The game gathers characters from unrelated titles, each redrawn at the same scale to coexist: a vampire hunter, a Japanese thief, a giant gorilla, a film hero. The exercise demands delicate graphic harmonisation, and the scenery takes up the original worlds in condensed, colourful versions.
The accompaniment plays the same game as the image: each character brings the theme of their original title, rearranged to fit a shared sonic palette. Moving from one hero to another therefore changes the music's register without breaking the unity, and the new pieces act as binder between these quotations.
Complete: box, manual and disc/cart very clean. Lightly handled.

A 1988 Konami Famicom crossover that bundles Goemon, Simon Belmont, Moai, King Kong and other in-house mascots into a multi-character platformer. Japan-exclusive, never ported as-is. The cart enjoys cult status among Konami fans as an early in-house 'all-stars'. Intact boxed CIB with Konami cardboard sleeve and manual is valued, and the Japanese cote climbs steadily, sustained by the crossover's emblematic status.
Is Konami Wai Wai World still worth playing in 2026?
Konami Wai Wai World is the quintessential Konami crossover on Famicom: Goemon, Simon Belmont, Mikey from the Goonies, King Kong and many more meet in a colourful action platformer with varied levels. The fan service is epic, the staging constantly surprising and the character-swap controls carefully designed. Japan-only but visually irresistible, rewarding curiosity even without Japanese. Strongly recommendable today.
