The original and officially planned sequel to the popular platform game Bubble Bubble has been released, which is a high-quality fan project that fundamentally reinterprets the Commodore 64 gaming experience.
Bubble Bobble: Lost Cave brings the legendary fan-made arcade hack Lost Cave from 2012 to the C64, featuring 100 brand-new levels originally designed by TAITO as extra content for the console versions — now carefully adapted for Commodore’s beloved 8-bit machine.

The project is backed by Dave’s Retro Forge team (coordinated by Davide Bottino and programmed by Victor Widell), who have already proven their expertise with the Bubble Bobble C64 Remastered version. Lost Cave is the culmination of this technical development.

Features
- 100 new levels from TAITO’s console ports of Bubble Bobble, faithfully adapted to the C64 engine
- Level layouts recreated with arcade accuracy in mind
- Carefully reproduced bubble airflows within C64 memory limits
- Gameplay adjustments to better fit the C64 game engine
- Selected new bonus items straight from the original console versions
- Optional Two-Button Controls (jump on Button 2), just like the arcade
- Remastered visuals, fully consistent with Bubble Bobble C64 Remastered
- A slightly tougher challenge that rewards strategy, skill and experience
- A pay-what-you-want fan-made project, created by fans, for fans

Bubble Bobble: Lost Cave is a hack of the original C64 version of Bubble Bobble, not a from-scratch rewrite of the game, featuring fully redesigned sprites and backgrounds. The new graphics, directly converted from the arcade version, offer greater detail and fidelity to the original look and feel, while being optimized for both CRT and modern monitors, to offer the best possible experience on real hardware end emulators alike.


Bubble Bobble: Lost Cave is a must-have for all Commodore 64 fans. It’s a professional work that pays homage to Taito’s classic.
