Still on my cellphone but from what I can see, on Gradius logo, blue part it looks like it has some blury or dots.
Bill elliott's and doble dibble I was in need of those two
excellent work, Laser invation looks great too
to redo the logo gradius not going to be good .. I did the best I could with the image of the site .. as did the nascar logo and all cover.. so we found the best picture of screensshots gave only a touch but I can not even do miracles..
I know you can't do miracles

,and you are doing an excellent work with those covers, using the best you can find, but if someone upload a better scan of bill elliott those screanshots could be change. Did you compare the screenshots from the page that a link?
Asking if someone here has a better scan
