Copy the romfs file to a folder on your computer and extract ctrtool there too. For the purposes of this tutorial we only need romfs.bin, but other games may require you also use exefs.bin (though I don’t foresee that happening unless you are on a 3DSCFW). But that just means it is easy and we’ll be done in no time! On the root of your SD Card there should now have be a folder with a huge name and two files inside: romfs.bin and exefs.bin. Hey! Welcome back! How was your day while the cart dumped? I hope you had fun, because now we get to do some pretty standard stuff. I do not know the process behind that, so in that case you will have to figure that part on your own)ģ. (if you don’t want to wait you can try and get the dump from other places, or extract it from a ROM file. In the case of Pokémon Y, the game is about 1.8GB. I have a Class 10 SD Card so I guess that might have helped, but who knows. For me the process took about 6h30m but I’ve heard people on GBATemp claiming as much as 12h. After that, plug your 3ds into the charger and go about your day as usual. Then, run braindump and choose your cart and confirm that it opened.
Download and extract the “braindump” folder inside the zip into your 3ds folder. This is by far the most tedious part of the whole process because dumping, as it stands right now, isn’t very fast. Next, we are going to want to dump the game itself to the SD card. In the case of the game Pokémon Y (EU) the id is 00055E00 and HANS even has the courtesy of telling us where in the SD card we will have to place the final patch.Ģ. To figure out your gameid just choose yes in Romfs -> SD and the information will show up a few lines below. When it loads you will be presented with a screen like the picture above. I prefer to do this early to not have to go back and do it later, but I guess you could do it only when you need it. First off, we are going to want to know the gam eid of the game we’re modding for later reference. I'll still get what I can done, to at least have something started to show off.1. Maybe in time, when I get a better computer, could I possibly be able to make progress. SDSME still crashes when trying to import sprites for Trainer Classes, so I'm pretty limited on what I can do at the moment. Only maybe some small pokemon edits, but not much else.
I plan on also making new Trainer sprites for the main characters throughout the journey, and maybe some for the trainers, depending on the limitations of what can be done.Īll in all, I have very limited knowledge of how to do this, so help is more then appreciated I plan on making a new region, new Pokémon, New legendries, basically changing everything, making it feel like a new game, rather then a ROM hack. I'm open to ideas, so if you got some, fire them at me, and I'll see what I think about them. Right now, I'm on the planning phase, as I want to first make the layout of the new region, as well as naming the region. I will be using Pokémon Pearl for the base, and plan on making 2 version, similar to how they're done officially. I've tried making GBA Pokémon ROM hacks, but I'd end up breaking them pretty badly, so I'm hoping I can get some people together to help me out with this. Honestly not sure if ROM hacking is still big these days, but I've decided to try and make a ROM hack.
