Well, the documentation doesn't say anything on this. You suspect that the viewport may be in an undefined initial state ? But on the other hand, (0,0) could be out of the supported viewport location range. Yes, I'm too pedantic. :-) Fortunatly, the doc says : "Not all locations may be supported by the hardware and requested locations will be adjusted according to the xViewPortStep and yViewPortStep fields in the XDGAMode." So while I'm pretty sure that XDGASetMode() would bring us in a good enough state (it does, tested with my path), we are sure that doing the initialization ourself with XDGASetViewport(,,0,0,) won't hurt. You are right, it's safe. Fernand _______________________________________________ Xmame mailing list [EMAIL PROTECTED] http://toybox.twisted.org.uk/mailman/listinfo/xmame
