Well, well, well. If it isn't my old WCNav program hacked together in TurboC and later done up in 32-bit DJGPP. I've been meaning to get around to updating it but since I gave a working copy off to Quarto there's never been a need to...at least he never mentioned it. =) Either way, since there seems to be at least two people (here) interested in WCNav's further development, I'll guess I'll have to dust off the old bits and redo them in a "normal" up-to-date manner. Now there's only one question...OpenGL or DirectDraw? =) Come to think of it dunno if I should use Cygwin+GCC or DevCPP...or heaven forbid VisualC. BTW, MATs are just strangely constructed raw bitmap files...and last time I looked WCNav handled them nicely. Did the version you have save BMP files?
Oh yeah, I forgot to mention that you could always filter the low res gfx to expand them to a decent size...WinUAE has a very nice filter...Hired Guns in 640x480 MMMmmmmm. =P
