* edit to add 360 between the other modelines such as 192, 200, 360, 440, 576
That step is wrong. Those numbers are not "modelines". Remind the format:
crt_range 0-9   HfreqMin-HfreqMax, VfreqMin-VfreqMax, HFrontPorch, HSyncPulse, HBackPorch, VfrontPorch, VSyncPulse, VBackPorch, HSyncPol, VSyncPol, 
ProgressiveLinesMin, ProgressiveLinesMax, InterlacedLinesMin, InterlacedLinesMaxIn order to allow 360i, edit the range this way.
Default (allowed interlaced range 448i-576i):
crt_range0  15625-16200, 49.50-65.00, 2.000, 4.700, 8.000, 0.064, 0.192, 1.024, 0, 0, 192, 288, 
448, 576
Modified (allowed interlaced range 360i-576i):
crt_range0  15625-16200, 49.50-65.00, 2.000, 4.700, 8.000, 0.064, 0.192, 1.024, 0, 0, 192, 288, 
360, 576
