I've had my vectrex for awhile but only just actually got a cart for it I got andrew coleman's 72in1 muti cart and as soon as I start playing it I noticed a few things I never did with minestorm first the names of games were really small and picture was not centred I've now fixed that by adjusting the pots on the inside and by using the test cart game but another thing is the flicker yes I know the vectrex can flicker sometimes when there's a lot of stuff on screen but is it me or does mine flicker more coz berzerk seems to ficker a bit until I kill all the enemies then its stops but games like spinball and vecter vaders and some others flicker so much its unplayable do these games flicker as much for you guys or is there another pot I can adjust on the inside to stop it a little ?
