NOTES: Metal Gear Solid The Twin Snakes is a Remake of Metal Gear Solid 1 exclusive to the Gamecube, the development studio Silicon Knights is now closed down and Konami will likely never release this game again. To play, we must backup the game from an original physical disc and transfer this to our Steam Deck and Open with Dolphin.

To run Dolphin with Lossless Scaling, we need to download the Unofficial Dolphin Appimage, add this to Steam as a Non-Steam Game and add the launch command for Lossless. In our Dolphin settings, we must change from OpenGL to Vulkan, otherwise Frame Generation will not work.
