Sometimes, even the creators of a game don’t know what’s been shown of it. 

A little over thirty-one years ago, the Japanese magazine Famicon Tsushin printed screenshots of Sonic 1, taken from the game’s Tokyo Toy Show 1990 build. A few days ago, those screens resurfaced on Twitter, shortly after the magazine was posted to Archive.org, thanks to @VGDensetsu. The screenshots featured a clear look at an unused Sonic 1 beta enemy, from before badniks were created. While this technically wasn’t the first time a decent screenshot of this enemy was found (and blurry screenshots were around in the mid-2000s), it did mark the first time it garnered widespread attention from the Sonic community…and Yuji Naka!

Naka’s reaction was one of surprise: he had no memory of screenshots of the enemy ever being taken. In a tweet, roughly translated by Google, Naka said “I don’t have much memory of putting this enemy on the screen, so it may be a screen I made, but I feel like I couldn’t do that at that time, so it’s a mystery.” Obviously, the usual caveats of relying on flawed Google translations apply here.
