Strings like "def c783..." you mention are not HLSL but actually disassembled
shader bytecode and c783 is a float constant register. The warning you get is
thrown by wined3d, complaining that the shader is trying to use an unsupported
register (you have at most 256 float constant registers in d3d9, that's for
shader model 3 vertex shaders) and failing shader compilation.

That is the limit, at least, for hardware d3d devices. Software vertex
processing relaxes many of those registry limits:

. Wined3d doesn't support software vertex processing at the moment though.

What game are you trying to run?
