Hello. I'm running Rebug 4.84.2 on my ps3. I converted some of my backups folder games to ISO. My question is how can i mod the game? Is it same as folder game (modding the eboot.bin)?

In ISO format all the game files are contained in a single file.
If you need to modify the files you have 3 alternatives:
  • If your mod is simple, like replace a few bytes, you can find the offset of these bytes in the ISO and patch the file without have to extract it. This can be done easily with HxD editor on the PC.
  • If the mod requires to add, replace or delete files, then you have to extract the files in the ISO, make the changes and rebuild the ISO. This can be done on the PC or in PS3 if you have enough free space (2X the size of the ISO).
  • The recommended method (that works for both ISO and folder games) is to create and install a patch PKG with the mod. The PS3 first look for the patched files in /dev_hdd0/game/<TITLEID>, then in /dev_bdvd/PS3_GAME or /app_home/PS3_GAME

Most of the time game mods require the install data to be modded, not the disc (in this case ISO), though there are a few game mods that deal with the disc files.

And some mods modify the game while loaded into memory so again the disc would not be touched 9 times out of 10.
 
I'm thinking to replace offset in eboot with HxD like on folder games. So ISO game will have eboot.bin in dev_hdd0/game/<TITLEID>/usrdir?

You have EBOOT.BIN in /dev_hdd0/game/<titleid>/USRDIR only if you have installed a game update.
In that case, the EBOOT.BIN in the ISO is ignored.

Only if there isn't a game update installed, the EBOOT.BIN in the ISO or in GAMES folder is used.

I've suggested to use a PKG for your mod... Why you do want to do it in a different way?

Because i don't know how to create modded pkg file, but i can add cheats with HxD in EBOT.BIN and use it this way. Also i find it easier to take EBOOT, edit it and transfer to ps3 again.
 
Sorry for bringing the old thread, but i have kinda same question.
I'm on Ferrox CFW and i want to install mod menu on GTA IV which is replacing the update.img file
My quesion is how to:
  • The recommended method (that works for both ISO and folder games) is to create and install a patch PKG with the mod. The PS3 first look for the patched files in /dev_hdd0/game/<TITLEID>, then in /dev_bdvd/PS3_GAME or /app_home/PS3_GAME

    Which tool do i have to use to create patch PKG and how to configure it to replace update.img in my ISO game?

You can use one of the many tools available that create packages:
- TrueAnsestor Package Rebuilder
- lmn7's pkg custom
- Make PKG (right click on folder) using PS3 Tools Collection
- psn_package_npdrm.exe
- make_package_npdrm.exe

The game patches usually have a PARAM.SFO with category GD (Game Data).
 
@aldostools , if I have an unmodified ISO game and I use a translation patch made in PKG, if I install it, would it modify the original ISO? Or it would be loaded on the fly acting like a PS3 Game update? If it's like that, it's very interesting.

probably not but maybe you can convert iso to jb folder or cfw2ofw format and then replace the modded files from the pkg.
