Ha, that makes much more sense, yay .
KUAL running successfully on a KT2 is a nice surprise .

As for eips, try to run this

eips_print_bottom_centered "Is the white edge to edge" 1

And see if the white background extends to the right edge of the screen. If it does, great, if it doesn't, see if tweaking SCREEN_X_RES to 608 for the KT2 case fixes it.

Thanks .
