A simple Tesla overlay to change the default config JSON (by copying yours) in Super Mario 3D All-Stars that define wich game to boot. You could also erase the custom JSON to boot into the stock "stardust" Super Mario Sunshine ROM.
Make sur to create a Directory /JSON_ROM (at the root of your SD) with your JSON's config file in. You just need to open Tesla > ROM Injection and select the JSON of the game you would launch. It will copy the content of the selected JSON into atmosphere/contents/010049900F546002/romfs/rom.json, doesn't matter if it is already create.
Furthermore, to delete the custom JSON copy, just select the Delete option. This would erase atmosphere/contents/010049900F546002/romfs/rom.json.
Tell me if you have bugs !
- devKitPro for switch (only if you want to compile it yourself)
Note that the project will not compile if you are missing the librarie.
Go to /rom_injection and compile the program with make.
Transfer /rom_injection/rom_injection.ovlto your switch SD card at /switch/.overlays. (The file already exist if you won't compile it...)
