A few searches for Rockman PCE netted me his
site. I believe all three of his repros are pressed discs.
Looking at the pictures it seems he did at least put some time and effort into making the manual, cover and posters.
Edit:
Looking at the Sapphire one is pretty tempting. Is that one of those game that is famous more because it is rare or is it actually genuinely good?
Arcade shooters are not my favourite genre, so I don't play many of them but I do make an effort to play the really good ones. I liked Blazing lazers at least, and I've always had a love/hate relationship with the R-Type series.
Is Sapphire worth that price?
