I have seen that some people have been able to do this but have not been able to find a guide of exactly how. I was hoping someone could point me to a step by step guide of some sort that I can follow.
Thanks, that worked perfectly. I only used the classroom cheat sheet and social link cheat sheet mods but they both work. I am going to play around and see what other mods will work.I dont have personal experience with this exact game. I did have success with modding P5R and I was planning on modding P3 before I learned of the remake.
From what ive read the three games should be pretty similar to mod. I would try using this guide but use the tittle id for P4G : 010062B01525C000

Hi, I'm sorry but I'm getting a bit confused here. I'm trying to add the P4D Specialist over specialist mod. I already extracted the content files from the cpk and now I'm with a lot of folders. At step 3, you said "Extracted the relevant Persona 4 Golden (64 bit) PC mods to the extracted data_e.cpk folder. (overwrite and replace)" and that's where you lost me. Which folder should I extract it to? and the mod that I downloaded came with 2 files called ModConfig.json and Sewer56.Update.Metadata.json and a folder called "FEmulator". Which of these should I extract and where should I extract it to

Great thanks for the help. So the only issue is I don't know where to put the mod files inside the extracted data_e.cpk . Like, do I just copy the FEmulator folder and paste it inside anywhere? Because it isn't in there so do I check in data.cpk to see if it is there?Hey, so I spent some time working on this myself and any mods that don't involve .bf/.flow merging via Reloaded II can be ported to Switch. You just have to pack them into your data_e.cpk, I made an example mod with some instructions: here
If a mod changes something that isn't IN data_e.cpk, it's likely in data.cpk as that's the base Japanese game with data_e being the English localization files. You can put anything in data_e.cpk and it will load at a higher priority.

Those .json files are for Reloaded II mod loader, and are not relevant to this process. FEmulator is part of a folder structure for the mod loader to introduce files. It depends on the type of mod but generally speaking if the mod just replaces a file without any changes via bf/flow merging or executable altering, you can just throw everything into your unpacked data_e.cpk and repack it via CRI file manager.
For example, this mod for Floating Shadows works fine (I did an entire playthrough with it running) because it's just a file replacement, where as something like Dungeon Save Points would not work because it uses bf/flow merging. I'm sure it would be possible to get Reloaded II to work with the Switch version but that's a little out of my scope of possibilities right now.

If the mods are just simple drag and drop and the Switch version uses the same file structure then you could just have it replace game files and such using LayeredFS.I have seen that some people have been able to do this but have not been able to find a guide of exactly how. I was hoping someone could point me to a step by step guide of some sort that I can follow.
So the data.cpk is really heavy but data_e.cpk shouldn't be more than 1gb.Thanks again for the information. I don't actually have any specific mod I want I just like doing this for fun. I was able to port the PC versions of 2 other mods for persona 4 Golden PC over to switch and they worked but then I could not help with the other persons request. As you saw he wanted the P4D Specialist over "specialist" mod but I could not advise him exactly how to proceed as it had different file structure and type than the mods I ported over. All of your information was very helpful, especially with how to unpack and repack the .awb file. I was able to do this and then repack the cpk. But somewhere along the line I must have made a mistake because the resulting cpk was like 15gb lol. I actually think I know what I did wrong now but am fed up with this for now lol so i will try again tomorrow. Might have to pester you with some questions again but I think I already know my mistake. Thanks again!
The mods are drag and drop for the PC version since there's a mod loader that deals with unpacking/repacking files on the fly, the Switch version doesn't have that, so you have to repack your main .cpk file every time you want to run a mod.If the mods are just simple drag and drop and the Switch version uses the same file structure then you could just have it replace game files and such using LayeredFS.
Yea, that is exactly what I did wrong lol. I placed the modified files in the data.cpk rather than creating a folder for them in the data_e.cpk. I know I kind of babbled and asked tons of questions but now hopefully other people with this problem can follow your steps here. Thanks for the help! It is kind of hard to find a neat guide that goes step by step for people who aren't great with computers like me.So the data.cpk is really heavy but data_e.cpk shouldn't be more than 1gb.

No worries! Glad you got it figured out!Yea, that is exactly what I did wrong lol. I placed the modified files in the data.cpk rather than creating a folder for them in the data_e.cpk.

hello sorry to bother but how did you exactly use crifilesstymem to extract date_e.cpk from the DBI folder? i dowloaed it but i cant figure out which tool i need to use in my DBI Persona 4 Golden folder I only have the nsp and an empty folder thereThanks, that worked perfectly. I only used the classroom cheat sheet and social link cheat sheet mods but they both work. I am going to play around and see what other mods will work.
Also if anyone else tries, make sure you rebuild the cpk using the slower CriPackedFileMaker.exe method. I tired the other way and it would crash the game. Also, you can easily dump the romfs using DBI so you don't need to use YUZU. And lastly, I used the 64 bit PC mods not 32 bit. I am not certain but I am guessing only the 64 bit mods will work.
So what I ended up doing was:
1. Go into DBI and dumped the rofms to MY PC. (Just drag and drop)
2. Located and extracted data_e.cpk with crifilesystem
3. Extracted the relevant Persona 4 Golden (64 bit) PC mods to the extracted data_e.cpk folder. (overwrite and replace)
4. Repacked using CriPackedFileMaker.exe
5. Go to Atmosphere/Contents/010062B01525C000 and put the edited and repacked data_e.cpk in the romfs folder. (create it if it isn't there yet)
First of all, excuse my English, I'm not very good at it.To extract the romFS in my case use nxdumptool, it will leave them in the root/switch/nxdumptool/romfs/ folder. Then you just open Crifilessystem, drag the date_e.cpk file into the program and you will get a notice asking if you want to extract it.To pack again just drag all the files into the program and then click the button above to pack.I hope I make myself understood, sorry if not.hello sorry to bother but how did you exactly use crifilesstymem to extract date_e.cpk from the DBI folder? i dowloaed it but i cant figure out which tool i need to use in my DBI Persona 4 Golden folder I only have the nsp and an empty folder there
Dont worry your english is fine thank you so much! Mi problema es que no puedo usar nxdumptool porque no tengo las keys necesarias para que funcione ya que tengo usar Lockpick_RCM pero ahora mismo no puedo acceder a la tarjeta sd desde mi ordenador. Por eso solo puedo usar DBI para acceder a los romFS pero no me aperecen en las carpetas,pero muchas gracias igualmente intentare arreglar el nxdump y seguire tu guia cuando puedaFirst of all, excuse my English, I'm not very good at it.To extract the romFS in my case use nxdumptool, it will leave them in the root/switch/nxdumptool/romfs/ folder.
