Exomizer comes with a manual on how to compress data. However there may be people who are quite new to using the Exomizer tool, and the decruncher source, provided with Exomizer. I find Exomizer to be VERY useful for level packing single or multiload files. Some times decrunching binary/source data can be a right pain in the neck. It is also very flexible with decrunching memory.
Depending on the path used the command used (for example compressing a koala paint picture) is :
exomizer mem -l $2000 mypic.prg,$6000 -o mypackedpic.prg
This will load a koalapaint picture to $6000, then pack the memory to $2000. Exomizer then displays the pack result at the end of the crunching phase. If not using a crossassembler You must note down the END address in which the pack address lies. However if you are using a cross assembler, then you don't need to note the memory. Since you can use labels to indicate the end of the current load address.
An example program (in ACME/C64Studio):
!to "koalapaintdisplayer.prg",cbm *=$1000 sei ldx #<PicDepackEndAddress ldy #>PicDepackEndAddress stx $c010 ;Exomizer depack address low sty $c011 ;Exomizer depack address hi jsr $c000 ;Exomizer decrunch source ;Rest of pic display code.... ... Type in your own pic display code *=$2000 PicDepackStartAddress !binary "mypackedpic.prg",,2 PicDepackEndAddress
