it's possible to import sonicDX textures into SA1dc

making this thread because there's a few people who are interested in these kinds of projects

like two years ago i started fiddling with replacing the textures in sonic adventure with the textures from the PC version of sonic adventure dx. i successfully retextured the player character models and egg carrier textures

to do this i used tools from MainMemory, a prominent SA1 and SA2 hacker. sonicDX has a slightly different texture pack format, so IIRC there's two different tools for opening the dreamcast .PRS texture pack files in the dreamcast version and exporting the textures from sonicDX PC version

i remember each individual texture file had to be imported and slightly adjusted manually, which was pretty monotonous. i never returned to it because i tried adding one custom texture and broke the mystic ruins map, i forgot which texture it was and didn't want to start from scratch

but if anybody here wants to give that a try, it is definately possible to have a "DX texture overhaul" version for dreamcast

proof of concept CDI, i'm almost certain this has the retextured sonic model and retextured egg carrier map

maybe someone here can post comparison screenshots

 

Hey there,
you can use these tools to edit the files directly without exporting anything.
Ill attach Noesis for PVR files and VMT TextureEditor for PVM and compressed files (PRS) in here. Noesis can also view and export .nj models.

You can actually also edit the model and replace it completly. Therefore I recommend you to use old software like Win 95/98/NT and a copy of 3d Studio Max 2.5. After creating the model and adding the skeleton... you can use the tool njaconv.exe and some Plugins for 3d Studio Max 2.5 which I also attach here. Those files can normally be found in the SEGA Dreamcast Katana SDK r9.

noesisv417 for PVR:

Hopefully this will help you

 

doesn't need to be that complicated. I just extracted the textures from the sonicDX pack file (i think it was .PLT files), then imported them into sonicDC's .PRS files. all the texture names are the same IIRC. i just had to adjust the positioning a bit, IIRC all the textures need the same value of adjustment.

so for example, you can completely retexture sonic's model without editing the actual model data at all

but i mean hey, if someone wants to do a true total conversion of sonicDX with all of the models, menu backgrounds, etc, go for it. i'd really like to see that project

i'm not going to finish the project, i was just saying i confirmed it works and posted about it for someone else to finish it if they're interested

 

Not complicated at all if you only have to import the texture.
The model editing is optional.

 

exactly, if i came off as arrogant in my response i didn't intend that

 

nah, you didnt ^^

 

@TerdFerguson : with the help of shiva and you know the SA datas better than someone else, you'll be able to replace others pvr textures ?

 

its a simple but monotonous and time consuming process. both sonicDC and sonicDX have the same filenames of their texture packs, but the extensions are different

you open sonicDX texture packs, export the textures, then import\overwrite the textures in the corresponding sonicDC texture pack file, then you adjust the X\Y offsets a bit. when you run the game on DC the DX textures are on the models\maps

the tools by MainMemory have a texture preview so you can see if its positioning is off

other things like the world\map textures probably require testing and adjustment to get them perfect

so its a simple but really time consuming project. i was just posting for someone who would be interested in completing it. but i might be interested in the project if i had a team of 4+ people to split the game up into chunks between each person

 

4 people !

I'm afraid it will be too huge... Even if the project is interesting

 

eh 1 person could do finish it in one week working on it 2 or 3 hours a day

did anybody try the CDI i posted?

 

i can post comparison screenshots if no one else is doing it.
totally didnt saw that in your first post.

 

a good one would be sonic ontop of the building in the first cutscene and the egg carrier outdoor area

 

Not yet but I will fo sure
