Assembly and adding a Picture

Hi All,

I have some assembly code written for ACME assembler. I was just curious how I would add a picture into the code. I got the pause down but I just need a picture to show. Doesn't matter what format. I assume I can change my picture to most formats specified.

This would be great if someone could let me know.

Thanks,
MisterMSK

Strager: PERFECT !

I've reading and trying several routines for displaying koala images (exported from Proyect One) and this the one that have worked like a charm to me. The explanation is also very clear.

Thanks, thanks a lot.

I remember back in the day working out how to do this without any documentation on the file format.
The bitmap portion of the file is 40*25*8 bytes, the colour information is another 40*25*2 bytes. The trick was to use the editor to change one thing, save the file, compare the binary difference. Rinse and repeat until it is understood where the different data is.

Or you can rip the code from Koala Painter :D

You are great. That works. I can't believe it. I got one final problem. After displaying an image I want to go back to a BASIC TEXT Video mode. I removed the last JMP and I inserted a 3 second pause. I change to the charater set to 21, as well as 23, but I still get the below image. How do you transfer back?
