EGA 512x384 CRT Timings issue

[Jordan-Belfort-88]

I've been trying to find the correct timings using Modeline Studio but the best results I was able to get are the next timings:

Modeline "512x384@60Hz"
Frequency: 32.5
HVisibleArea: 512
HFrontPorch: 43
HSyncPulse: 68
HBackPorch: 9
VVisibleArea: 384
VFrontPorch: 22
VSyncPulse: 3
VBackPorch: 22
-HSync -VSync
DoubleScan
VisibleBegins

moveScreen (-11, 0);
shrinkScreen (-5, -15);

The issue is that the display is showing six smaller screens instead of one big 512x384 screen. I've tried thousands ways to configure the timings and can't get it done
