Dolphin, the free open-source GameCube and Wii game emulator, released new 2509 version today after another 3 months of development.

The new release of this game emulator revamped the settings UI, added some new features, and, it can finally emulate Toy Story 3, Cars 2, and Disney Infinity on powerful hardware at full speed.

It seems that Avalanche Software, the team behind the 3 games, don’t like Dolphin Emulator.

However, we’re going to go out on a limb and say that Avalanche Software, the team behind the Trio of Destruction™, weren’t so fond of us. Not only did they leave crude messages hidden in game data for “hackers” to find, but we also suspect that someone on their team was actively monitoring us.

While Toy Story 3 took a few years to get working, the writing was on the wall for quite some time that eventually it would be solved. So, for Avalanche’s next two games, we believe that they left a trap specifically designed to defeat Dolphin: the dcache suicide pill.

As the announcement said, the team added a trap in the games designed to stop Dolphin from running them in PC or mobile phone. But with the 2509 release, it finally fixed the issue by adding a patch allowing to run the Trio of Destruction™ fluidly on powerful hardware.

Besides that, the release revamped the settings UI, and introduced new “Map and Calibrate” button, allows to simply map and calibrate joystick at the same time.

It also added “Correct Time Drift” option under Advanced setting page. It pursues accurate overall elapsed time by running fast after stutters, which is useful for internet play.

Dolphin-emu 2509 also improved the general performance for Bluetooth Passthrough. It added the ability to load Realtek firmware, when trying to use a Realtek adapter with the feature for the first time.

Meaning now the Bluetooth Passthrough now supports modern Bluetooth adapters, such as TP-Link Bluetooth 5.3 Nano and Asus USB-BT500.

Other changes include:

• Disable Dual Code mode by default for desktop, as it’s unstable and modern desktop PCs are overpowered for Dolphin. Though, there’s an option to turn it back.
• Fix DSP-LLE Recompiler exception that could cause games not booting.
• Add resource manager, which tracks the requests per frame for better performance loading textures, and tracks memory usage to prevent out of memory.
• Load custom texture multi-threaded.

In addition, the Nintendo Switch 2 NSO GameCube Controller is not supported yet in the release, as it’s not fully implemented by the upstream SDL (Simple DirectMedia Layer).

Install Dolphin Emulater 2509

The software website provides official installer packages for Windows, macOS, Linux, and Android, which are available to download via the link below:

For Linux, it’s Flatpak package that runs in sandbox environment. Download either X86_64 for Intel/AMD or aarch64 for ARM64 platform, then install via command:

flatpak install /path/to/flatpak-file

NOTE: Ubuntu does NOT support Flatpak out-of-the-box, run the command below to install the daemon first:

sudo apt install flatpak

For Ubuntu users who prefer the native .deb package, I’ve made the packages into this unofficial PPA for Ubuntu 22.04, Ubuntu 24.04, and Ubuntu 25.04 on amd64 (Intel/AMD) and arm64 (e.g., Raspi, Snapdragon processors) platforms.

Simply open terminal (Ctrl+Alt+T) and run 3 commands below one by one to add PPA, refresh cache, and install the emulator:

sudo add-apt-repository ppa:ubuntuhandbook1/dolphin-emu

sudo apt update

sudo apt install dolphin-emu
