Parappa the rapper original version

hello my name is evan and about 3 months ago I wanted to buy some new games for my ps1 that I found in my dads basement when we were going to do a garage sale.i asked him if I could keep it and he said yes and I jumped for joy and drove home.when I got home I hooked it up and went on my computer to look for a ps1 game I looked up one of my favorite game from my childhood called parappa the rapper.I only found one listing for it though but it was better than nothing.So I looked at it and it read parappa the rapper original version.but the porice was only 15 dollars I thought that it was strange because the game is really rare.but I bought it anyway,then 15 miunuets later it arrived and I was so happy I opened the case and on the disc it read parappa the rapper original version in sharpie but I didn't mind.i put it in my ps1 and then the cutscene began but it was different.it had parappa in the hospital because he tried to jump over a moving car.sunny funny asked the doctor if parappa was going to be okay the doctor said he would be in a minor coma and then the stage started but nothing happened it was just sunny sobbing for 2 minuets and 45 seconds.then the screen went black and you could hear sunny scream and a gunshot I was confused why was sunny screaming and why was there a gunshot I guess I'll never know.
