A while ago I went through Metroid following the translated manga guidebook hosted over at Metroid Database. I loved the style of that book and I was curious if anyone knows of any other Famicom guides, manga or otherwise, that have been scanned and translated.
One book that I do know that was scanned and translated was the instruction book for Famicom BASIC. It's extremely helpful for learning the basics of the language. I believe Famicom BASIC V3 is being translated as well.
