Switch release: Create Saturn Game NSP by Markus95
Developer Markus95 has released a utility for Switch owners, that lets you create NSP files for your Saturn Games. It’s a simple but useful .bat file for retro gamers out there, that will save you a bunch of manual steps.
This will let you enjoy a bunch of Saturn titles, in full screen, on your Nintendo Switch.
The script also includes a few options that let you run the games in full screen, customize the wallpapers and boot logo, as well as run games that require more than 4MB memory. The developer notes that not all games are compatible though, so you’ll have to do a bit of trial-and-error with your Saturn games.
Requirements
Before running the tool, you will need the base NSP COTTOn Boomerang – Saturn tribute (google is your friend), as well as your prod.keys file (which you can get with a tool such as lockpick if you don’t already have them).
You’ll need to put those two files in the tools folder.

I’m a bit confused, do I add the game with just only the bin file or add both cue and bin file?
Doesn’t look so fullscreen to me
Is this one based on the Cotton update which improved the Saturn emulator that it comes with or it just uses the old version of the emulator like some other scripts out there?
The improvements they made with the update to the emulator seems hard to ignore: https://city-connection.co.jp/cotton/en/topics/
All these scripts use the first version of the injector. Is unlikely we see a new injector anytime soon, developer of the original tools on gbatemp wrote this: “The first patch on Cotton has new encryption, from my poking around it’s somewhere buried in the main code/game data is using new encryption per game.
I wanted to look at this release but sort of figured it’s the same encryption/hash checking/maybe I should have waited until they fixed the lag until I said ***.”

Yeah that is certainly hard to ignore. Hope we can take advantage of the PS4 version as well. Thanks didn’t know of thos.
I got the Keys in the proper Location, but keeps saying it is not in the Directory.
Signatures Invalid, Scrolling Name still shows the Base Game, got a couple Errors when Loading after Launching, and stuck at the Sega Saturn Screen.
swinech haha worst tablet ewer
Took awhile for me, but it’s very convenient to create Saturn games on the fly 🙂
I’m getting ‘failed to match key’ errors while trying to compile an NSP, and even if I continue and make the final NSP it still crashes (trying to make Guardian Heroes, which SHOULD be compatible). Anyone know what is going on? Running the bat as admin doesn’t let it detect my prod.keys either
Doesn’t work
Hi Sir, could you show the step how to convert the saturn game to the nsp? since I already put COTTOn Boomerang – Saturn tribute and keys file in tools folder, and put saturn original .bin in the game folder, but it still failure, please help and thanks!
