Sonic the Hedgehog CD (Mega-CD prototype; 1992-12-04)/Hidden content
From Sonic Retro
Contents
2nd Sonic
By pressing on the second control pad, a second Sonic (rapidly flickering to simulate semi-transparency) will spawn behind the first one, which can be controlled by the second player. This second Sonic controls identically to the first and can interact with the environment in exactly the same way, however the camera does not follow him. Stray too far from the viewport and the second Sonic will warp back to position of the first.
Any items collected by the second Sonic will be applied to the first.
Unused content
Stage select
A stage select exists in the 0.02 prototype but cannot be acccessed by normal means. By changing XXX, it can be accessed in an emulator, although all options but 1-1-A lead to the time attack screen.
Salad Plain good future
By changing YYY and ZZZ it is possible to access the good future versions of Salad Plain act 1 and 2, respectively. Despite the good future theme existing on the disc (and being used for the "Comin' Soon" screen), the past version of the music is played.
There is no legitimate way to create a good future during normal gameplay, as neither Special Stages nor Robot transporters have been implemented yet.
Unsed Sonic animations
Tons of animations for Sonic exist on the disc, but are left unused as only two acts are playable. Many would be used in the final game, however some are left unused there too.
Slightly different Sonic animations
Some frames of animation are also very slightly different, though in most cases just a handful of pixels separate them from the final game (and are far from obvious).
