Hello guys, this is my first post here! I just got a MIG Switch card out of curiosity and I was tinkering with it. For those who don't know, it's used by placing XCI dumps as well as other game specific bin files in the sd card of the MIG Switch, and are obtained from the original cartridge by using an app like nxdumptool. Two of these bin files are mandatory to get the game to boot: Initial Data.bin and Certificate.bin. They stay the same for every cartridge of a specific game. Now, if you want to use an XCI dump from a shady website it's impossible to get it to work without those files. By using the Certificate.bin from another game it has no problem, but this does not count for the Initial Data.bin. So I looked for a way to obtain this Initial Data from an XCI file and read a bit of the XCI file documentation from switchbrew dot org. Here's what I understood so far: The Switch checks if the cartridge is valid by doing a challenge–response authentication on the Initial Data. The Package ID is contained both on the XCI and the Initial Data, on positions 0x110 and 0x0 respectively. The Initial Data hash is on the XCI at position 0x160. It is calculated by doing a SHA-256 hash on the full Initial Data content. So I was wondering, is there a way to to construct a functional Initial Data file starting from an XCI dump? I also tried a reverse approach by editing the Package ID in the Initial Data from another game, generating the Initial Data hash and putting it in the XCI file but is not enough to get the Switch believe it's a real game. Sorry if this may seem stupid but let me know what you think.

Cyberpunk horror game 'Observer' heading to Nintendo Switch

Starring actor Rutger Hauer and released last year for PC, PS4 and Xbox One, Bloober Team's cyberpunk horror title >Observer_ is heading to a Nintendo Switch near you!

The year is 2084. You are Daniel Lazarski, an elite neural detective known as an Observer, whose purpose is to hack and invade suspects’ minds. To gather evidence, you must relive their darkest fears, and, finally, face your own.

The Nintendo Switch port is said to use the unique features of the system, including full Joy-Con support, touchscreen, and the option to play both in docked and in handheld modes. Unfortunately, Bloober Team made no mention about a release date for the Switch version.

The game received quite some positive reviews, scoring 78 on average on OpenCritic and a high 86 on Metacritic (platform-dependent). We also reviewed it when it launched and you can read it in the link below. Did you play >Observer_ before and are looking forward to play this game on the go? Share your thoughts below!
