PKSM VS CTRMap

Homebrew your 3ds and put cfw on it (if you want to have an easy time rng abusing) Download Pcalc Download PKSM Inject the Zeraora event into your savefile with PKSM Download 3dsrngtool on your PC Watch the tutorial from Im a Blisy about wondercard rng

Transporter and bank only work on legitimate games, for unofficial VC, and NDS games you'll have to transfer them to a 3DS game through PKSM https://github.com/FlagBrew/PKSM

Download and install the 3ds Homebrew app "PKSM"

Proof: https://github.com/FlagBrew/PKSM/issues/1055

You can't use Poke Transporter even if you have Crystal Clear on VC. It won't recognize the game. If you really want to transfer your Pokemon and have a different Pokemon game on the system you can use a tool like PKSM and recreate your Pokemon.

In my experience, the best way to cheat in Pokemon is using save editors rather than codes. For hacked 3DS, PKSM is the way to go. For hacked DSi, Pokemon Chest. Both are about the same thing: a combination of Pokemon Bank without needing to connect to the internet, moving pokes between generations, and a savegame editor that can create and edit Pokemon as well as some other stuff in your save. PKSM is the better app since it supports generations 1-7 on 3DS, but Chest runs on a DSi and handles generations 3-5.

You can find out how to install CFW here and get PKSM here. The guide will also have you install Checkpoint which can backup 3DS and DS save files. Cartridges will always show up in the top left corner in Checkpoint though you sometimes have to wait like 20 seconds before they appear for some reason. The save files it backs up go in /3ds/Checkpoint on your SD. If you want to use PkHex to export your Pokemon to files so you can trade them with someone via a chat app, backup, extract what you want to trade, get other ones in exchange, and import them. Then put the save file back and restore it with Checkpoint.

CTR Map - a map and NPC editor (basically the 3DS equivalent to Advance Map)

you should also consider if you want to make a 3DS hack. you wouldn't have to program pokemon-amie from scratch, since it's already in the game. basic functions of 3DS hacks are behind those of DS and GBA hacks, but there are mapping tools, and there are scripting tools as well, so... you probably have enough to actually make something in gen 6? it'll be more work than hacking for a different gen, but if you're willing to program a new feature from scratch in a DS game, you must be willing to put in more work than the average romhacker anyway :p
