Mac Gaming Mods

I have wanted to use the upgrades in Atomical's games (Bigass and Beer Garden), but I have some kind of glitch going on where the radar is a white box and the upgrades screen is blank white with some fields in grey, but otherwise unusable. Any help?
I am running OSX 10.7.5 on an iMac (2006) with an ATI Radeon X1600 128 MB graphics card.
Current version of Halo MD 1.0b29.
Thanks in advance.

You'd have to ask Samuco about it. Can't get a hold of him currently but you can try PMing him I suppose. He sometimes gets on the chatroom, or you can reach him by using his website probably.

Facebook is your best chance of getting to him, or me xD
