Disabling (quadsemi) on PSX

Ok so I have this game (castlevania chronicles)

Anyway I am trying to make a map of the whole game.
I have manually edited out HUD items from the game graphics.
However the HUD semi transparent texture remains.
I loaded up the game and found the area that I believe is the culprit
Take a look:

Anyone have a clue what steps I need to do to disable it ?
I am guessing making a gameshark code would work.
When I select this area in no$psx I get:
CPU.PC:    80044574

DMA.Start: 0005A804
DMA.Link:  000F3038

I don't really know where to go from here any clues would be helpful.
