Hey mate,
I did in the meantime kinda the same trying to do a native one , so got the formulas working and even the compiling done, but then the app did nothing at startup – but I remember that there was something w OpenGL somewhere in this forum.
as said, not really a coder, just trying to follow the steps here and solve problems, so far not fully sucessfully.
(but maybe your library copy could also solve that)
so far I am running now on intel 7.12.8 as it doesnt make too big of a diff for xcom anyway, but always happy to get something newer
but still fun to see, how many ppl still mock around w good old TFTD
cheers,
m
