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.

Switch Lite backlight comes on for Nintendo logo then off - but Lite boots | GBAtemp.net

OK, I have 3 Lites, 2 came in with no backlight at all and one that i blew with a slipped probe while measuring voltages to fix the other 2. All have a new TPS61162 from Mouser, two have all the passives replaced from Switch donor boards and the third has all the original passives.

All do the same thing - the backlight comes on EVERY TIME for the Nintendo logo. Then it does not come on for the switch logo or the home screen 99% of the time. But the switch boots, i can enter home screen with three clicks or touches and then hear the home screen shuffling icons when i swipe across.

And if i use Power button to put it to sleep, then wake it up with either power or home buttons it will -sometimes- light up the home screen! But it is hit or miss - sometimes one will light up every second or third attempt, sometimes it will go 10 attempts and all be black. And it is inconsistent - sometimes its wake on power button that lights it up, sometimes its the home button.

Anyone ever see anything like this? I’d say its the TPS chip from Mouser except all 3 will light for the nintendo logo during boot every single time. Its like the SoC or software isn’t getting an intput it needs…

Any ideas or other experiences would be appreciated
thanks
Dave
