Thanks, this version works better than your first which has a little artifacts here and there. I also patched one myself following EMlyDinEsh's guide which is similar to this one but different by 1 digit, which also works so far with no visible signs of artifacts. Will try connecting both VGA and HDMI and see how it goes.
Update: Having both VGA and HDMI monitor connected causes some weird artifact effects. It picks up both monitors but they are mirrored. When I disconnect one of them, the artifacts begin and system starts to hang. If connected to one or the other, it seems to be pretty stable.
