Re: 384 rows super HRG
Your screenshot seems not to match Stefano's. That is the differene of AI (artificial incompetence) versus reality :mrgreen: Well, yes. You are both right, I haven't considered the phase. I have no way to predict whether the TV display will be drawing the even or the odd lines series when the drive...

Re: 384 rows super HRG
I don't remember whether I placed the display buffer at 32768. It's a 12k blob, it overflows easily.

Re: 384 rows super HRG
I took a photo with my phone while the picture was being generated on EO.
Then I cut a portion of it, but the result is what I was hoping to get.
M1NOT shouldn't be necessary. In theory a 32K RAM expansion capable of wrx graphics should work.

Re: 384 rows super HRG
The idea was to show two different high resolution frames.
The second time the CRT beam should pass slightly shifted, between the previously displayed lines.
This could produce a 192x2 picture, slightly flickering with overlapped pixels

Re: 384 rows super HRG
Eighty One with the WRX graphics option enabled and 32k ram runs properly (with the advanced video effects enabled).
Obviously I'm pushing it to the limit, I wouldn't be surprised if the program crashes on a real zx81.

384 rows super HRG
Can anybody test this one ?
It should work in WRX mode with 32K ram.
You should see 2 lines, one will appear in standard resolution, the other one sould be more refined.
The resolution should be 256x384 interlaced.

Re: Enhanced ARX True High Resolution Display Driver
I've noticed that ARX graphics driver is still unstable when used in 64 rows mode if the break detection is excluded. I'm investigating. In attachment a bouncing balls demo in 64rows mode (runs much faster than on a full graphics page). The ARX version incorporates the BREAK detection as a workaroun...

Re: Enhanced ARX True High Resolution Display Driver
All, I've updated the libraries already in the Z88DK tree. On any problem I can get back to it and try to tune it better. The sampler archive I've posted some time ago is still very close to the current tuning, if something looks wrong please check the latest test cases before complaining. I can obv...

Re: Enhanced ARX True High Resolution Display Driver
The fractal program is cool but very slow. It probably takes some day to complete on a regular zx81, I'm tuning it to restrict the execution time a bit.
