I have noticed that on the wiki page for "Metal Sonic", a number of the sprites in the image gallery, purporting to be from Sonic CD, have red rather than grey eyes. I am aware of no sprites from any official release of Sonic CD featuring Metal Sonic with red eyes. A select few of the sprites also feature Metal Sonic facing left rather than right. My original conclusion was that these sprites must have been mistakenly posted in place of the correct unaltered sprites. But I now wonder whether this was to circumvent copyright laws, and whether posting game assets, such as sprites, qualify as "fair use".

I possess the unedited sprite images, personally derived from the 1996 PC release of Sonic CD using the tool "SCDPspr". I would like to know if I may add these to the gallery in place of the edited images and the extent of copyright law surrounding this issue. Any knowledge or discussion is appreciated.
