Re: Enhanced ARX True High Resolution Display Driver
More about the gray library, I have 3 possibilities,: the current driver shows a first frame 2 times, a second one only for 1 time. This is in theory correct because the picture would allow a higher persistence to one of the two allowing a dark gray and a light gray. By the way the 2 frames in a ras...

Re: Enhanced ARX True High Resolution Display Driver
Right, this makes a difference ..both?
..in the meantime I found a way to work this out:
I'm afraid it won't be healthy for your eyes !
I've already put the latest driver version online, I think it is already better than the previous ones.

Re: Enhanced ARX True High Resolution Display Driver
Updated timing values, they look correct on EO. I'm also adding a new feature, at a very beta release level to deal with an intelaced picture, the artifacts are espected (see picture) and in this moment it gets useful to see black areas (compared to gray). Could anybody see how it looks on the real ...

Re: Enhanced ARX True High Resolution Display Driver
While testing the new code on EO I noticed it could not work properly on 60hz sets. I don't remember how the old one was behaving, though.

Re: Enhanced ARX True High Resolution Display Driver
I posted a "sampler" one page ago (actually it is in page #3). It includes 64rows and 8K stuff (arx64*.p).

Re: Enhanced ARX True High Resolution Display Driver
It is good news, I suppose ? I will leave the NOP in though, so it won't stumble when run on EightyOne. I'm now trying to find a way to interlace two 64 pictures and get 4 grayscale levels (probably acceptable only on phosfor monitors, if I ever make it work). It should exist already in WRX mode. Wo...

Re: Enhanced ARX True High Resolution Display Driver
This is DSTAR without NOPs added. dstar_crashing_on_zxpandplus.p.gz I think in my original driver I've put an even longer delay block, by the way here's the current fix wit a single NOP I'm using in the updated driver. dstar_extra_nop.p.gz They are built with the "BREAK" feature, it means that if yo...

Re: Enhanced ARX True High Resolution Display Driver
The ROM entries I'm using at the moment: $29B - Other drivers use $29E only. Save blank lines, start NMI, POP registers and RETURN $29E - Update A', start NMI, POP registers and return to BASIC/programs $220 - PUSH register, then do VSYNC and get KEYBD $2A2 - Enable the NMI generator and return to t...

Re: Enhanced ARX True High Resolution Display Driver
Well, if the picture is showing correctly in both the cases, we are going in the right direction. The sampler includes something running in 64 rows mode. I noticed that for some reason the interrupt timer runs twice faster which could mean the driver is refreshing at doubled rate when in 64 rows mod...

Re: Enhanced ARX True High Resolution Display Driver
the wrx driver relies on ROM routines, it could be that something is different on the improved ROM. @Paul, I will provide a build with and without the NOP. Oddly it was only DSTAR crashing, and only in full screen mode. The BREAK feature is rather subtle, you probably can't experiment it on the exam...
