Famicom character image hunt

[Shrikeswind]

Okay, here's the deal: I have four Famicom-era characters I'm looking for pictures for. What I need are pictures at least 350 pixels high with one-color backgrounds (preferably white, but not required.) Here are the characters and their respective games....

Donbe - Shin Onigashima
Hikari - Shin Onigashima
Goku - Yuyuki
Mach Rider - Mach Rider
Bubbles - Clu Clu Land
Tamagon - Devil World

If anyone has an image of these characters that fits description, please give it to me, alternatively, If anyone knows where I can find one, tell me where. Using search engines is getting me nothing I want.

By the way, I want them in their forms from the Famicom. In the case of Donbe, I want the Disc 1 design, for Hikari, I want her Famicom design and NOT her Captain Rainbow look.

This one is tinier, but I can't find another version of it

The closest thing to an image of the Mach Rider:

Basically, for those characters you have the boxart to work with and that's it. Your best option is to find the highest quality artwork you can and do a clean cutout around it in Photoshop or similar.

Best option is to go to Wikipedia and copy the Japanese names of the games into Google image search. You tend to get boxart, flyers and all sorts.

I'm sure I've got a big image of Donbe knocking around, but Hikari only shows up as a small background character in the art. I did find a flyer the other day for Yuuyuuki that had a piece of official artwork of Chao, which I had never seen before... so artwork for these characters is still out there.

Of course, you could also buy and scan the game covers/manuals yourself

Artwork of the characters can be found, but I fear it won't fulfill your requirements in terms of size and/or background. As Fryguy said, it is helpful to search for the spelling in Japanese characters with Google. Anyway, here's what I found:

Shin Onigashima flyer with art of Donbe, Hikari and their animal friends (scroll down):

The images of Tamagon and Bubbles at IGN are probably fanart (by Fryguy?).
