The fundamental distinction between Mainline Dolphin and Ishiiruka lies in the Graphics Backend architecture.

While mainline Dolphin supports these features, Ishiiruka v18 integrates them more deeply into the custom rendering pipeline.

The official Ishiiruka thread is on the Dolphin Forums (though links may be outdated). Ensure you download from a trusted source (like the original GBAtemp or Dolphin forum threads) and always scan for malware, since it’s an unofficial build.

The primary demographic for Ishiiruka v18 is users running emulators on hardware lacking raw CPU power (e.g., laptops with integrated graphics or older desktops).
