Bubble Bobble: Lost Cave V1.2 [Homebrew]
Bubble Bobble: Lost Cave V1.2 [Homebrew] is a lovingly crafted independent arcade homebrew title first released to the global retro gaming community in 2021, developed by the Old School Games Team and optimized for both vintage JAMMA arcade hardware and modern emulation platforms. Built as an official fan-made expansion of Taito’s legendary 1986 Bubble Bobble franchise, this title follows beloved bubble dragons Bub and Bob as they explore an uncharted, crystal-filled hidden cave system to rescue their captured hatchlings from a new dark wizard villain. Unlike many superficial homebrew reskins, Lost Cave V1.2 adds 130 hand-designed levels, never-before-seen elemental bubble mechanics (fire, ice, and lightning variants that trigger unique area attacks), 7 new enemy types with specialized attack patterns, and a full 4-player local co-op mode, a first for any arcade entry in the Bubble Bobble franchise. The 2022 V1.2 update adjusted level difficulty balance, fixed rare crash bugs on origin

The emulator loads after you press Start Game.
