Re: Robotron Z1013: KRT Highres Graphics

I noticed an issue with the latest jkcemu: I couldn't get .tap program to autostart on the z9001, reverting to 0.9.7 restored the behaviour. The JKCEMU emulator issue with the non-autostarting Z9001 TAP files is a bug, the author will fix it for the next release. I've just noticed that some time ag...

Agreed, it was reproducing the problem exactly as on the original hardware!

Re: [SMS] Mono sprites snail trail problem

I agree, I was betting on the VDP transfers concurrently with you. :). Having a real hardware to test on is always of great help, though. Do you think we can do some trial and error with Robert? Sure, I am ready to do trial-and-error testing until we get it working. @SMS owners: search for "DI...

[SMS] Mono sprites snail trail problem

I am now able to test .sms files on real Master System hardware. In my game Deepspace, the spaceship leaves a snail trail behind it, similar to the one we had on the Agon light , only a bit more ragged. 2023-11-17_SMS_Deepspace.jpg Any idea what could be wrong here? In the Fusion emulator, everythin...

Re: (classic) New target; Agon Light

My tester has confirmed that the diagonal line is gone now, thanks. The snail trail is still present on his 1.03 Agon Light. He will update it to 1.04 once it has been released (he does not want to mess around with the RCs). The fact that the onboard VDP is different code to the emulated VDP is also...

Re: (New Target) TIM-011

Please elaborate: how do I take the boot tracks and the required CP/M boot files out of tim011pcw.img?

Maybe with the Samdisk tool mentioned on the CP/M platform page?

A step-by-step description would be nice to have, we could later add this to the CP/M platform wiki page.

Re: (New Target) TIM-011

Back to the TIM-011, here's a crazy idea: how about letting appmake create a bootable disc? That means, taking the machine-specific CP/M boot disc image and putting the binary file on it? CP/M has been made open source by Digital Research last year, but the hardware-specific part could be legally pr...

Re: (classic) New target; Agon Light

Here is a quick Excel hack with a macro-generated preview of the 16 Agon Light colours, and in the last column I have assigned the named colours that IMHO should make sense. P.S. What might be confusing to z88dk newcomers is that the "light" colour always stands for the "darker" ...

Thank you, the default colours in Mode 2 are perfect now, and in the other modes they are good. In modes other than 2, "Lightcyan" doesn't really match the current yellow colour. But I assume this was chosen because that yellow colour wasn't mapped yet. NamedColoursTest_AgonLight_Mode1_512...

Re: (classic) New target; Agon Light

With the latest release 0.4.0 of the emulator, a Windows-compiled binary is available for download.

The z88dk-created .bin files look good, almost everything seems to be working fine.

Only c_plot() and c_point() do not work yet, please take a look with my plottest.c program.

Here is a simple feature request for the ZX81 and ZX80 targets: could we get a command line parameter to disable the inverse printing of capital letters?

Re: (classic) New target: Triumph Adler/Royal Alphatronic PC

Very good, thank you! That makes Deepspace work on the Alphatronic. And the mono sprites perform very well.

Is there a way to get rid of the blinking cursor? You can see it in the 160x72 grtest in the top left corner.
