OK it is a very good news : the standalone version does work...
In fact, even if it seems quite strange it tends to prove it is a calibration issue (because in my standalone image the touchscreen driver is not the same than with navigation software > V8 and the manual calibration is required only with navcore > v8)
You should find the pointercal file on your internal memory in folder "tomplayer/conf"
If you have navcore v8.350 you should have a calibration process to follow the first time you launch tomplayer in order to create this "pointercal" file...
you are right :
files are not required : just text files with no functional use...
Again right : do not replace your ttsystem in internal memory by my ttsystem (unless you want to get rid of navcore and use your tomtom only with tomplayer
tell me if you find the pointercal file at last,
