Sent: Sunday, October 19, 2008 9:01 AM To: submit@mamedev.org Subject: Sound Support for Cosmic Alien Hello, I own a cosmic alien PCB and so I thought it would be a good idea to add sound support to this game by changing the corresponding driver ("drivers\cosmic.c"). I also have recorded the different sound effects as wave - files. I have attached two files to this mail. The file "cosmica.zip" contains the samples (so it can be simply copied to the "samples" folder) and the other one "cosmica_diff.zip" contain the "diff" file taken against the 0128 sources. So you can check it and maybe you want to implement the changes in a further release? best regards T.Bellm
