Good, i don't think that the problem will be in the blit, i have "rewritten" SRCPAINT and SRCAND using GetPixel and SetPixel, it has yet the same problem. > > Problem 2: Shadows shouldn't have funky colors. As far as I can see, one > SRCPAINT is used for drawing a shadow: > > trace:bitblt:BitBlt hdcSrc=0x83c 83,90 24 bpp->hdcDest=0x834 83,90 30x30x24 > rop=ee0086 If you are interested in some really "funky", run the game with: wine --debugmsg +all igowin.exe &> log and you will see the shadows ;) (yes with a incorrect color) Regards, Carlos. -- ___ _ \ | / Consulting | . |._ _ _| | ___ ___ ___ http://www.andago.com | || ' |/ . |<_> |/ . |/ . \__ GNU/Linux |_|_||_|_|\___|<___|\_. |\___/ _ \ __|\ \ / Carlos A.
