[greatlrd] 31100: BugFix : Main_DirectDraw_EnumDisplayModes and Main_DirectDraw_EnumDisplayModes4 it did never entry the callbacks loops it was wrong logic check in the begin of the function. This change are base on Kamil Hornicek tykef at atlas dot cz (irc nick : Pigglesworth) patch and once again Thank you Kamil Hornicek tykef at atlas dot cz (irc nick : Pigglesworth) to notice it. and provide a partly fix for it.
