Re: Enhanced ARX True High Resolution Display Driver
Thank you. Could you test both the programs? They seem identical but one of the two includes a break keys detection

Re: Enhanced ARX True High Resolution Display Driver
Yet another prototype. Am I getting closer?

Re: Enhanced ARX True High Resolution Display Driver
Ok, I'm trying to merge in the Paul's code, but honestly I'm doing it mechanically, replacing the existing code portions with the new ones. I haven't identified the code changes permitting the better control of the picture sync, and the 64 rows mode is temporairly lost (on my prototype) but it is so...

Re: Enhanced ARX True High Resolution Display Driver
I see. I will try to merge your code, but as you probably saw the z88dk driver is rather different.

Re: Enhanced ARX True High Resolution Display Driver
Some more sample programs
Some of them required a manual build of lib3d.lib altered with the -IXIY trick, yet another todo for the z88dk project

Re: Enhanced ARX True High Resolution Display Driver
The resulting programs after my crappy fix: could anybody see if it fixes the problem ? I could have introduced the problem trying to reduce the code size (e.g. heavily relying on ROM calls) because changing the way to test the BREAK condition is apparently enough to solve the problem. The code size...

Re: Enhanced ARX True High Resolution Display Driver
Hello, I remember that behaviour, I never understood it was appearing because of the ZXpand interface! I was finally able to reproduce the problem, I'm inserting a simple fix which solves on EO. The current driver code is here, it is quite different from the original one because it includes video ef...

Re: How to run .TRD spectrum files ?
The TRD format is a pure sequential, sorted dump of the disk sectors. The formatting is guessed by the emulator depending on the file size.
I suggest to try with SAMDISK, it is usually able to convert to other disk dump formats by adding the needed extra detail.

Dallas game port (32K)
There's surely space for improvements, like a colour version of the game or trying to exclude the initial banner and compress the maths by using the ROM. By the way here's a first, mostly untested version of the DALLAS game for the Lambda with 32K RAM, in the three ROM flavors (V1, V2, and CAC3/NF30...
