Textured quads #1

Hi, Very impressive coding! Any tips on using Textured quads? I've compiled mld62 also, but that doesn't run at all for me, but I see you use textures there :)

Off the top of my head:

If you can use textured triangles, you can probably use textured quads too, just add an extra point to your call.
You need to set up texpage stuff in order to use textures.
You should probably use 4-bit CLUT mode just so you can get the extra resolution and some extra tile memory space.

As for mld62, I just built it with gcc 6.1.0 and the text is wrong - I have a fix for that, src/gpu.c, comment out the line that sends 0x000001C0 for the CLUT. If the only thing you're hearing is music, are you sure your toolchain is set up to handle soft floats?

Thanks for the tips. I compiled the flite game and it works fine on PCSXR, I'm using the same toolchain. Only strange thing was sprintf was undefined, so I commented them out

define sprintf //

On No$PSX, I do just get music from mld62 but now I can see the texture on VRAM viewer and it flashes something on the screen and then disappears.

I get nothing on PCSXR tho. Thanks for any help.
