So 14 years ago I passed by a man selling random CDs on the street. One of them had the PS1 logo on the side and had the photo of Sonic on it for some reason. Being the little fanboy I once was, I immediately bought this game for a whole buck 50, anticipating to play a Sonic game on my modded PS1.
Long story short, I was disappointed that it wasn't what I hoped for. How dare Sega not make a game on its number 1 rival system?!?! Blasphemy!!!!
Turns out it was a CD filled with Master System games. Which probably resulted me wasting time on it more than how much I would if it actually turned out to hold 1 Sonic game. (Rest assured, for It does include the crappy Master System version of Sonic)
Found this CD a few days ago while cleaning up my parents' home.
One thing I should warn you about is that the sound emulation is a bit off. Best played with external good music. For example:
