Aemulus unable to unpack base files | Persona Modding | Page 1

I'm almost certain it's because you haven't unpacked the files.
You need both ALL_USEU.CPK and PATCH1.CPK in the folder which is why you get that error when trying to Unpack Base Files.

#

Yeah they're just for launching the game through emulators afaik

#

Like I said I downloaded and set up yuzu and an nsp file just to set up the other too links. It didn't help

Also I never mentioned this bjut I dumped the PATCH1.CPK aswell and that did help either

wheat sleet Nov 5, 2022, 1:11 AM

#

So you have both cpks in the same folder and you still get that error when trying to unpack base files?

short swan Nov 5, 2022, 1:12 AM

#

Yes

#

wheat sleet Nov 5, 2022, 1:13 AM

#

Oh, I think I see a bug in Aemulus. Could you try renaming the extension of both of them to cpk in lowercase instead of uppercase

#

Wait, that ALL_USEU is a folder not a file 🤨

short swan Nov 5, 2022, 1:14 AM

#

Is that an issue? It dumped link that I just assumed it was right

wheat sleet Nov 5, 2022, 1:15 AM

#

Yeah, that is. Since your switch is using fat32 files bigger than 4gb get split up, you need to recombine them

short swan Nov 5, 2022, 1:15 AM

#

Oh ok. Thers 4 files in there

#

00, 01, 02, 03

#

Ohh ok

wheat sleet Nov 5, 2022, 1:16 AM

#

Try running this command in the folder, it should combine them all into a file
copy /b 00+01+02+03 ALL_USEU.CPK

short swan Nov 5, 2022, 1:16 AM

#

My switch isn't fat 32, at least the sd card isn't it's exfat. Should I redump without the split? Or just combine them now?

#

I think the split is just set by default

wheat sleet Nov 5, 2022, 1:17 AM

#

I'd just recombine, it'll take ages to redump and combining it should be fairly quick

Np

Updateing discord on my p.c, I tryed typing by hand but I can't get it to work

wheat sleet Nov 5, 2022, 1:24 AM

#

wdym? Is that command not working? (I haven't actually tried it myself tbh, I just found it on a reddit post...)

short swan Nov 5, 2022, 1:26 AM

#

Cmd said it couldn't find the files

#

Might have made a mistake tho

#

Yeah I just drag it and it copied the location exactly

#

The folder

#

#

Yeah that didn't work. Luckily iv already started redumping without split. I set it up really quick just in case

#

It's nearly done

#

#

Copying to p.c, says about 5 minutes

#

It's a file now so thats a good sign

wheat sleet Nov 5, 2022, 1:39 AM

#

short swan

Yeah, that won't work you'd need to cd into that folder then you could do it
(I realise it doesn't matter now though)

short swan Nov 5, 2022, 1:40 AM

#

Np. Thanx for the help btw. I was littery going crazy

#

Ok it's ready

#

Ill try again

#

It's unpacking this time

#

Says it might take a while

#

Almost 7 hours now and the whole time I was missing 1 file. That so dumb 😢

#

I would never have figured it out without you either. Thank you soo much. I hope it works lol 😆

wheat sleet Nov 5, 2022, 1:45 AM

#

All good, hopefully the rest of the process goes smoothly naothumbsup

short swan Nov 5, 2022, 1:50 AM

#

Just 1 more question. Since it unpacking im guessing this isn't the final product. Do I click build after it finnishes?

wheat sleet Nov 5, 2022, 1:59 AM

#

Yeah, once it's done unpacking you build and put the outputted PATCH1.CPK onto your sd card in the /atmosphere/contents/01005CA01580E000/romfs/CPK folder
Unpacking is a one time thing, once you've done it anytime you want to change your mods you just rebuild and replace the CPK

short swan Nov 5, 2022, 2:39 AM

#

Ok thats perfect ^_^

thank you again for all your help

rather than delete the original message, mark this as solved

short swan Nov 5, 2022, 5:58 AM

#

I deleted the original ages ago. Accidenly double posted. Sory for late reply. Fell asleep. It was 2:40am, only reason I didn't fall asleep faster is because my p.c is noisy. I had an alarm wake me up so I could turn it after it was done, off hence me being awake now

I can't delete this yet anyway as ill still need it later when im fully awake but I don't know how to mark it as solved either tbh it did even now how tags worked when I started. It took me a bit just to get my post up and I did realize I had done it when the original post was posted hence the double post

Anyway. Im going back to sleep. It's finnally quite in my room and the p.c's lights finnally out too

#

Lol 😆

#

I build the PATCH1.CPK

Inside the CPK folder there is also a folder called PATCH1. Inside that is a folder of the exact same name and another EN. And theres a bunch of stuff inside both.

I ignored the folder and just used the PATCH1.CPK but only 1 of the mods worked.

The working mod is mod menu.

#

Is the PATCH1 folder needed? 📂

wheat sleet Nov 5, 2022, 8:15 AM

#

It should just be the cpk that you need

short swan Nov 5, 2022, 8:38 AM

#

Np thanx ^_^

short swan Nov 5, 2022, 9:59 AM

#

Quick update. I found a tool to update decompile, manually update and recomfile the PATCH1.CPK and after testing it. It worked ^_^
