Ok, so here's a thing which I'm not sure if it's ever been properly researched or not: Early Japanese Mega Drive manuals were hole-punched. I'm not sure when it stopped - I have the first 3 releases, G-4001 (Altered Beast), G-4002 (Space Harrier II), and G- 40003 (Super Thunder Blade), and all of which have 6 holes punched in the spine in groups of 3. Pretty sure Alex Kidd (G-4004) was, too but don't have a copy to know... So... Did Sega expect Mega Drive owners to put their manuals in binders? Did they sell an official binder? When did this stop? I don't know when this ended, but the next first party title I have in my collection is G-4011 (Super Hang On) and the holes are gone by then. Ditto G-4012 (Fist of the North Star), and G-4013 (Ghouls and Ghosts) Additionally, Third Party titles such as Thunder Force II (T-18013) and Herzog Zwei (T-18023) are punched, so what was the deal with the Third party catalogue? I've always been under the impression that for at least MOST third parties Sega did the cart manufacturing for them, with a few outliers who made their own carts (Sunsoft and EA, obviously, with their completely different cart design, and possibly Namcot and Capcom, too? Who used the generig MD cart design but their own logo on the back?). These early Technosoft games, I assume went through the same manufacture process as Sega's first party titles, but what about others? There was a rumour that if you had a hole-punched Super Shinobi that was the only completely uncensored versions, but as that is G-0019 I find that a dubious claim, and my unpunched version has Spider-Man, Batman and Rambo in it. (...and I'm pretty sure the Godzilla boss NEVER had spines, right?) As Sega Retro is the place for anal attention to detail about this (and I say that lovingly), perhaps it's something worth looking into.
