Is it possible to create X-fix codes for Psone games?

[ps80]

Hi. There are guides on creating Y-fix codes for moving the screen up and down on Psone games but I'm trying to find an X-fix to move the screen to the right on my games. The game I most want to fix is Final Fantasy VIII as the screen is offset to the left and there is no inbuilt option to position the screen. I've found the PAL2NTSC and Y-fix codes

PAL2NTSC code 8005DA7C 0000

Y-fix 80049BA8 FFF8

But is it possible to create an X-fix like you can for PS2 games

Is there a way of searching like with Y-fix codes?

Y Fix Type 1
24900013 addiu s0, a0, $0013
24900010 addiu s0, a0, $0010 <-
8622000e lh v0, $000e(s1)
Pattern= 1300902410009024 Puts you one line above the code

Any info would be a help as I've found nothing by searching the web.

Thanks
