For those of you having trouble downloading the binaries for MameCE3 and MegaMameCE3 here is another link for you to try:
http://www.geocities.com/mamece_2000/MameCE3v91.zip
http://www.geocities.com/mamece_2000/MegaMameCE3v91.zip

Just unzip and then run the exe inside.
I am also working on a third link for a mirror so if you have problems, hang in there :)
