Fatal fury 3 plays blind , metal slug x no response

Recently got two mvs carts off the bay, to try and fix them up. Fatal fury 3 boots up and you can hear the game intro and everything. no neo Geo logo at start up, it shows the winners don't use drugs and then goes black again. Tried reflowing everything but no luck. What's the video chip on these things? Next step? I definitely want to learn how to fix carts



Metal slug x just goes to crosshatch. I examined this one and it looks mint. Right when I was goona give up I remember reading somewhere that if you see a bump or hump in a chip then it's gone bad and that's exactly what I found. The light on the bottom chip there sort of shows the hump in the chip, best way I could get a pic of it

From Neo-Geo.com
"Your going to need to examine your PROgram board . Examine your P-1 chip.......Does it have a bulge protruding from the center of it? If so,it's fried.You may have to examine under well lit area to notice.

With your Metal Slug X cart - it's entirely possible it's not faulty. Are other carts still working on the same MVS board? Have you run the board test to make sure there's no faults? Have you cleaned the pins on both the motherboard and the cart to check and see if it's not getting a good connection?

If you have - try inserting the Metal Slug X cart more gently, I've found I get all kinds of issues (mostly crosshatch) if the cart is inserted too far.

Let me know where you get and we'll go from there.

First and only game to not work , minus the fatal fury 3(got them together as not working)
I've cleaned the pins on the cart and on the board. I'll try putting it gently
 
Nothing from metal x , presumed dead because of that bubbled toshiba chip(p1). What's the option for replacement? Can anyone burn me a replacement p1 chip for metal slug x if no originals available ? Just tell me how much!

Tried fatal fury 3 again and coined up and entered a fight and this came up on the screen. Assuming the squares are the faces of the characters , there are also green bars which I'm assuming are for names and health also (can't see in the picture , it was very faint )
What chip(s) on the two boards should I be addressing regarding video output?
