I am trying to play some handheld games emulated by MAME. So far I have no issues finding the ROMs for the games, but they are not very playable without artwork/bezel/layer files!
One such example is the game 3 in 1: Football, Basketball, Soccer (f3in1) [Fonas, 1979], but there are many other games like the Donkey Kong handheld from Nintendo as seen in this video - https://youtu.be/7rROtTnuWpY
Currently there are 733 games listed as Handhelds - http://adb.arcadeitalia.net/lista_mame.php?genere=28192&arcade_only=0¤t_version=0&lang=en
But there are also more games that are much better playable with artworks.
Does anybody know a repository from where I can download there artwork, layer and bezel files?
