Model 1 type graphics

Postby ferrarifan » Fri Sep 22, 2023 11:48 am

Hello. Is there a way to disable textures so I can have that Model 1 flat shading look? I've seen a few posts about it but, I don't know if I have to do it through CMD or the ini file to disable textures that way I can play Virtua Daytona USA 2 lol
Ferraris are the most prestigious cars ever made in my opinion. There very delicate and pristine☺️.

There’s no option to disable textures currently, but if you’d like I can create a modified build that will effectively give games the Model 1 look 8-)

okay awesome. Do I contact you for that specific build or is it available on the website?

I've uploaded a build that does Model 1 style graphics here. It doesn't actually disable textures (because doing that in Daytona 2 just makes everything look white), rather it forces the lowest texture mipmap level which in practice makes most textures a single square of the same colour. Also I turned off smooth shading and specular reflection since Model 1 doesn't support either of those.

I probably won't be updating this build, I just did it because it was easy to make with just a few modifications.

Will it be difficult to add model 1 and 2 to Supermodel? :D

It would be a LOT of work... never say never but I currently have no plans to work on this

The model 3 lends itself very well to high level emulation especially with regards to the GPU, because the GPU has a very high level API it's not dealing with registers etc.

The model 1 and 2 boards, they are basically programmable DSP chips, and I believe especially with the model 2 that it can upload custom DSP code to the chips before the games start. That means it can basically change the way how the DSPs work when drawing. The N64 is like this too, you can upload custom microcode. Most games don't, they use standard microcode, but I know some games upload something custom, and high level emulation will break when this happens.
