Download a
.tbl file for FireRed,
Translhextion,
XSE 1.1.1 and
HxD because Translhextion's layout is awful.
Load your ROM in Translhextion, and then .tbl file in Translhextion (Ctrl + T). Check "Thingy View Active". Do the shortcut Alt + F and enter the text for Oak's speech, for example: "Hello, there!". Take note of the offset in Notepad or something (0x180388 in a vanilla FR ROM).
Close everything and then load your ROM in XSE. Create a script like this:
Code:
#dynamic 0x800000
#org @string1
= Hello world!
Of course, enter whichever string you wish.
Compile it and take note of the offset. Close XSE.
Take the first offset (0x180388) and convert it to a pointer, like so:
180388
[18][03][88]
[88][03][18]
[88][03][18] + [08]
88031808
Do this to the second offset as well.
Load your ROM in HxD. Do the shortcut Ctrl + R. In the first field, enter 88031808, and in the second, the pointer to your new string (if it was compiled at 0x800000, the pointer would be 00 00 80 08). Change "Text string" to "Hex values" and click "Replace all". Save your ROM.
Repeat this for all the strings you want to replace (I think there's about seven or eight in that intro.).
