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.

[PoC] ACNH Inventory Cheat Generator

Hi everyone!

I decided to release the ACNH inventory cheat generator (ACNHICG) script I made for myself so everyone can use it.

It allows you to switch between pre-configured full inventories in-game by generating cheat codes for entire custom inventories. Here's how it works:

Download and install the latest version of Python 3 (3.6.0 or newer) (make sure you enable the Add to PATH option and the Install py launcher option if possible/available)
Open it with a text editor, e.g. Notepad++
Download the attached release of the ACNHICG and extract it
Download a copy of the item ID list from the OP of this post (or just use the one provided in the download)
Open the items.txt included in the release, check out the format of items in the inventory you want
Simply put, you just copy the full line of the item you want from the item ID datamine (use Ctrl + F (Cmd + F on Mac) to search) to your items.txt, and append the amount preceded by a space and an x, just check out the examples and it should be clear
Note: Currently, item modifiers other than amount are not supported, but you can still try to make it work if you know what you're doing
Note: You can make groups of inventory cheats by separating them with an empty line (inventory cheats with more than 40 items are split in parts for you automatically)
Note: There has to be an empty line at the end of the file, and commas in item names MUST be replaced by an underscore
When you're done editing items.txt, save and then double-click the inventory-cheat-gen script
Give each of your inventory cheats a name
Done! Copy the generated file to your Switch's SD card (the path is /atmosphere/contents/01006F8002326000/cheats/)

Warning: Avoid enabling multiple inventory cheats at the same time as they are not compatible with each other!

Other than that, have fun! Let me know if it works and feel free to ask questions.

Note that this is intended to be just a PoC and temporary solution until a more sophisticated solution is available. I just got tired of doing all this manually, so I just went ahead and automated the boring stuff!
