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.

If I put a few Cheats in EdiZon, it will work well. However, if I put too much, I can't find it all of a sudden. Does anyone know how to do it work even if I put a lot of cheats in?
I used up to approximately 2200 lines.And it didn't work.
Please how to expand the cheat TXT file capacity.

According to some post in this forum, the maximum filesize for Edizon is 32KB.
Another possibility is that there is some error in the input file that breaks the program while it is reading the input.

No, there is no invalid code in the input file. And it works well up to 55KB. However, if the file exceeds 55 KB, it seems that the cheat can no longer be found.
I want to know how to add a new code file or increase the file capacity in the same game.
