Checklist (we expect you to perform these steps before opening the issue)

I have searched for a similar issue in this repository and did not find one.
I am using an official build obtained from releases or updated one of those builds using its in-app updater.
I have re-dumped the game and performed a clean install without mods and the issue is still present.
I have disabled all patches and cheats and the issue is still present.
I have all the required system modules installed.

Describe the Bug

The base game installs and plays without issue, even with the latest (1.17) title update. However, the game does not recognize any of its three DLC titles once they are installed to the addcont directory.

Note: this game has historically had issues recognizing DLC titles on the PS4 console as well, so this may be an emulation edge-case.

Reproduction Steps

Install base game i.e. Rebirth
Install 1.17 title update
Install any DLC, e.g. Afterbirth
Launch game
Observe that title screen still shows Rebirth, and not Afterbirth as it should

Specify OS Version

Linux Mint 22.2 / kernel 6.14

CPU

Intel i9-14900HX

GPU

Nvidia GTX 4060 / driver 550.163

Amount of RAM in GB

64 GB

Amount of VRAM in GB

8 GB

It seems like the game isn't even attempting to load DLC, there's no calls to anything sceAppContent in there.
Just to make sure, you don't have any log filters enabled, right?

Interesting. That's right, I haven't enabled any log filters.

Just in case, it would also be good to see if your jailbroken PS4 detects DLC.
It's possible the game requires PSN access to use DLC, in which case DLC wouldn't show on a jailbroken console either.

This is just throwing ideas out there though, it's hard to come up with anything concrete for a game that isn't even trying to load DLC in the first place.

Ah yes, good point. Also as I mentioned above, this game is notorious for having difficulties with DLC (see here for example). It could be the same challenge here.
