Snes9x GX Shader support? (blargg NTSC & CRT.OpenGL)

Hey guys, is it possible somehow to user shaders in Snes9x GX?

On the PC version of Snes9x it's possible to combine two shaders to make the game look really old school, CRT televisions curvature and proper NTSC coloring.

Look at this

Scroll down to CRT.OpenGL

And blargg's NTSC coloring is amazing.

So is it possible to use these on the Wii-version, and could it handle it?

Cheers!

Edit: i realized I might've posted this in the wrong section, sorry, can a mod move it maybe?

Most of it would require indirect texture support which is currently missing from libogc.

Edit: Here's an old video of texture co-ordinate warping using indirect textures on the wii: [www.youtube.com]

That's to bad, do you know if it'll ever get done in a near future?

Cheers!

I used it at large scale in this. Perhaps Tueidj meant that it's broken in current libogc or so?

libogc supports indirect texturing.

It only supports tiling or bump-mapping, the functions for warping (which the OP's problem would require) are missing.

GXSetTevIndWarp is a wrapper for GXSetTevIndirect.

The same thing could be said about the other GX_SetTevInd* functions, the difference is they're implemented and documented.

It didn't look so good when I first got it working, seems fine with supersampling.

Edit: You can have fractional bits with a negative scale factor, but then you must use linear filtering.
