I'm creating a game for msx2+ and I would like to split the screen in two. The upper part is fixed and the lower part is mobile via scroll. Do you know where I can find splitscreen examples? A thousand thanks
First of all I would like to know how you are developing the game. To create a split screen you have to work in assembly or at least in C because reaction times of less than 50th of a second are needed
Hi Daniele, if you want I can share the sources of the utility that we use in Tetris 2 Special Edition (t2se for short) to write the vdp registers to certain lines during refresh, it's a bit to understand/interpret.
HI
Marco
However, if you are able to program in assembly here you will find the procedures for working with line interrupts and creating any type of split you need:

Hi, thanks for the reply, yes I know assembly language quite well. I had already found that link but I couldn't apply what it said. Basically I would like to work in Screen 4, the first 2 lines above fixed and for the rest of the screen the possibility of scrolling. For now I have succeeded with a software scroll, so scrolling 8 pixels at a time, but I would like to do it hardware, both horizontally and vertically, so I can scroll 1 pixel at a time. I will try to re-read the information at the link you gave me better. Thanks again
