But, the VB81 XuR limitation on the ZX81's display routine had to be completed by EO to check this kind of codes.
Xavsnap What does this mean?
Vb81 XuR, was originally coded in Visual Basic, and we had to choose a short-cut to speed-up the display!
The orginal codes was based on the D_File mirroring ...
A PRINT"A" was intercept and display as a graphic character "A" in the D_File.
All ROM or customs routines are ignored!!!
for example, the Andy Rea's display routine won't work on Vb81XuR !
But, all graphic cards and UDG are using proper emulated device!
And most of IX instruction are redirected to get the true display.
If I understood the following:
ZXbasic pulls up the "older" bas2p.exe... So ZXtoken would be used instead.
Yes, ... or Vb81...
ZX Draw Does it have another replacement since I have not got it running?
Most of ZX81's tools are implanted in VB81!
Just select the "Tools" menu, and "EasyDraw!" window. (on a 16k expended D_File, before a SAVE command)
A jpg or bmp can aslo be digitalized in the "P_Tools" and "Digitalize a bitmap picture..."
You can save the actual screen in a basic file if you select the "*.BAS" attribute!
It will save it in the riched_ZX81 encoded characters code.
"P_Tools" , "D_File tools", "Save current D_File..." and type your "screen_name.BAS".
Vb81 XuR is a funny game, and many tools are hidden and (shift)[ctrl] can be used to find more facilities...
Example, in the "Disassembler" window, you can click on the header to get another read format...
Right click on an opp-code will set this "DATA" to text, "ASCII", "Data" or return to an "ASM mnemonic".
... To disassemble the code using right jump and better conversion to a text file ("save code >target format>tasm mnemonics text format")...
right click, ctrl key (alone), and right click on the last mnemonic to set a group to the right format!
