VentureBeat've got some pics of the original prototype PlayStation back when it was a SNES thing

The original Sonic the Hedgehog had some of the most bizarre pre-production stuff I've seen in a while. The makers of the game were bouncing around a lot of ideas about the game in the early days of it's development and it shows with a lot of artwork such as Sonic the Hedgehog as a rabbit, and Sonic apparently fighting demons with Robotnik dressed as a bumblebee.
 

 

 
Also, there's a lot of graphics that were apparently deleted from the final version of the game, these cannot be found on any ROMs but could be seen in magazines and really old game commercials. A good example is this french Sonic 1 commercial which shows Robotnik's chainball rotating and also the spring "stetch" when Sonic runs into them.

And this advertisement which shows some of the unused Sonic the Hedgehog zones like Sparkling Zone and Clock Work Zone. Sparkling Zone also had different graphics than those used in the final game as well and there were UFOs in the background of Marble Zone, I'm not making this up, search and see for yourself. Sorry if I took up a lot of space, this pre-production stuff is interesting I think, the best place to look for it is old vintage gaming magazines prior to the game's release.

Two unreleased NES prototypes recently unearthed:

Chip's Challenge (prototype has no audio, it's not just the video)

Very glad there are still new additions to the Shadow NES ROM-canon. DIZZY AND DAISY GAZED DOWN INTO THE DARKNESS BELOW.
 
edit: It's very cool that when you pet the Witch's cat you two go off and exist in some smb3 staged space for the duration.
 
edit: Man the queen is a dick.
 
edit: Chip's Challenge fucking rocks. "TELEPORTS CAN BE DIRECTIONAL. THE THIEF TAKES YOUR TOOLS. NEW WALLS CAN APPEAR UNDER YOU." I really wanna make a puzzley tile game like Chip's but with nonsensical rube goldberg levels with a choice of multiple stupid win conditions so you can only make progress by floundering around and accidentally activating game systems you don't understand.

Just posted by John Romero - footage from the 1990 DOS Super Mario 3 demo that IFD (precursor to id software) made for Nintendo, who weren't interested in fleshing it out to a full title:

Not entirely sure this counts since it's a fangame, but the DOS version of Sonic Epoch is pretty noteworthy simply for how elaborate it was for the time it was made (most Sonic fangames back then were made in Kilk & Play).

I did a playthrough of the whole thing here:

Thanks! Yeah, fan games are fine, it's just one of those things where there's so many of them out there, it could be a thread in itself.... but ones that are exceptional/noteworthy in any way are definitely welcome
