Have just managed to get a working console in 1.12 by:-

1) changing "testmode" to "true" in g3.ini
2) changing "DisplayOnScreen" to "true" in debug.ini
3) adding " _compiledImage" folder to data folder
4) adding "_Intern" folder inside new "_compiledImage" folder

To enter console mode, I use key on top left of keyboard directly under ESC…..this could differ depending on kb settings.

I gather you have already done steps 1,3 and 4. Maybe step 2 makes all the difference???
