Re: Clock Signal: back again for the Mac and UNIX-ishes
Minor update; in full-screen mode it was previously possible to end up with a load of accumulated ugliness on the right-hand side of the display after loading. This is now fixed. The new release is where it always is.

Re: Clock Signal: back again for the Mac and UNIX-ishes
That appears to be a 60Hz program? So it rolls a lot . Screenshot attached. I see this discussion of adapting it to 50Hz; I'm just squeezing this test into a quick ten minutes before work so don't immediately have time for poking around but will try to see whether any solutions are available there. ...

Re: Clock Signal: back again for the Mac and UNIX-ishes
More fixes! Available now ! my .p validation was proven too strict by Humpty Dumpty, so has been relaxed; I've switched back to using one byte per pixel in the intermediate graphics buffer, at the cost of greater upload costs but so as to correct precision errors visible on some GPUs where the absol...

Re: Clock Signal: back again for the Mac and UNIX-ishes
Quick update to announce that the (hopefully) fixed version has now been released. So that's available for download here.

Re: Clock Signal: back again for the Mac and UNIX-ishes
I think I'm fine on hsync, I just had the three-bit graphics-indexing line counter reset awry. I guess time will tell whether I'm actually fine and/or whether my line counter is still off. I have hsync as the forums suggest: on the ZX81 only, incrementing with the CPU clock, wrapping at 207, being r...

Re: Clock Signal: back again for the Mac and UNIX-ishes
Okay, so what I had implemented was the Martin Korth version of the world: exiting vsync resets the counter. I switched to resetting the counter on any port output that occurs while NMIs are disabled. That seems to fix my testing set, though I worry a little about comprehensiveness. So, from: Before...

Re: Clock Signal: back again for the Mac and UNIX-ishes
It looks like something I'm doing in BiggOil upsets Clock Signal. Let me know if there's anything you would like from me if you choose to investigate. C I'll look into as soon as I get a chance; I'm fairly deep in Apple II emulation right now but I'm sure that'll all be tied up in the near future. ...

Re: ZEsarUX 6.1 BETA March 2018
Raising the bar, as always! Very, very, very minor observation, prompting the post: the old sourceforge address is still in your signature. That's really my only relevant observation. Completely off-topic observation: your documentation of the Spectrum Next opcodes specifies mul as D*E -> DE (i.e. 8...

Re: Copyrights for New Generation Software games (e.g. 3D Monster Maze)
This might be the worst advice ever, but: you could always just publish it and see what happens. Almost eight years ago, we at the company I was then at released a ZX Spectrum emulator for the iPad. I sought out every freeware or free-for-distribution title that I could find. If you check WoS you'll...

Re: Clock Signal: back again for the Mac and UNIX-ishes
Quick minor update: as I thought I would quickly be able to do, I've added ZON X support to the emulated ZX81. Binaries and source code available as usual . It should be cycle perfect, actually internally generating an audio wave at 1.625Mhz and then resampling it. So I'm optimistic of no aliasing o...
