Hey! I recently sketched your pony for my SGC Promise and I have to admit it's one of my personal favorites XD. Well 60 down 40 to go.
To be honest I've never played Sonic 1, I was more a Nintendo kid back in the day. But I can believe that that kind of stuff happend back in the day with consoles, I've played my gameboy advance againb lately with some friends and we played the heck outta telespin with balloo the bear, there was this glitch that the wall dissappeared, so the friend that was playing crashed into an invisable wall and lost his last live :P
