This is the Japanese version, but if your Switch is in English all of the text, including the arcade/story mode for both games will be in English! Do not know if this is true for other Western languages. The cartridge contains both games so you will not need a code to download one. Side note, for GGXXAC, the switch button B is the select button while A is the back/exit button. I got confused when trying to select a game mode using A and got taken back to the loading screen. Use button B to select vs, story, arcade mode, etc. GG1 works with button A being the normal select and B being the "back button"
