Re: Block save / load
If it is a problem of timeout waiting for a signal,
a trick maybe to wait for the signal in the "pre loading" setup part, and immediately jump to the loop as soon as the signal is detected!
(code size there do not count )

Re: Block save / load
With the deletions you've done I do not understand how you will stop loading (before in loading loop I've put the checking of hl against de) and how you start the loaded program (before I've put a jp after the load loop completed) PS: the stack should be set at 4400 (call and push will start decreas...

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 no clue on how to slightly shift the lines but the idea seems ...

Re: Block save / load
The loader routine is just 17 bytes ("_BEG" to "_END"), and it is relocated to the end of the memory at the program start. Everything else is rewritten as all the rest of the memory during the load process. And become even 16 bytes because the loader stop when it starts overwriting itself (for now j...

Re: Block save / load
I have at the moment no means to test it (my dev environment is broken), but the following program should be able to fully load 1008 bytes into memory (from 0x4000 to 0x4400 - 16 bytes)... The block to be load should be saved with standard routines and should be equal or bigger than 1008 bytes (if b...

Re: 384 rows super HRG
384 lines :o :o :o what type of sourcery are you trying to use?? I was thinking about the fact that since the ZX is "executing" the display and on a standard machine if I remember properly just 25% is left for the program execution, doubilng the "execution of the display" should not be possible sinc...

Re: Block save / load
... Advantages: 1. will load from 4000h instead of 4009h allowing to immediately fill this space with data 2. will allow immidiate utilization and filling of system variables needed by BASIC (program will start immediately the machine code) 3. will avoid the basic program skeleton to start the mach...
