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.

duckstation is an excellent Playstation 1 emulator by Stenzek. It has a very good compabiility and it is quite performant. It also supports all kinds of enhancements such as high resolution rendering and PGXP which can lessen the "wobble" and...

Hi, I'm sorry if this is a stupid question, but I bought a Switch Lite and I was surprised to notice that the image quality seemed a little jagged at the edges, "crunchy". Seeing some other people play on the switch lite on youtube, theirs seemed generally smoother so I don't know if mine has an issue or something? Im providing a few screenshots below (open the images at full res, they look cronchy like this on the console too)

Thanks in advance!

It could be a matter of the format screenshots are saved in - jpeg is known for compression
But it could also just be the fact the Switch Lite outputs to 720p only, since the screen is that resolution.

Two factors the compression as mentioned above and also that lack of anti aliasing. For some reason Scarlet and Violet and Legends Arceus don't use any AA leading to lots of jaggies. It's worse for the latter because it tends to render below 720p and due to the more 'realistic' texture artstyle compared to Legends Arceus.
