I never looked for it.

If all those conditions are false, the program will start executing code here later on like you'll see in that tutorial (you really MUST know what asm commands do and have "programming understanding" to be able to follow the code here (and continue further on to make those trainer groups have their own battle music).

445D3
ld a,[$D042]
and a
jr nz,+$A ; if link battle(?), go to 445E3
ld a,$24
ld hl,$694E
rst $8
ld a,e
and a
jr nz,+$5 ; if in Kanto, go to 445E3
ld de,$002A
jr +$3 ; we’re done

; 445E3
ld de,$0007

Those values loaded in register pair de determine the battle music played when you face a trainer in Johto (2A) and Kanto (07). You'd have to add additional checks for Scientist and Rocket (Executive) trainer groups to have a new battle music for them.

Study assembly, that's all I can say to this.

Maybe, that'll only change the pallet in TLP

Forgot this!

Btw, can I'am add new trade person?
ex: in original there are 6 person who trade pokemon to us, so add new one person in the game and trade with other pokémon.
Anyone know how to that ?

It doesn’t involve assembly at all. Just add a trade to the trades data structure and use the trade script command (see Tauwasser’s doc).

You do have to follow the routine to find where trade data is stored in ram and repoint it elsewhere before doing this though. I may be wrong but I believe all 8 bits of the byte in ram used for storing trade data are already used.

I noticed I had written it down; trade "flags" are stored in ram address $D685. If something else is written in $D686, you shouldn't add any more persons to trade with unless you repoint the trade flags elsewhere in ram first.

The sprite they use has to be in that map's spritesheet (also editable by Johtomap). If you try to make someone use a sprite that isn't loaded on that map, they will look like Hiro instead. You also can't just add a new sprite to the end of a spritesheet, you have to replace one that is already in there.

On inside maps, however, you can pretty much use whatever sprite you want. Inside maps don't bother with the spritesheet, they just load the ones that are used on that map when you enter. So it might be easier and cause less potential problems if you made your Mr. Mime be inside the route gate instead of in Azalea Town.

Because there is only so much space in VRAM for it to load sprites. Some maps (olivine city, the route with sudowoodo, etc) use the variable sprite slots so the map can load different sprites at different times, but that still has its own limitations as well.

I would take a look at Miksy91's town map tutorial and see if that can be of any help to you. Honestly, I've never had a bug like that to know from experience what would cause it or how to fix it, but I'm guessing that somehow the flight table is messed up, or the towns have the wrong location byte or something. I can't really test anything right now, I'm in class and only have my phone on me. But look through the town map tutorial and see if you can figure anything out, and let us know f that fixes it or not.

It's no problem, after all it was me who decided to come to the forum during class. But hopefully that tutorial will help you out regardless.

The graphics themselves start at 0x8EABE

My Pokemon editor can change which one of these sprites a Pokemon uses in the menu, but if that doesn't work for you the offset to do it manually should be in the useful offsets thread.
