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.

Front-page Hacking Updated

SXOS v2.9.5 beta released, supports firmware 10.0.1 and more

Lagging slightly behind the competition, Team Xecuter have been hard at work to see their SX OS continue to be enjoyed on the latest firmware. [prebreak][/prebreak]As well as this, support for the recently released China region Switch cartridges has been implemented, on top of general improvements to online local multiplayer.

You can check out their press release below:

This SX OS update addresses the following things:

Full support for firmware 10.0(.1)
The latest and greatest firmware is fully supported now. This includes compatibility with the minor update released this week (10.0.1)!

Local Multiplayer over the internet (LAN play) updated.
Local Multiplayer over the internet (LAN play) has gotten some stability improvements. This should help with newer games like Animal Crossing. Please keep in mind to use appropriate MTU/PMTU settings, as some games are very picky about the introduced latency when playing over the internet.

Support for chinese gamecart images.
We have added support for playing backups of chinese gamecart (XCI) images. The switch released in Mainland China only has very few cartridges available at the moment, but this groundwork has also been made so we can support playing western games on chinese switches that soon will be able to run SX OS using our new SX Core/Lite product family!

Users of the SX Autoloader should be aware you need to update it as well also, so please check the Official TX Community or their Official TX Chat Server for the updated files from Team [WAIN].
