Here is a little tip for you all.. The core mame engine (which every mame32 build is based off of) supports save states. you can create a save state for a game by pushing SHIFT-F7 then the slot # (which i think is 1-9 or 1-0) and a file will be created in the default sta sub directory. When you're in the game you can load it by pushing F7 then the slot #. You can also auto do this on the command line by using the switch -state <slot #> :nuts:
So you can go into the games you want to be on the screensaver, save a slot at the beginning of the attract sequence, and have them auto load when the rom is loaded.
Then just modify the command line in the screensaver config to always use a specific slot # like so:
-skip_gameinfo -nowindow -noswitchres -sleep -triplebuffer -nosound -state 8
