Points and comments are a snapshot, not live.

A browser-based collection of tiny 8-bit emulators with cycle-stepped CPUs.

The page lists dozens of emulated retro computers, including the Amstrad CPC, ZX Spectrum, Commodore VIC-20/C64, Acorn Atom, and various Robotron machines. It also runs demos and games from pouet.net and csdb.dk, such as Wolfenstrad, Dawnfall, and Space Invaders. The emulators use pin-level simulation and cycle-stepped CPUs, where the CPU is ticked alongside other chips rather than acting as the controller.

What commenters are saying

The top comment praises the pin-level emulation model. The author (floooh) notes the page is outdated and links to the current version at floooh.github.io/tiny8bit/, explaining that the CPUs are cycle-stepped and the CRTC is not removed in that mode. Two camps: those impressed by the technical detail versus those annoyed by loud default volume. A user asks about the missing chips directory and is pointed to the chips and chips-test repos.
