[Script] Need help fixing evolutions Fire Red

Hi there, I've messed around with ROMs previously but this is my first time editing scripts of any kind.
I added a heap of non-regional Pokemon but when I go to evolve them I instead get the message "...?"

I know that this is caused by not having the National Dex, so I found an old forum post that said to edit the 4 byes after 0xCE91A to 00 00 14 E0, which is meant to fix the evolutions. Now, however, I just get an infinite evolution screen where I can't press anything and I have to reset.

After that failed, i tried inserting a script to add give me the National Dex early, but I kept getting an error message about there being too few parameters on Line 9. The script was as follows:

#org 0x800000
lock
faceplayer
checkflag 0x10A
if 1 jump 0x800050
special 0x16F
setflag 0x10A
fanfare 0x13E
msgbox 0x800100
callstd 0x6
waitfanfare
release
end

#org 0x800050
msgbox 0x800070
callstd 0x6
release
end

#org 0x800070
= Like your new POK?DEX?

#org 0x800100
= Your POK?DEX was upgraded!

I'm also worried that by giving myself the National Dex early it will trigger Lorelei leaving for Four island early and hence locking me out of the E4.

Can anyone help me out? I'd like to Hex Edit to fix the evolutions but not sure exactly how to, and the script I tried to add didn't seem to work either.
