- The Cave CV1000 is a 2D arcade platform from 2004, used for bullet-hell shooters, powered by a 133 MHz SH-3 CPU and YMZ770 sound chip.
- It uses a framebuffer with a blitter for graphics, allowing flexible sprite handling with transparency and blending effects, but causing slowdown under heavy load.
- The platform's design leads to emulation challenges due to timing intricacies and variant hardware, as seen in MAME and PlayStation 2 ports.
- Ibara (2005) is a key game on the CV1000, blending CAVE's art with Battle Garegga's gameplay, featuring dynamic rank systems and a special mode for enthusiasts.
- Ibara Kuro (2006) revised the game to align more with typical CAVE shooters, altering controls and rank mechanics.
- The CV1000 was succeeded by PC-based platforms, with Cave's last unique shooter in 2012, marking the end of dedicated 2D hardware.
