This is such a old topic, I can barely remember this mambot but from what I remember is that it does not have any screen shots. All it does is redirect the post data back to SMF transparently from SMF Arcade.
As to the mambot working... It was made in 2008 and 3 years have passed since then. There have been some changes in all 3 software packages, Mambo, SMF and SMF Arcade. So it may work or do nothing at all, who knows it is a old mambot. If it does still work I would like to hear about it.
I wouldn't be too worried about installing it though. As with any other mambot you just uninstall it and it is like it was never there before.
