A friend of mine is going to reproduce Radical Dreamers for me on a japanese SFC cart, so I was playing a little in Photoshop to see what I could do for a label design, and these are the results =D
This is the original design I had in mind, based on the title screen and many other labels floating around the internet:
This is another design I came up with when I was working on the first one:
Opening and ending =)
Here are both PNG files in the original resolution (Photobucket downsized them), and the PSD file if you want to change/add/delete something. Toggle 'Layer 3' to view both designs.
I took the dimensions myself on a Super Metroid label (10,6 cm x 3,8 cm)
I'm no expert, so feel free to say what you think ^^
