Today I discovered the following tidbits: https://www.sonicstadium.org/2014/11/sonic-the-hedgehog-1%E2%80%B2s-original-intro-ending-revealed-3/ https://www.sonicstadium.org/2014/12/sonic-sega-racing-and-sonic-racing-transformed-concepts-found-3/ Are the pictures on the Sonic Retro database or anywhere on the internet?
If you click on the links, it seems the URL is just messed up. Just chop off everything before the second http and you should be fine. -Edit- At least for the Sonic 1 article anyway. The allstars racing one while messed up the same, does not load.
Yeah I discovered that certain information is there but most I attempted are not. The Sonic 1 art that can load is pretty miniscule too. Does any source have the quotes from Naka and Oshima?
