Sanyō Pachinko Paradise 4: Sushiya da Gen-san!!

Pachinko Paradise 4 is one of the many titles in Irem's long-running pachinko simulation series. It features reproductions of three pachinko machines made by Sanyo Bussan: CR Sushiya no Taishō P7, CR Sushiya no Taishō M3, and CR Sushiya no Taishō L8. There are two standard modes available: Tsūjō (Normal) mode allows the player to modify a wide range of settings for each machine, while Jissen (Battle) mode challenges the player to win as many balls as possible on the default settings with a limited starting pool and time limit. There is also a View mode where the various animations that play on the in-game display can be freely viewed.

The game includes a simple story mode where the player takes the role of Gen-san (better known as Hammerin' Harry) who travels around his two with two friends, solving problems by playing pachinko. There are also several PocketStation mini-games that can be unlocked by meeting certain conditions in the main game.
