This may be late but I just got some .chd's last night. For Xmas my dad gave me 3 Mame DVDs which have them on it, but I let him keep the discs until last night so that he could copy the stuff for himself.

I've got Area 51, Kinst1&2, Maxforce, VCircle, and Wargods - let me know if you still need 'em and maybe we can figure out a way to get 'em to you. PM me. FYI They're all v.77 I believe.

(I have to admit I don't even know what chd's are...)
(Edit: Of course I had to look so now I *do* know what they are. Looks like I have 'em all - like I said, PM me).
