I got this msg with Clrmame 3.10a when i checked Mame chds:
Wayne Gretzky's 3D Hockey [folder: wg3dh]
chd update needed: wg3dh.chd [SHA1 set | better convert chd to old standard] [found sha1: c12875036487a9324734012e601d1f234d2e783e]

All Chds are converted with chdman 0.77u3 and now tested
with chdman 0.78 they're all fine but Clrmame won't think so.

Why?
