Have you checked out miniB3D?
I looked at it briefly... It's a worthy project but incomplete...
There are no plans to add shader support to the main release of MiniB3D. It will remain like Blitz3D itself, designed to be compatible with as many video cards as possible.
This was fine before but the day of the standard "VESA compliant" video card have passed. More and more systems have cards which support advanced rendering features... including HLSL and GLSL shading.
