Bubble Bobble Lost Cave - A true spiritual sequel to Bubble Bobble is coming via Dave's Retro Forge for the C64!

As if this week couldn't get any better, as after previously announcing the update for Dave Retro Forge's graphically superior version of 'Bubble Bobble Remastered' for the Commodore 64. Along comes this new announcement from the same team that they are going to release at some point in the near future 'Bubble Bobble: Lost Cave'. As in the words of the creator, "For the first time in 39 years, Bubble Bobble on Commodore 64 receives a true spiritual sequel."

Here's the full details. "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. Built upon the technical foundations of Bubble Bobble Remastered, this project represents its natural evolution and completion. Thanks to extensive reverse engineering and custom tools developed internally, it finally became possible to recreate Lost Cave on C64 with a level of accuracy and respect that was previously unattainable."

What to expect :

• 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 pay-what-you-want fan-made project, created by fans, for fans
• The closest experience C64 players have ever had to a true Bubble Bobble sequel.
