The Dolphin author sent me a video of the emulator running the intro of Mario Kart Double Dash, and it looks absolutely stunning!
Keep in mind, it's a video of the intro of Mario Kart Double Dash, it's not actually in-game. Also, the video has been sped up for viewing pleasure reasons. Nevertheless, it's an extraordinary achievement and only a fool would deny the fact that Dolphin is one of the fastest progressing emulators being developed!
Feel free to comment, I assure you the author reads your input.
