Here in this thread are the latest ROMs, organized, for easy finding.
Note for CX80 Trak-Balls:
Atari CX80 Trak-Balls work the same as the CX22 Trak-Balls. However, some retailers modified the CX80's to be compatible with the ST Mouse (Atari Mouse). If you have a CX80 then you will have to try both the Trak-Ball and Atari Mouse ROMs to see which one works with your Trak-Ball, or try the detection ROM. It is believed only a small number of Trak-Balls were modified.
Note for CX22 Trak-Balls:
An early version of this controller only works in joystick emulation mode and cannot be used with these ROMs unless modified. Check for the presence of the "joystick/trakball" switch on the bottom left side to ensure that you have the later compatible version and set it in "trakball" mode.
Wico Command Controller Trackballs:
These trackballs don't work with these ROMs as is. However, the Wico Trackball can be converted to use the CX80 (Atari Mouse) ROMs. See here for details.
