[Script✓] How to check does a specific Pokemon in the party have a nickname?

[STikER]

Okay, I found few posts saying that it is possible in FireRed by using special 0x7B, which is used in the Name Rater script. So, I found the analogous special in Emerald (special 0x7E). Then, I tested both of them and they DO NOT check if Pokemon has a nickname or not. They just check if a new given nickname is the same to the old one or not. So, does anyone know how to do it?

You can do this in a bit of a roundabout way. It isn't pretty, but it works. This is for FR:

Spoiler:

#dynamic 0x800000

#org @start
special 0x9F // Choose the Pokemon whose nickname you want to check, result stored in 0x8004
special 0x7C // Puts the chosen Pokemon's nickname in buffer 0x0
special2 0x8000 0xFF // Puts the chosen Pokemon's species ID in 0x8000
bufferpokemon 0x1 0x8000 // Loads the the species name of the species ID in 0x8000 into buffer 0x1
comparefarbytes 0x2021CD0 0x2021CF0 // Long list of checks, comparing each sequential byte of buffers 0x0 and 0x1
if 0x5 goto @Different // If any of the checked bytes aren't equal, the party Pokemon has a different name to its species name
comparefarbytes 0x2021CD1 0x2021CF1
if 0x5 goto @Different
comparefarbytes 0x2021CD2 0x2021CF2
if 0x5 goto @Different
comparefarbytes 0x2021CD3 0x2021CF3
if 0x5 goto @Different
comparefarbytes 0x2021CD4 0x2021CF4
if 0x5 goto @Different
comparefarbytes 0x2021CD5 0x2021CF5
if 0x5 goto @Different
comparefarbytes 0x2021CD6 0x2021CF6
if 0x5 goto @Different
comparefarbytes 0x2021CD7 0x2021CF7
if 0x5 goto @Different
comparefarbytes 0x2021CD8 0x2021CF8
if 0x5 goto @Different
comparefarbytes 0x2021CD9 0x2021CF9
if 0x5 goto @Different
msgbox @SameName 0x2
end

#org @Different
msgbox @DifferentName 0x2
end

#org @SameName
= Same

#org @DifferentName
= Different

Initially I tried to use comparebanks command but it always gave a false reading when comparing banks 0x0/ 0x1 and crashed the script whenever I tried to use bank 0x2. That's why it looks really ugly with all of the comparefarbyte commands ;_;

You can use a similar script for Emerald. Just change special 0x9F to 0xA2 (plus a waitstate), special 0x7C to 0x7F and special 0xFF to 0x149. The starting pointers to buffers 0x0 and 0x1 are 0x2021CC4 and 0x2021DC4 respectively - Just add one to each iteration until you've gone through all of the comparefarbyte commands.

You're such a savior! Thank you very much! It works perfectly! ^__^
