yes they are med res, *supposedly* there is a dip switch to change to standard res , i dont know if thats all blitz or just the ones that were in conversion kits.
There should also be a setting in the cmos(on screen adjustments) to pick either 49 way stivks or standard 8 way sticks.
PReferrably, youd want a med res monitor and 49 way stick to get full enjoyment out of the game, but what what you got, im sure you could still use this blitz kit and make it work... just keep in mind your guys wont move around quite as smootly as they would with the 49 way sticks and board.
you may want to find the manual, or better yet a conersion manual, that would answer all of your questions for sure.
