You need game roms. Download some from www.mame.dk and put into your mameboy roms folder. Try downloading dkong.zip first and see if it works. Then proceed with other games :) Some may not work because you will have to find older rom sets. Make sure to put zipped rom file into the roms folder. Keep it just the way you downloaded it, do not unzip it.
'Show all games' list is just that - list of all *supported* games. To play any of them, you have to download rom first.
