Hi my Konami Vendetta PCB has developed an audio issue. Music plays fine but sound effects are heavily distorted. I have done a Rom check and it is reporting a bad rom at 1D.

From what I have read this checks out right? 1D handles audio?
Any ideas how to fix this? I have never worked on a board before and the Rom isn't socketed so it is probably out of my league. Can this be easily replaced? I hear audio issues are common on these 4 player Konami boards.

Any help is welcome

Thanks.

Audio samples are stored in this device :

ROM_REGION( 0x100000, "k053260", 0 ) // samples
ROM_LOAD( "081a03", 0x000000, 0x100000, CRC(14b6baea) SHA1(fe15ee57f19f5acaad6c1642d51f390046a7468a) )

It's a 8Mbit MASK ROM so you can replace it with a programmed 27C800.If it turns out the MASK ROM is good then the problem is the Konami '053260' custom IC that plays the samples
