Page: 72 / 114

A CJM file’s contents look like this:
X:64,ntsc,accuratedisk,driveicon
J:1*:JU,JD,JL,JR,JF,JF,1,2,JF,A,B,C,JF,4,5
J:2:JU,JD,JL,JR,JF,JF,F1,F2,JF,1,2,3,JF,F3,F4
V:12
This first example sets the computer model to a C64 NTSC, enables accurate disk
mode, ensures that the drive icon is displayed in the top-right corner during disk
loading, defines joystick functions for both port 1 (the primary controller in this
example) and port 2. Finally, it also vertically shifts the screen up by 12 display lines
to reveal more of the bottom border area of the C64’s display.
X:vic,pal,fullheight,35k
J:1*:W,S,A,D,I,K,J,L,CT,1,2,3,,EN,4
The second example sets the computer to be a PAL VIC 20, using the full height of
the display and giving a total memory of 35 kB to the computer. It then defines the
behavior of the joystick in port 1, assigning various key presses to the directional stick
and the buttons.
