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.

Hi y'all.

I'm thinking about modding my OLED Switch, since I barely play offline, so I don't care about online play.

I am pretty handy with soldering iron. I successfully serviced various PS3 and RGHed two Xbox 360s (by "servicing", I mean regularly changed thermal paste, CMOS battery, removed dust), and also their controllers (damned chinese ALPS ripoffs).

I was thinking about buying this RP2040 based modchip from AliExpress:

I like this modchip kit because of the removable USB cable for flashing purposes.

But, I have two questions:

Should I reflow MMC to make good contact for DAT0 pin? I see some people reflowing, some not... As long the D0 pad makes contact, it's good enough. But will this contact make through carry the Switch around? As long as the ribbon is placed and soldered in place, I think it's good enough. What do you think?
For context purposes, is this cable just the HWFly OLED version, but with RP2040 fitted in it?

Thanks you all in advance!!
