Hello,
I'm using PC-Basic at school, to show pupils some examples of direct access to graphic memory.
I.e:
SCREEN 9 : DEF SEG=&HA000
POKE 0,255
Now, just to perform some more than a pixel toggling on screen, it would be nice to load a complete image.
Question is: does somebody knows which tools to use for this? I cant locate anything usefull on internet. May be because too many time is passed since EGA was the standard.
Not easy to do from scratch, because you have to manage separately 4 bitplanes, using only the EGA fixed palette...
So, do you know some tool to convert a generic image into a RAW EGA format?
Then I would able by myself to manually add the header bytes needed to BLOAD the image...
(ps: sorry for posting in the wrong section, now I cant move or delete this post!)
