Sure, I should have some time tomorrow to help out, for now I have to get to bed. But basically, it boils down to setting the 36869 register properly.

are you about?

You're using 7168 (and up) for two different things. Relocate either your character set or your screen memory.

this program makes the screen bigger. https://techtinkering.com/articles/changing-screen-dimensions-on-the-commodore-vic-20/ 10 rem demonstrate a 27x33 screen 20 rem lawrence woodman, nov 2019 30 print "{clr}" 100 rem lower top of basic to $1c00 110 poke 55,0:poke 56,28:poke 51,0:poke 52,2...

done it! i just re defined the character as 010101,etc and then used the correct code. it was 19 for an 's' ? weird....

no, doesnt work unfortunately. i tried 62 which comes out as purple (getting better). maybe i have to define a new character using 01,01,etc?

.......just tried that and im still getting garbage. no black...

thanks for all your help btw...

ok, so what number do i use? ive tried 0-255 and none of them are black, i dont think

ok, so i got it working by deleting line 110. the problem now is that the sprite clears a green line down the screen.
i guess i may have to use a black box sprite to do this?

OK, I see. So, yes, every time you run your program, the loop at line 110 will reset the whole character set back to the ROM characters. That's where the custom > character is being set back to its ROM counterpart. The code at 1000 is not executed during a RUN of this code, which may be at least on...

1000, goto 1000.


sorry, add this line.


20 data 255,255,255,255,255,255,255,255

the '>' characters should be blocks but they just disappear back to '>' s

that wouldnt give me black with my setup. my border color (black) is the desired background color
