mega drive model 1 and 32x RGB problems

[flax]

I bought a 32x without the hookups (i know, bad idea, but it was cheep) and im trying to make my own coords.

Cant get them to work properly though.

When i try to play Doom32, the menus are fine, but the game itself is out of sync.

Overall the screen is a bit to red and dark.

The screen flickers a bit, black horisontal lines, not much though, but every now and then theres some lines here and there.

Original 16bits games works fine, except the lines and the red thing.

I've buzzed the cords with a multimeter and everything seems fine.

this is how ive hooked everything up:

The flickering and color problem are caused by some bad joints i suppose. but ill tackle that when i get the sync problem fixxed.

Any ideas?

says there should be some caps on the RGB lines, but that shouldnt have anything to do with the sync problem right?
