Hi everyone, I've seen some people seeking for a way to add new trainer sprites in Fire Red instead of replacing, I don't know if it was posted, but I'm here to help that people.
You can only expand the trainer's sprites up to 255 sprites. (But it will be 0xFE because the 0x0 is counted too.) I tested and it already have support for 2 bytes indexes.

Tools used:
Spoiler:


First you will need to find the offsets of "Trainer Sprite Table" & "Trainer Palette Table":

Explanation about TST and TPT structures:

Hello, MBCN!

So I have made my first 6 sprites (of Pokémon) and I'm stuck with them, could you please help me?

I'm having that problem that says the "image is not indexed" or "it has no alpha chanel", and all I have done haven't worked so far (sometimes it simply ruins my art and still won't work)... I still don't understand this alpha/index thing.

I'm also using Photoshop CS6, please, tell me how to make these sprites useable!

Click to expand...

1- You need to have a sprite with only 16 colors (15 colors + 1 background);
2- To index your sprite go to Photoshop CS6, Image > Mode > Indexed Color > OK;
3- If your sprite don't have 16 colors, open it on IrfanView, Image > Decrease Color Depth... > 16 Colors (4 BPP) > OK.

If your sprite have a lot of colors like 20 or more, some colors will be replaced, then you have to fix on IrfanView to have more compatibility, remember to leave the first color of the Palette on IrfanView as the background of the sprite.

Hello i never wanted to make this post but i am really stuck still new to this hacking i really wanted to figure this out on my own but idk whats wrong so let me explain.

im almost 100% sure i repointed TST and TSP Correctly becuase i can see my new trainer sprite i added in slot 148 HTE so im pretty sure its in the game but the problem is when i go to battle the npc ingame the npc that im fighting has my new sprite and It freezes right before the battle shows the sprites i thought it was becuase i was using a custom sprite so i got my clean backup and exported a stock sprite and made a new slot ON MY CLEAN BACKUP using that STOCK sprite and i get the same results plz help im using (FSF)-(HxD)-(HTE)-(NSE 2.0) idk if its how nse is inserting sprites OR the free space im using or using old version of one of these programs as i siad im new to this hacking stuff any help would be appreciated as i really wanna add new sprites without replacing old ones.

im pretty sure its not my firered tried 2 diffrent ones but i will try again if suggested

TL;DR
Battle sprites on newly created slots freeze in battle no matter what the sprite is stock/custom am a newby could be user mistake but double triple checked so doubtfull plzz n thank u

Have you expanded the Trainer Animation Table? It's needed to work in-battle.

You can find the Trainer Animation Table repointing at the bottom of my thread.

lm so frusterated right now i dont understand i moved the animation tables and repointed them in the offsets you said in the thread so im almost sure im doing this right (i could not be) but now every sprite freezes ingame cant battle any sprite so i must be repointing wrong or something i almost thought it would work its probably user error witch makes me even more mad if you can help let me know

EX of me repointing TRAINER ANIMATION TABLE 3:

Go to offset 23932C copy from starting byte to (92 bytes / 250 in Hex)
Then find and write over open space OFFSET: A3A450 (bunch of FF's)
Replace pointers (4 bytes) at OFFSETS: 0x37E78, 0x3804C, 0x3CAD4 and 0x158514
with POINTER: 50 A4 A3 08

(LET ME KNOW IF IM REPOINTING WRONG)
plz and thank you for your time

First, 592 bytes instead 92, then you cannot only repoint, you have to add more bytes on each table, you must read it with patience:
Code: 
Inserting new trainers:

It will be the easiest step of the Trainer Animation Table, you only need to copy the last 4 bytes of the second and third table, and paste at the end of them respectively. That's it, you're now ready to use your new trainer sprites.
To understand anything, read, read and read.

You can only expand the trainer's sprites up to 255 sprites. (But it will be 0xFE because the 0x0 is counted too.) I tested and it already have support for 2 bytes indexes. I tested only up to 512 (0x200), but I will try higher indexes to know if the max number is 0xFFFF or if there is a limiter.
