The file identified as 01008f701c074000 is the official for the Nintendo Switch version of Sonic Superstars
Add Game: In the emulator, click File > Install Files to NAND... or simply drag the NSP file into the main game list window.
NSP/XCI Files: These are file formats used for digital game backups. An NSP (Nintendo Submission Package) is equivalent to a digital eShop download.
- The term "install" in this context refers to the process of copying this package onto the console’s internal memory or SD card so it can be played.
- Official Context: Legally, this file is handled automatically by the Switch operating system when a user purchases the game digitally or inserts a physical cartridge (which triggers a partial installation for faster loading).
- Homebrew Context: This specific filename structure (Title ID + Name + .nsp) is commonly seen in the "Switch homebrew" or "scene" community. Enthusiasts who mod their consoles often manage these files manually to install games via custom firmware tools (such as Tinfoil or Goldleaf).
Multiplayer: Supports 1–4 players for local co-op and up to 8 players online for Battle Mode.
Local Co-op: For the first time in a mainline 2D Sonic game, you can play through the entire campaign with up to four players.
- Make sure you have the actual NSP or XCI file, not just this string.
- In Ryujinx/Yuzu: File → Load Application → select your game file.
- If you’re using a terminal command, this string as-is won’t work — you’d need a proper command like:
ryujinx-1.1.0 -i "game.nsp"
