[SNES] [Code Request] Lufia & the Fortress of Doom / Lufia II

[CATS]

Hi, and sorry for bothering you guys! I was wondering If it could be possible to make a game genie code that disables the text sounds (the ones that play when a NPC is "speaking" and the text appears in the dialog box) in Lufia II (SNES) and Lufia & The Fortress of Doom (SNES). My attempts at trying to learn how to make codes... kinda failed miserably. xD

Thanks in advance for the help!
