z88dk fixed
Posted: Thu Apr 17, 2025 7:37 pm
Few years ago we had a major rearrangement of the z88dk project directory.
It had the immediate benefit of including a good portion of the newlib into the classic library, plus a transparent switch between the sccz80 and the sdcc compiler engines and other similar goodies.
Dominic took also the opportunity to sort out the huge quantity of redundant code I had put in the libraries, leaving just a bit of testing and code debris to link properly. I could help with the graphics but the console code was so much improved that I had to study it first.
I admit I took too long, Finally, the zx81 console is fully sorted, if you had problems with the 64 or 128 lines mode, it's time to check it out again.
I put in also a funny mid resolution text option for the udg pseudo graphics mode, ideas and comments are welcome
EDIT:
Nope, there is still something broken, I think in the numeric output routines, but it could be elsewhere in the library: the touchy IX and IY registers are not fully preserved, I think.
