I know this is an old topic but I wanted to revisit it. At one time I owned a battlesphere gold and like many things in my collection , I sold it. I don’t think I even owned a jag at the time. Now I have a jag and gamedrive so I can play the rom. This might be frowned upon but I have been trying to piece together a complete battlesphere gold. After selling mine I did buy just a game cart : maybe on Etsy , I really do not remember. It was several years ago. I now have secured the overlay, manual , manual adendumn and inner tray. I am waiting on the reproduction box to come in the mail. It will make me feel a little better having it on my shelf and even though it’s a reproduction of an unreleased game, it still plays and will look almost like the original.
