I am currently developing a game in assembly, and have a serious problem - TASM won't let me draw a pixel on the down-right corner of the window (being 39X24, since i'm using mode 13h\4h). Whenever a pixel is about to be drawn at that spot, the window scrolls down and doesn't draw the pixel anywhere at all.
The problem is not related to the graphic mode I use, as I tried several others with no success. It also have nothing to do with anything included in the game itself, because even when I tried to draw a single pixel there, unrelated to the game, the window still scrolled down.
This is my code for putting the pixel on the screen:
Code:
mov dL, 39
mov dh, 24
xor bx, bx
mov ah, 2
int 10h
mov dl,254
mov ah, 2
int 21h
Does anyone knows what could be wrong?
