Hey Guys, I have the MK2 Challenger hack board. I am getting these weird lines coming in the background.Do the roms need to be replaced? Who sells these?
what is this, or what would I need to do to fix this?
Any good leads to help me repair this would help..

note: take a look at Mileena she has a garbled face..

Also the lines I was mentioning are the yellow lines all through the game..

There's a surface mount chip in the middle of the board. Do the symptoms change when you tap on it or push down on it? If so, it'll need resoldering.

It's a custom DMA (Direct Memory Access) chip.

when you find the rom that's acting up pull it and use super fine grit sand paper on it and clean up the fingers/pins. don't sand a ton just enough to make it shiny again.

or you could do all of them (one at a time), make sure if you pull them you put them back in the right way.

tho most of the time the easiest fix is just pressing on them.
 
It is the single board...
I hope it only needs to be cleaned and reseated.
I'll keep ya updated..
I may as do em all if I'm going to pull the beast away from the wall.
What do you guys think of wheels on the bottom of the cab?
Anywho thanks I'll do that ...
 
It's the challenger hack board.. The sound is on board..
I hope the rooms aret soldered in.. I would hate to pull em and break the solder..
Yikes !!
