I haven't found any treasures for a while but now I did!
Bought this old retro game for only 3 euros from a Finnish website called huuto.net .
The website is like eBay but Finnish.
The game is originally from Asia (1993) and it's clearly pirated. It also says on the back of the box "FOR SALE AND USE IN JAPAN ONLY".
I found out that this game is known as "Nigel Mansell's World Championship Racing" outside of Asia.
Here's a video what the game looks like:
