There are so many threads about changing a word to another that I can't count them on my fingers and toes...It always come back to the same things:
You need to change the instances of "espers" in the C3 bank. Luckily for you, "fomors" has the same length than "espers".
Code:
C3/5C48: 0D7984ACA99EABAC00 (position of and word "Espers")
C3/5C51: 8D798C9AA0A29C00 (position of and word "Magic")
C3/5C59: 8D7A92B09D939E9CA100 (position of and word "SwdTech")
C3/5C63: 0D7B81A5A2ADB300 (position of and word "Blitz")
C3/5C6B: 8D7B8BA8AB9E00 (position of and word "Lore")
C3/5C72: 0D7C919AA09E00 (position of and word "Rage")
C3/5C79: 8D7C839AA79C9E00 (position of and word "Dance")
Code:
C3/5C87: B7818C8FC7FFFFFFFF00 (position of and word "MP... ")
C3/5C91: B7818BA8AB9E00 (position of and word "Lore")
C3/5C98: B781919AA09E00 (position of and word "Rage")
C3/5C9F: B781839AA79C9E00 (position of and word "Dance")
C3/5CA7: B78184ACA99EABAC00 (position of and word "Espers")
C3/5CB0: B78181A5A2ADB300 (position of and word "Blitz")
C3/5CB8: B78192B09D939E9CA100 (position of and word "SwdTech")
C3/5CC2: 2D428B9500 (position of and word "LV")
C3/5CC7: AD42878F00 (position of and word "HP")
C3/5CCA: 2D438C8F00 (position of and word "MP")
The same goes for GP, except you need to write "gold" elsewhere because "gold" has more letter than "GP" and there is no room for extra letters, like usual. Then you need to make the appropriate changes in the code to reflect where the new data is. This is where the words are for the menu and shop menu. There is some room at the end of C3 to write "Gold" if you want. Note that there is two instance of "GP" and one instance of "Gp".
Code:
C3/37CB: 397988AD9EA600 ("Item")
C3/37D2: B97992A4A2A5A5AC00 ("Skills")
C3/37DB: 397A84AAAEA2A900 ("Equip")
C3/37E3: B97A919EA5A29C00 ("Relic")
C3/37EB: 397B92AD9AADAEAC00 ("Status")
C3/37F4: B97B82A8A79FA2A000 ("Config")
C3/37FD: 397C929AAF9E00 ("Save")
C3/3804: BB7C93A2A69E00 ("Time")
C3/380B: FF7CC100 (":")
C3/380F: B77D92AD9EA9AC00 ("Steps")
C3/3817: 777E86A900 ("Gp")
C3/381C: BD7A989EAC00 ("Yes")
C3/3822: 3D7B8DA800 ("No")
C3/3827: 377993A1A2AC00 ("This")
C3/382E: B7799D9AAD9ABF00 ("data?")
C3/3836: 377984AB9AACA2A7A000 ("Erasing")
C3/3840: B7799D9AAD9AC500 ("data.")
C3/3848: 377A8EA49AB2BF00 ("Okay?")
C3/3850: 3D818EAB9D9EAB00 ("Order")
This is for the shop menu:
Code:
C3/C2FC: 0D79969E9AA9A8A700 ("Weapon")
C3/C305: 0F7980ABA6A8AB00 ("Armor")
C3/C30D: 0F7988AD9EA600 ("Item")
C3/C314: 0D79919EA5A29CAC00 ("Relics")
C3/C31D: 0D79959EA79DA8AB00 ("Vendor")
C3/C326: 0F7A819498FFFF92848B8BFFFF8497889300 ("BUY SELL EXIT")
C3/C338: 417A868F00 ("GP")
C3/C33D: 2B7B868F00 ("GP")
C3/C342: B37A8EB0A79E9DC100 ("Owned:")
C3/C34B: B37B84AAAEA2A9A99E9DC100 ("Equipped:")
C3/C357: 8F7B819AADFF8FB0AB00 ("Bat Pwr")
C3/C361: 8F7B839E9F9EA7AC9E00 ("Defense")
C3/C36B: A57BC700 ("…")
C3/C36F: 1F7987A2BEFF829AA7FF88FFA19EA5A9FFB2A8AEBF00 ("Hi! Can I help you?")
C3/C385: 1F79879EA5A9FFB2A8AEABAC9EA59FBE00 ("Help yourself!")
C3/C396: 1F7987A8B0FFA69AA7B2BF00 ("How many?")
C3/C3A2: 1F7996A19AAD9CA19AFFA0A8ADBF00 ("Watcha got?")
C3/C3B1: 1F7987A8B0FFA69AA7B2BF00 ("How many?")
C3/C3BF: 1F7981B29EBEFFFFFFFFFFFFFFFFFFFF00 ("Bye! ")
C3/C3CE: 1F7998A8AEFFA79E9E9DFFA6A8AB9EFF868FBE00 ("You need more GP!")
C3/C3E2: 1F7993A8A8FFA69AA7B2BEFFFFFFFFFFFFFF00 ("Too many! ")
C3/C3F5: 1F798EA79EC3ACFFA9A59EA7ADB2BEFF00 ("One's plenty! ")
This is where the word "GP" is called. You need to change the value of the LDY to the new offset in C3. If you write "Gold" at C3/FFF0 it will become LDY #$FFF0.
Code:
C3/3238: A01738 LDY #$3817
C3/323B: 20F902 JSR $02F9 (display "GP")
Code:
C3/B969: A038C3 LDY #$C338
C3/B96C: 20F902 JSR $02F9 (display "GP")
Code:
C3/BBC3: A03DC3 LDY #$C33D
C3/BBC6: 20F902 JSR $02F9 ("GP")
Code:
C3/B826: A0CEC3 LDY #$C3CE
C3/B829: 20F902 JSR $02F9 (display "You need more GP!")
I think this is all...
