FWT no longer crashes when going to play with patch V5. Neither in single nor in continuous mode.
In continuous mode I still get one JPEG image too few (as described before).
Liveview in CHDKPTP works but shows a split screen with two times the same image where the lower image flickers every second or so and becomes garbled for the fraction of a second. (screenshot)
UI overlay works and palette is fine.
When I use the camera to set things up the changes get reflected in CHDKPTP.
The Funct, up, down, left, right buttons in CHDKPTP cannot be used to control the camera yet.
