The standard issue of the ColecoVision software system artwork file, coleco.zip limits all games to a common, generic bezel. That's how MAME does software system external artwork by default.
This is essentially an expanded version of coleco.zip, that will allow each game (it caters for the 141 games associated with the Bezel Project ColecoVision pack) to display it's own bezel at launch.
Note that this is for MAME standalone only and is not compatible with RetroArch.
Once downloaded, the file MAME Colecovision.zip should be unzipped.
The artwork file in the download is coleco.zip and it contains a generic coleco bezel as well as my multi-view lay file.
The game bezels themselves are not included, due to permission from the Bezel Project to distribute them not sought, so you will need to download the pack and drop the bezels into the artwork coleco.zip yourself.
You will also need to set LaunchBox Custom Command-line Parameters to allow MAME to match the correct bezel for each game. This is explained in the download.
The coleco.zip artwork file will work whether you are emulating using direct media calls (games with the long naming and col extension) or emulating using a software list.
