Hacking Major_Tom Explains Game Dumping/Mods on 3.60

[Cinnamon]

maybe i'm a bit confused - when do we use the standalone moleculeshell and when do we use the one we install to the game?

Use the one we embedded into the game to decrypt only (read-only access).
Use the standalone to install to the patch folder(Read-write)

thank you!
and accessing savedata is only possible using the one embedded to the game?
or, we can access the savedata of any game using the standalone version?
(i'm not really interested in decryption anything yet - i just want save data)

You need to decrypt them so only the one embedded into the game can access the savedata0: folder. Though here you also have read-write access (naturally).

The savedata0 folder will also just hold the game's savedata.

Some games can also access others (hint hint).

what kinds of games/apps can do that?
so, we can install molecularshell to games like this, and access saves of other games without having to install molecularshell to each one? that sounds great...!
again, thanks for the help.

Only some special games can do that and they only have access to specific games' savedata sadly.

So you're saying you've now successfully edited textures?

Well yes and no. I looked at some prepackaged pc mods and the folder of textures they were editing were different ones than the ones I edited fit the character i wanted to mod (if that makes sense). I went back and re-edited the correct textures and now the game hangs on a black screen when the relevant texture should be applied. So it looks like it's trying to load. Might be a similar issue guys were facing with the undub. Will test more tonight and post back.

Well yes and no

You might want to consider confirming that your cpk repacking is working properly using an already existing texture from the vita version.

All the vita character body textures are 512x512. What I would do is say swap out Neptune's Vita body texture with that of another character. Obviously it won't match up properly and will look absolutely terrible but by doing so you can with certainty confirm that texture replacement is possible.

If it works you prove that you're properly repacking the CPK and that texture replacement is possible.
If it doesn't work you're confirming that there is either something wrong with your CPK packing or the game has checks that prevent texture replacement.

That's a possibility I hadn't really considered. Tho I did check that the original cpk and edit had an identical number of files, correct alignment etc. I have yet to get home and test extensively but I'll get back to you on it and let you know what I've tried and the results.

I've been trying to get this undub to work for the past hour but I can't get the game to dump because it sends me to the game instead of molecular shell.

Is there a way to solve this issue?

What are you working with? Game, digital/phys, does it have grw0: if phys, that sort of thing.

 

[pastaconsumer]

I need some help with modding... How do I apply my modifications via the patch folder?
EDIT: To be more clear, I edited some dialogue in one of the LUA files in the first chapter.
EDIT 2: The game is a Cartridge version and is gro0:/app/PCSE00708

Same as the above:

[pastaconsumer]

Same as the above:

Working with Physical version. In my case: gro0:app/PCSE00708 (when I decrypted)

 

[Cinnamon]

Working with Physical version. In my case: gro0:app/PCSE00708 (when I decrypted)

In that case you have to apply the mod through the patch folder where the modded files goes into folder mimicking app0:
Example: Persona 4 Golden has a folder named "data" which contains the data.cpk. Thus the placement of modded data.cpk goes ux0atch/[TITLEID]/app/data/[data.cpk]

Then you have to modify the param.sfo which you dumped from gro0: not app0: to raise the version level and transfer it back. Some1cp has a good guide.
Use moleculeshell sce_sys as a base and transfer param.sfo from your game into it.

Good luck modding!

Thank you so much! It worked flawlessly!

Spoiler: The test

Hello everyone I'll be asking some real noob question here so bear with me, I've trying to undub my PAL digital copy of Persona 4 Golden for the past 2 days and I still can't do it! I've done everything the guide's says but i think i might've screwed up in the copy back section, so if someone can make a video guide for the undub or tell me what files i need to delete and what to copy in the "Copy Back" phase i will truly be grateful.

 

[demoncatursday]

Deleted- Figured it out on my own

 

[Ciphray]

followed the guide for P4G but is it just me or is the whole editing of app.db and mail app not needed for cartridge games, you simply create or rename the patch\[title id] folder with the molecular shell files after the cartridge is inserted, then run the game icon as normal and molecular opens instead and decrypts the game and save files, same idea for installing the undub files afterwards, simply put the patch folder in

the only complication seems to be with persona 4 golden, it doesn't like the undub files being present while the cartridge is inserted, have to rename the folder while cart is inserted or if system is booted from cold boot while inserting cart, then open molecular shell after and rename patch to it's normal PCSE00120 if you start the game as normal and it works

yet don't have to do this with persona 4 dancing all night, can insert cartridge with patch files in just fine. i'm wondering if it's the mp4 files being present in the patch folder, going to try it without them next

no i think we need the near thing so that the save files are decrypted when we access them via the shell we installed to the game patch - no?
the save files you got without using near each time were decrypted?

 

[Ciphray]

i edited the saves with the p4g save editor and put them back in my game and they worked and changed fine, so i can't see how that would work without them being decrypted

just to be clear i'm still running the game icon with molecular shell booting in it's place and ftping in, so the system still thinks the cartridge is running, it's just starting molecular shell's eboot instead of the cartridge one.

edit: and no change from removing the mp4 files, still have to rename the PCSE00120 folder while I insert the cartridge, then rename it back after inserting,

not needed with dancing all night. but with dancing all night I skipped the whole app.db steps entirely but undub works great and can insert cartridge as I like
