Thanks Mr. Do! The early G&W:s doesn't require as much work as the later games as the number of segments to ID is lower, the graphics is relative simple (and therefore easier to vectorize), they are single screen games and there's no memory ROM to record and rebuild. The hardest part for me has been to get the the input mapping correct for the SM5A games when writing the MAME driver. Hap has been very helpful there. Hopefully I'll master that some day smile

Only games based on the SM511/SM512 has a separate melody ROM. In the batch of games received from you, unfortunately Mario the Juggler is the only SM511 based game. I will do my best at dumping the melody ROM electronically which will not damage the unit. The melody ROMs that I have read out are marked as bad dumps in MAME and will require either a decap, which permanently damages the unit and requires special equipment and knowledge, or that we develop a better method of dumping the melody ROM electronically.
