One day, I found a copy of Sonic CD at a flea market, I was so excited to play Sonic CD. I turned my Sega CD on and i saw something strange about Sonic. It did'nt need or have a passcode and it showed on the title screen of what appears to be Sonic.exe. I ignored it and I played the game as Sonic.exe. I played the first level it was the same as on Sonic CD. Execpt it was quite buggier ands slower than Sonic CD. I knew something was wrong with this game. So i returned it to the store and have them fix it. Unfortunately, they could not see what was wrong with the game. So, I decided to throw this game out in the garbage can and I never saw it again.
