ROM Hack Question Installing Mods For Bloodstained

[magusdavyd]

I managed to get one mod to kinda work by throwing it into a "~mods" folder just as you would for the PC version (except under romfs then BloodstainedRotN and so on). The character's skin texture is modified but the actual model isn't. Any and all other mods don't seem to work at all. I don't think there's a config file that needs to be modified to allow mods. Also, unpacking the .pak files is doable, but I haven't had luck repacking them. Has anyone managed to get any mods (apart from the 60fps) to work on this game?

Clarification:
- there is no special folder for mods. Anything you will put to Paks folder that will be correctly named and according to UE4 sorting will be loaded after main pak will be loaded. ~mods folder just simplifies it for some games. Only exception from this are signed paks, but they are not existing in Switch games

I was hoping you'd see this; you're very knowledgeable in Unreal Engine. You wouldn't happen to know what version of UE4 they used? I'm running 4.24 (definitely not what they used) but I was able to unpak and repak YOUR mod. However, it crashes on boot; so I must not be signing it correctly.

Also, as an amateur developer, I wanted to make some homebrew for the Switch but with UE4. I know Game Maker games can be ported pretty easily by just copying the files over into an existing Switch game made with Game Maker (Undertale being the main one used for this). Any hopes that could work doing a similar method but with games made in UE4?

Edit: Your tool has a version checker, but I could not for the life of me get it to work at all.

It's v4, so Unreal Engine 4.19

Nope. GameMaker games have this advantage that exefs is not made specifically for one game assets, so it can load any assets.
UE4 is making exefs game specific, so it cannot be used in the same way as GameMaker. The same is with Unity.

So I downloaded a quick mod for the game and when I try to open it up in the 1check.cmd, it gives me this.

Edit:I'm also installing 4.19 right now. But the UE version needs to match the .pak version before I can unpak it right?

Ok, so I unpacked the .pak file, and tried to repack it as a patch. Since all the files are modifiers to the game, I didn't delete anything from the lista.txt (apart from the instructions 4.1 - 4.3 in your tutorial). Is this an error due to the UnrealPak,exe being a version mismatch?

Well, i didn't check it with mods made for PC versions. So there is a chance that it may not work with some files.
Share link so I can check.

Share lista.txt, because it looks like content may be wrongly formatted

You may need an account to download it, I'm new here so I cant post links. But its the Halloween skin pack one Nexus mods site.

Also, I did have the format wrong, I didn't add the ".../.../.../" at the beginning of each line. Game runs, BUT the textures are all wrong. I am on an older version of the game so updating my fix it, but I doubt it.

I don't think it will fix it. Switch UE4 games are using swizzle, so textures from PC will not match Switch textures.

I was working on modification to noesis to convert all of them, but I have abandoned it some time ago, so it works only with DXT5 and RGBA8. Still there are some resolution shenanigans. So it's the best to work on Switch textures and modify them to look as on PC mod and convert them back.

Interesting, so my best bet would likely be to extract the game, find the textures i want to replace, modify new textures to match the original, and then pak those into a new pak?

If you make a project in UE4 and drag the .uasset into the project via windows explorer, it should give you the source file. I'd have to make sure I have the texture and not the material. Oh boy. Thanks for all your help.

It won't, because UE4 doesn't read cooked files.

You're right. I've been in a habit of copying .uassets from project to project. Damn swizzle!

You have every info about it in this thread. Just read.

I tried to replace a model and texture but it’s garbled, I think Switch version use a different texture compression than PC version.

I tried out too, and had the same result
