Do you mean Neogamma?
Wiipower seems to have gone awol, he hasn't updated Neogamma in a while
What cables are you using? I have component, seems to work better with those than standard.
Are the isos scrubbed? I tried cubivore 96mb iso and it wouldnt load at all, so I redownloaded the release with and without padding, one .gcm was 96mb and discEX didnt like it, the other was padded to 1.4gb and discEX converted it and it runs fine.
EDIT: Contrary to what I said about wii games not loading for me.... wii mode IS working now, miraculously!?
EDIT2:

I found a Tutorial for you on DM and DML
HERE that tells you how to do it from scratch. Skip to step 6 for DM rather than DML. Hope this helps mate.
