Actually, my largest work was 30 years ago or so with BBS'ng and making stupid games in Smart Basic.
However, I am now trying my hand at Homebrew and Assembly Language.
As I am studying others work and looking for examples with simple Hello World and what not I am really trying hard to follow.
Without proper examples I am running into road blocks such as.
Here is a snippet of Code to display a simple line of text and set the colors and for my understanding can someone direct me.
call $1f82 ;BIOS Fill_VRAM
I can include this with all the other support routines and get red text with a white background. I can change any of those colors in the pallet.
My issue is how do I change the border color?
Back in the smartbasic days it would be something like poke 27384 for border and 27386 for screen color.
I may have these numbers wrong but you get the idea.
Can someone fill in the blanks like how to change the border so I don't have to use a blank screen
What is the ld hl, $2000 and the ld de, 32
Or maybe it is because I am using mode_1
Any help to get started.
I have looked on all the popular websites and have all the manuals, even the ones that you can't read, on OS5 and OS7
I know everyone has already figured all of this out but what I really need is example code in asm and a list of jump tables with the registers and examples.
If I had to guess I would figure it to be a simple register that you add a color value or leave it zero for blank being as there is nothing to program, you can't add graphics to the border as far as I know.
