Sega Dreamcast shop Console

Product Name: Sega Dreamcast shop Console
I bought this a long time ago at a video game store, it was working fine. It's 11 years old plus the release in 1999. It's 24 years old. It takes awhile to read the disc. It's works fine. But I normally have to use a catch disc to make the disc catch. Normally you can just pop the disc in you know, and it shop reads quick. I did work on it a bit and kinda got it down to the fist time I bought it. I'll include a controller and a vmu. Cables included. Played everyday. The plastic is turning yellow, I can't remove the yellowing.
