Croket! Kindan no Kinka Box (コロッケ！ 禁断の禁貨ボックス！) (2003, Playstation)

Croket! Kindan no Kinka Box (コロッケ！ 禁断の禁貨ボックス！ [...] "The Forbidden Gold Coin Box") is a beat'em up and genre mix by Konami. It is based on the manga Croket! which is about a boy called Croket who is a so-called "Banker". Bankers are people who travel the world in search of magical coins called Kinka (kinka is Japanese for gold coin). Kinkas will supposedly make the Bank Wizard appear, who will grant the wish of any Banker who collects enough Kinkas. Croket wants to achieve this in order to revive his father.
As far as I played, the game is a reworked version of the Game Boy Advance game Croket! Yume no Banker Survial!.
The main game consists of one-on-one fights against other Bankers. You are in a closed area where your opponents are walking around. If you bump into one, a fight will start where you have to knock out your opponent in order to gain some of his Kinkas. There are also treasure chests with additional Kinkas appearing from time to time. Once you have enough Kinkas, you go to the announcer (the game's story involves a tournament) to be declared the winner, and the stage is cleared.
