[Script] [HMA] Pokeball Vanish and buffer pokemon starter [FR]

[sylinuser]

Hello,
I need help for editing choosing starter script in FireRed.
I want Rival take two pokeball.

using HMA, i already figure the offset position.

For movement script

Spoiler:

169D1F:
applymovement 8 <169D72>
{
walk_down
walk_right
walk_right
walk_right
walk_in_place_fastest_up
walk_down
walk_right
walk_right
walk up
walk_in_place_fastest_up
}
waitmovement 0

goto <169D2F>

with this, rival will move twice, once to first pokeball, then down for second pokeball

And the problem is the message box

Spoiler:

169D2F:
textcolor 0
loadpointer 0 <18DD34>
{
\\06: I'll take these two, then!
}
callstd 4
hidesprite 0x4004 ---->i guess this for pokeball
textcolor 3
bufferPokemon 0 0x4003 ---->this for starter pokemon
preparemsg <18DD52>
{
\\06 received the \\02\n ---->and other pokemon---
from PROF. OAK!
}
waitmsg
fanfare 318
waitfanfare
setvar 0x4055 3
checkflag 2110
if2 = <169D5C>
release
end

can anyone help me for

hidesprite 0x4004 ---->i guess this for pokeball

this only vanish the first pokeball (orignal),
how to make second pokeball vanish too?

bufferPokemon 0 0x4003 ---->this for starter pokemon

this is for Bulbasaur (0x4003), because i choose Squirtle.
i need to add Charmender too

{
\\06 received the \\02\n ---->and other pokemon---
from PROF. OAK!
}

So he will said
[rival] received the Bulbasaur and Charmander
from PROF.. OAK!
Thank you for the help 🙏
