many MAME frontends can be tweaked up for large game images in a 3x3 grid.
You could probably just build your own desktop shortcuts, instead of using a frontend for just nine games. the added benefit to the latter is that you can point to almost any application,game, or emulator w/rom with desktop shortcuts. Anyways, here is a start with MAME32:
-set desktop resolution to 800x600
-set desktop icon size to 72x72
-in the folder list; select "Available" or add your games to "Favorites" as previously mentioned
(right click each game, select "add to custom filter", then select Favorites)
-toggle MAME32 folder view to off
set rom list font to around 15 DPI (depending on preference and length of title)
set rom list view to "large icons"
That should yield something like this:
