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.

So I went and installed the RetroArch NSP into my EmuNAND and updated the files to the latest version. Was hearing that for NES emulation, Nestopia UE was considered the best, so I downloaded that core. While games run fine, the audio has a crackling sound to it. Not just that, but almost like a reverb of said crackling when audio is silent. This is very noticeable in the intro to The Battle of Olympus. Was able to fix it with changing the audio driver from "switch" to "switch_thread", but was anyone else having that issue with the non-threaded version, and should I stick to the threaded version? This seems to happen with both docked and portable modes.

Also, in at least one game, in my case it's Mega Man 2, I'm finding with Nestopia that the volume seems to fluctuate, that it fades between normal playback and a noticeably, yet subtle, quieter playback. Trying other games, but I can't really notice it. Is this normal? This seems to only happen to portable mode as far as I can tell.
