Portal crosshair

Hello, everyone. Haven't been here in a while, maybe you guys could help me out with this. I've had the Cider port of Portal on my Mac for a couple months now, and I've been enjoying it. I got bonus maps working, fixed the graphics (see the before and after), fixed the font, but strangely, I cannot manage to fix the crosshair. I figured fixing the font would remove that ugly red square, but it didn't.

Can anyone help me with this? I would gladly appreciate it.
