Trizeal (Sega Dreamcast, 2005). This is a great shooting game for the console, it really surprised me when it came out all those years ago. Sega consoles are well known for their collectable shooters which raise in price year by year.
This one comes boxed with the booklet, disc and spine card in good working order.
Please keep in mind that your Dreamcast will need to play Japanese games to run this.
