Sutte Hakkun GB – Unreleased Nintendo Prototype (Gigaleak 2020) | Custom Game Boy Cartridge

Sutte Hakkun GB – Unreleased Nintendo Prototype | Custom Game Boy Cartridge
In 2020, one of the most significant leaks in gaming history shook the retro community — the Nintendo Gigaleak exposed decades of internal Nintendo files, including source code, prototypes, and cancelled games that were never meant to see the light of day. Among the most fascinating discoveries was Sutte Hakkun GB, a fully playable Game Boy prototype of the beloved SNES puzzle game that Nintendo quietly cancelled before release.
Built in 1998 and compatible with both Game Boy, Game Boy Color, and Super Game Boy, this prototype has been sitting in Nintendo’s vaults for over 25 years. Now, for the first time, you can play it on actual hardware — exactly as Nintendo’s developers left it back in August 1998.
This is a custom-made cartridge of the leaked prototype ROM, ready to play straight out of the box — no emulator needed.
