Not sure if you chose to use the animation i came up with but in case you did, I would like to provide you with a better file than the one posted.
I notice that the ani tool in jemplode does not convert these 32 color animations to 4 colors very well. So I decided to convert them myself. The result is a much clearer animation. The previews may not look great but at least this is exactly what you will see on the empeg screen.
Take a look at this preview and the original file and yoll see what i mean
