I recomend taking off dynamic crosshairs in the advanced options, but they still work with it on.

Just download this zip file:

If you want the blue crosshairs, rename dodcross.spr dodcross.red.spr, then rename dodcross.blue.spr dodcross.spr

If you've made changes to your HUD before this, you should back up hud.txt. If you haven't, I've put a backed up copy of the original in the zip so no worries.

Could you please make a yellow and red one???

red hairs, or red dot?

Ok, there's an update up now with yello crosshairs and a red dot. I've also changed back to the single pixel dot, it seems to be better for non-dynamic mode.

Added a green one too.
