I am unable to compile the official CHDK version 1.6.0 because I do not have the correct compiler.

I compiled and updated fork based on CHDK 1.6.0. Not everything can work as it should, I did not include DIGIC 6 processors. I will review the codes sent here. I have downloaded GCC 4.9.3 arm none eabi and compiled the project.

 ;) ... #5189 to download on demand:
https://app.assembla.com/spaces/chdk/subversion/source/HEAD/historical-branches/g5x

and a step more of what happened since adapted ...
                       :-X
Code: [Select]
games/gui_snake.c: In function 'game_over':
games/gui_snake.c:297:30: error: 'LANG_SNAKE_POINTS' undeclared (first use in this function)
gmake[1]: *** [.o/gui_snake.o] Error 1

Some success again, compiles fine for Sx230 & 280,... ( not for G5x, stuck in gui_screw... :-[ )

Waveform and Vectorscope on the new version are not working properly. I was based on the dimensions 360x240 and in the attachments I present the sequence on the viewport buffer. For performance reasons, data is taken every few pixels, i.e. only some rows and columns. I believe it is not the width in bytes but in pixels. I need to check it out more closely.

I haven't been following closely, but FWIW, in general, it's not safe to assume viewport buffers are always 360x240.
Don't forget what the H stands for.

Right, I should probably use
viewport_width = camera_screen.width
for the purpose of allocating the waveform buffer

So far I have used camera_screen.width for the waveform memory allocation instead of 360/3. Using vid_get_viewport_width_proper and vid_get_viewport_height_proper caused the system to crash in waveform_process and I don't know why. I gave up on registry variables because I think they are causing waveform to malfunction. Something shows up with Live Preview during Record mode when it shouldn't. It worked fine in Play mode. I have not noticed a significant improvement or degradation in performance because of this.

;) ... You could retry with pasting lines 125-237 from ../platform/G12/lib.c to the lib.c of Your cams.
Edit: // Default implementation of PTP live view functions is in ../platform/generic/wrappers.c, 1823~.

Edit2: Probably good for each approach...  :-[
Code: [Select]
    switch (histogram_stage)
    {
    case 0:
        ...
        //condition allocate memory
        if (histogram_allocated==0) histogram_alloc();

        for (c=0; c<5; ++c)
        ...
