As we can read on Wikipedia, Super Turrican was developed by Factor 5 and published by Seika for the Super Nintendo. Factor 5’s Super Turrican plays similarly to Mega Turrican and shares a similar visual style, but the game has a different set of levels and features a freeze beam in place of the original lightning whip. DEC noticed some reference about the beta version of Super Turrican on the Factor 5 web site (http://www.factor5.de/secrets
“On a final note about Super Turrican, if you look at the Enemy Gallery in the game manual that can be brought up by pushing the home button on the Wii-Remote, there are several nasty critters in there that you won’t find in this official retail version of Super Turrican due to memory constraints. We were told to deliver the game in 4 Mbit (512 KByte), the smallest size cartridge available at the time, after finishing it as a 6 MBit title. Not only did we have to cut bits of art in several places, but also a full stage and a feature of the new Beam weapon: Not only could it freeze enemies, but also melt frozen ones, something that the player had to discover in the Ice World and that led into a stage set on a Robot Transport hurtling through the clouds. But it wouldn’t fit – and thus, somewhere, on a forgotten floppy disk, there still might exist the original Super Turrican – Director’s Cut.”

Thanks to BigFred we found that the manual the page is referring to is this one
The one on the upper left is a boss not used in the game but only in Mega Turrican. Next to it there are two fishes. I only remember the red one. I think the metal one is unused. All enemies shows between the head and tail of the alien queen are unused. below it’s tail the monkey-like one next to the little fly is unused. So is the red bodied robot in the middle, the brown colored flying monster next to it and the little one on it’s left. Finally the face on the lower left corner and the red one on the right which was instead used in ST2.
There is also an unused boss music in the sound menu of the retail version (the SNES-version of Amiga’s T3 boss sound used in the 2nd scrap yard level).
Factor 5 commented about this at the time when the game was first released in an old video game mag but they did not mention that they actually finished it afair. It was rumored to get a release on Wii as a VC download in 2008 by a member of the NeoGAF forums called “Turrican” who claimed to work at Factor 5.
Thanks to DEC and BigFred for the contribution!
