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.

Converting NGF files for use on Neo Geo Pocket Color Selection?

I recently got my hands on NGPC Selection and was wondering if anyone had figured out a way to convert the NGF save files used in most NGPC emulators to the BINs required for the compilation. I know each game has its own individual save file, and that the BIN is compatible with both the Switch and Windows releases, but the NGF is stored differently enough that it needs some level of actual conversion rather than just changing the extension or something. If anyone wants to take a crack at creating a conversion tool, I've provided complete saves for SVC:MOTM in both formats to use as reference.

Alternatively, if anyone just *has* complete save files for the collection, that would be cool too. I mostly just don't want to have to repeat the process of grinding in certain games, like buying all the items in Last Blade.
