It is my great pleasure to announce that the official ZX Spectrum Next distribution now includes CAVE81, my remake for the Sinclair ZX81 of CHIP-8 CAVE game, along with such great piece of software as 3D Monster Maze!
ZX81 compatibility will be achieved on the Spectrum Next thanks to Paul Farrow’s excellent emulator ROMs.

You can grab the latest ZX Spectrum Next distro from the official repository: https://www.specnext.com/latestdistro/

Enjoy!
