The 1989 version of 3D Block is credited to Hwang Shinwei himself, not to RCM group. The game does not work correctly in emulators, as it expects some rather strange scanline IRQs. I would like to try my hand at getting the game to work, but lacking the actual cartridge, I would need at least a real-hardware (with real cartridge) video of that version in action to know what kind of scanline effects I should be getting. Can anyone provide, or guide me to, such a video?
