I'm having trouble recompiling sysd due to dependencies right now, but the attached program is a quick and dirty solution. Once I can get sysd built you'll be able to set a value in dr.ini for portrait to always be 'normal' or 'flipped'
- From the normal portrait orientation run "Flip Screen"
- To get back to "normal" rotate the screen twice from the menu
- Don't run "Flip Screen" if in landscape mode, it won't properly alert programs to redraw
- If something goes wrong just reboot (slide power switch over and hold for 5 seconds)
