Cassidy Nolen Posted June 3, 2003 Share Posted June 3, 2003 First of all, I would like to thank everyone for help on my last question. I am now up and (mostly) running with things so far. My trouble is with the sample kernel that we are supposed to test. When I copy it into a notepad file, save it as a .asm file, run dasm, and then put it in my Z26 to test, the screen is 80% right, with a column of wierd stuff one in from the left (imagine if you will, splitting the screen into 5 even colums starting from left to right, my second column in is "inverted"; the colors start dark and go light the other direction. I have not been able to get a screenshot of it. I will try on my work computer tomorrow, this was on my home computer). Just wondering what I should be looking for, as far as casuse. Thanks to all, Cassdiy Link to comment Share on other sites More sharing options...

Thanks to all, Cassdiy This sounds like it's working correctly. The section of code I posted in the "help! sesson 8" request was the latest section of code at that stage, and we were playing with timing of things mid-scanline. If you replace the 'picture' part of the code with the following, you should have a 'clean' display... ; 192 scanlines of picture... ldx #0 Picture inx stx COLUBK sta WSYNC cpx #192 bne Picture Cheers A Link to comment Share on other sites More sharing options...

wapchimp Posted June 4, 2003 Share Posted June 4, 2003 when I drop the kernel;.bin or test.bin file onto Z26, it loads, but only shows a black screen - the file assembles ok - I am I right in thinking the file will not be written if the code is incorrect???

No, it will be written, but only partially. How large exactly is your file? It should have 2048 or 4096 Bytes. Link to comment Share on other sites More sharing options...
wapchimp Posted June 4, 2003 Share Posted June 4, 2003 they are all 0-kb - looks like i'm good at programming black screen shots - I didn't think it worked as dasm says DASM V2.20.05, Macro Assembler ©1988-2003 START OF PASS: 1 warning: Unable to open 'kernel.asm' then a table appears & it says complete & an empty .bin file is created.
