try a lower lowerpc frequency
to run at 166mhz for step 2 games requires a very fast cpu

Currently there is not. The way it's emulated would mean upscaled textures would be quite hard.
Replacement, yeah theoretically possible.
Probably also possible to patch the roms to replace the textures

according to matthew .. the issue is something to do with vblank
basically the game never updates the palette
it has some some check that if it's in v-blank it'll upload it, if not it never gets updated

Some sort of timing issue

Looks really good. Add a super sampling option:)

Are you using a laptop? Sometimes laptops can only get full performance if plugged into the mains as you can only draw current so fast from the battery

I'll see if I can fix those. Apple is the only vendor that is super strict about signed/unsigned maths in the shaders

If it is just transparency that uses the clamped model it would just be polygon transparency. Poly transparency has 1 extra bit so instead of 0-31 (5 bits) it uses 6 bits where the top bit is basically an enable bit. The range in this case is just 0-32. I think there is a good chance these might use...

I realised when I wrote my super sampling code that I simply used a linear filter when downsizing lol, which means it essentially creates aliasing artifacts. Basically I should have mipmapped the image. Probably easiest to do in a shader this way we could even do crazy things like 3x super sampling ...

Maybe the translator map. I think it's just daytona that uses it, but I'm pretty sure it's just related to texturing. If I remember correctly the 2 daytona versions use a different light clamp model. Power edition is unclamped. I'm pretty sure I did a binary diff between the wheel models on the cars...

It could well be as something as simple as that. Other possibility is some kind of bit in the polygon header but I think that is less likely since we never found any sun clamping bits before.
