My insert decals for my ES were made by Jeff at Classic Arcades.

They are probably the only ones out there, but I could be wrong.

In any case, they weren't very good and I don't recommend them. The issue was mostly with the registration of the outer black rings. They just weren't right.

I also think that some of the letters or numbers weren't the same font as the original game. But it's been several years and I'm trying to forget that process.

Cliffy & I sent a lot of time, mostly him, just painting the outer ring with black paint, using the inner number or letter from the decal. Then clearing over the whole playfield.

Good luck.
