Make Images for other released Arcade cores

[dyreschlock]

There are several other arcade cores that have already been released. I think they have some good images, but I should probably make my own so that my image set is complete with all currently released cores. Then, if someone is switching image packs, my packs can completely overwrite their categories and they don't need to fill in gaps.
