Compatibility Report

@kisak-valve This needs the label: .Net because the game needs .NET 4.0 Redist

This game require also Media Foundation dlls for cutscenes. Otherwise, it will crash right after displaying the game logo "Fabula Nova Crystallis Final Fantasy".

I used this project for MF dlls : <Link removed by moderator>
After installation of theses DLLS it works flawlessly.
For the moment I still have no clue about the exact requirement.
Edit: @HonkingGoose I will clean my prefix and make a log.

@kisak-valve Oops sorry for that.

Okay here is the log.

There are some trace about MFPlat, MFReadWrite and WINMM.

I think the most interesting part is here :

steam-340170.log

@kisak-valve Just to clarify, I installed dotnet40 using winetricks for this log because of the launcher. If you need an other log with clean prefix I can do it as well.

The game has a regression with Proton 5.13, in previous versions, with installing "<Workaround removed by moderator>" the videos worked, but now when I install the file it only stays black, the good thing is that you can skip the videos and it doesn't crash.

When I don't install anything, before it was only black, now it gets a crash.
Here I leave the files of when I do not have it installed and when I install it.

I select Japanese at audio setting, but cutscenes plays with English audio.

System Information

• Distribution Ubuntu 20.04.4
• Kernel : 5.13.0-51-generic
• Proton : 7.0-3

Should I open new issue ?

I attach log file.

I'm not really sure if this is the right place to post this, if it isn't I can remove the comment.

On the Deck, the game runs quite poorly using the 'Highest' and 'High' AA settings, reaching GPU consumption of around 4-5W for 'High', and 10-13W while not maintaining 30FPS for 'Highest' . I believe the game probably uses some DX-specific stuff that DXVK struggles to convert. 'Normal' and 'None' run fine, but the game suffers from poor AA from the former, and the usual AA disabled choppy stuff from the latter.

One solution people end up relying on the Deck to get AA on games without support is to run the game at a higher resolution. However, FFT0 does not allow you to specify resolutions that does not match your display resolution, and using the 'Game Resolution' option on Steam does not 'fix' that.

I'm not sure if it falls under the 'proton-layer' to tell games what resolutions the screen is, but if it is, it would be great to be able to trick the game into thinking the screen is of a higher resolution to get that AA behavior.

Playing for the first time today, vanilla Proton 10.0-4. Echoing the remarks on ProtonDB, it seems to play well... except for some horrible crackling in the audio.

In the end I wound up (re-)playing and completing this on Windows. Retesting in Proton 11.0 today, things are... weird.

Since I've already finished, I was rewatching cut-scenes from the History section on the main menu. Even though the game is set to use English, I saw a few scenes that were playing with Japanese dialogue. In those scenes, it was the dialogue that was crackling still - the background music was fine, I think. However, in the scenes where English dialogue was played, I didn't notice any crackling.

Further to the language mix-up, some cut-scenes didn't play at all, or if they did, they still had this place-holder or loading/test video:

The language mix-up reminds me of what I experienced in https://github.com/ValveSoftware/Proton/issues/3910#issuecomment-2355034824

I understand that, internally, Type-0 is a mess of a port - a PSP game updated to a PS4 game that's been ported to PC. This was the reasoning I was given for the lack of modification tools, so it doesn't surprise me that - compared with other FF games - Type-0 doesn't fare well with Proton.
