Crosshairs are made in D3D9. As in a direct X 9 overlay, not a crappy form overlay everyone uses these days.
TY lol. The DX SDK is readily available anytime someone wants it.
I will say that even if it turns out like crap, no offense, I'm glad to see you trying to do this on your own. There aren't many of us willing to do so. So long as it isn't leeched I'm glad you gave it a try no matter what it looks like.
