Do not know why, but some games NeoGeo not display the artwork (some for nothing and others only during the game, but without the possibility of achieving the snapshots.)

If you are interested in this work (especially Mr.Do... ) you can download all these files (76 zip - 23Mb) here: http://www.progettosnaps.net/dwn/pS_artworks_adapted.rar
