CPS1 graphics error

[MegaMan]

Hi, I know someone who is selling this MegaMan the power Battle board and Im not sure what’s wrong with it or how to fix it. There are lines going horizontal across the screen and there is no background. The audio seems to be good but I’m new to arcades and am not sure where the problem is in the board or how to fix it. Thanks for any help you can give me. I’ve added some pictures of the board and it playing on a monitor.

Part of the problem could be the chunk missing off the corner of the C board custom. And/or whatever forceful impact caused that damage likely caused other damage

But, as with every other thread on here asking about graphical problems, the most likely culprits are one or all of the following: faulty C board custom (seen in pic), faulty A board custom, faulty mask roms.

Yep, very likely it’s the damaged B21 on the C board pictured. Fortunately the B21 is the most common C board to find a replacement for.

C board faulty ! B-21 one ! it's a new method who can replace that C board model with the one released by @undamned ! Look on his youtube videos for the refferences ! I was thinking on this solution but ive obtained another 92631C-6 to put on my Daimakaimura . You can use a modified "92641C-1" sold by @sheep_nova with the Undamned's Infinikey CPS1 release !

So do you think it’s worth buying? If so how much is it worth? I want to fix it, I would hate to see a somewhat rare game get trashed.

See if the seller have another CPS1 stuff for sale and if he have , maybe there is one with similar C board (92631C-6) . Ask him to replace in the Megaman game and to see if working ! this way you can know certain if is worth

It's all about price. See if the dude will take $50 and then you have plenty of wiggle room to mess with solutions.
