The Clock Signal Emulator (“CLK”) has been updated. The CLK emulator for Mac OS and curated by Thomas Harte includes clock accurate emulation for a number of retro computing platforms. The latest version of CLK includes the following changes:
adds support for the Oric vsync hardware hack, and also corrects the Oric’s 60Hz frame length better to support software vsync; and
improves — but far from perfects — its 6845 emulation, as primarily surfaced in the Amstrad CPC.
