8-bit acorn emulators • Re: Input lag of different emulators / implementations

Hi Thomas, is CLK available in BBC model B flavour, I seem to remember asking before, but think the only Acorn was the Elk.
Alas no, because I think it would just embarrass me; it has a 6845 that's used for machines including the Amstrad CPC and which is based on an FPGA implementation that I read but which still doesn't quite seem to act correctly.

So currently CLK does the Electron and an Archimedes only from Acorn world, with the differing articles doing some heavy lifting to paper over the fact that it aims for the platform, not a specific machine, i.e. that I'm handwaving away bus fidelity. Timers and the VIDC interact with proper fidelity, as does the floppy controller, but the CPU is accelerated without a concrete foundation in actual bus activity. On the plus side, that gives me leeway to let it run fast most of the time but automatically clock itself down if it realises there's a Lander-type runaway frame-rate situation.
