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 |

Also, http://project64.c64.org/misc/map64.zip is very valuable to me whilst learning.
I made loads of notes, studied those sites I linked to, read and read various manuals and built up a better understanding of the memory map of the C64.
It's invaluable to put some effort into doing this stuff (thinking) yourself and realising WHY certain things are done in order to learn.
I'm still uber-noob, but I know that refraining from asking others to solve every single problem I face is the BEST way to learn! Your brain will thank you for it. |

Another coding über-noob here. This thread is a great help, all the essential hints and pieces of knowledge, explanations are here.
Although I have passed the part of understanding the way it works recently and hopefully I will be able to make my first simple one-file demo soon - I still appreciate the helpful attitude.
Respect for that, for all of you. That is the way the things should be.

Quote: or do it the other way round - align the code to the gfx.
This way you save quite some memory to be overwritten:
*=$5c00
hirescolmap
.bin 8002,1000,"gfxfun/rooms2.ip64h"
.dsb 24,0
hiresbitmap
.bin 2,8000,"gfxfun/rooms2.ip64h"
code_start
init_gfx
sei
lda #$06
sta $d020
lda #%00000010
sta $dd00
lda $d011
ora #%00111000 ;enable hires + screen on
sta $d011
lda #%01111000
sta $d018
PS: ip64h is interpaint HiRes - gimp with cbmplugs is able to export to this format ;-)
PPS: you could also put the code inside the 24 byte gap between bitmap and colormap but well....
Just what everyone else said x 1000. Thanks a lot to all. Just a quick question. I tried converting the quoted text acme but I don't know what .dsb is in Acme. Anyone know off the top of there head? |

Also, where do you get the cbm plugin for Gimp? I tried the CBM Plugin Registry with no luck. |

http://packages.debian.org/source/lenny/cbmplugs
and .dsb 24,0
means 24 bytes of value 0.
In this case to fill up the gap between 40x25 and 2^10.
Cheers,

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 |

@Stranger
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?
Thanks for All the Help,
