::WIRELESS_CLIENT). Transferrable Minigames - These games let you transfer detachable games to the GBA. Sometimes it is a bonus NES game, sometimes it's a miniature version of the game you're playing. Sometimes it is... Crash Blast. Examples of games with this feature include Nintendo Puzzle Collection, Animal Crossing, and technically Crash Bandicoot: Wrath of Cortex. Contrary to bonta's insistence that he only did the easy part, let us clarify that his contribution to this cannot be understated. He's dedicated a lot of his time toward the dream of getting GBA <-> GCN netplay working, and while this particular incarnation went smoothly, other attempts in the past didn't. If you're playing a Generation 3 Pokemon GBA game, you'll probably end up in the GBA games more than you will Pokemon Colosseum and XD. While these games are currently problematic with the TCP GBA, they're the primary case of why keeping it around in the future will be useful. As a standalone GBA emulator, the Integrated GBA comes up very short. It's specifically designed around Dolphin's needs and cuts out tons of features that are standard in other GBA emulators. For players 3-4, connect the purple-coloured cable plug to a Game Boy Advance Game Link Cable connector box.
