[Fire Red] Adding New Trainer Sprites

[mbcn10ww]

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:

HxD (Hex Editor)
FreeSpaceFinder
NSE 1.7.5.0
HTE - Hopeless Trainer Editor
Photoshop CS6
Irfan View

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

Spoiler:

The offsets of the pointers are:

TST = 0x3473C (here you probably find the original pointer - 7C 95 23 08 = table offset 0x23957C size 1184 bytes / 4A0 in Hex)

TPT = 0x3474C (here you probably find the original pointer - 1C 9A 23 08 = table offset 0x239A1C size 1184 bytes / 4A0 in Hex)

Explanation about TST and TPT structures:

Spoiler:

Trainer Sprite Table
Each sprite have 8 bytes of data = BC 90 E4 08 00 08 01 00

BC 90 E4 08 = pointer to the sprite
00 08 = must be unmodified, some have 00 10 instead but I don't know what is it
01 00 = half word ID of the trainer image

Trainer Palette Table
Each palette have 8 bytes of data = 1C 94 E4 08 01 00 00 00

1C 94 E4 08 = pointer to the palette
01 00 = half word ID of the trainer image
00 00 = unused, always 00 00

Repointing:

Spoiler:

You have to repoint those tables in some free space, I will use the following offsets for Sprite & Palette respectively:
TST = 0x990000
TPT = 0x996000

Place pointers to the TST (00 00 99 08) at:
0x3473C
0x347A4
0x37E8C
0x38060
0x3CAE8
0x838E4
0x83928
0x10BC3C
0x158528

Place pointers to the TPT (00 60 99 08) at:
0x3474C
0x347A0
0x37E88
0x3805C
0x3CAE4
0x838E0
0x8392C
0x10BD1C
0x10BD3C
0x10BD7C
0x158524

Adding new sprites:

Spoiler:

First you will need a 64x64 trainer sprite:

1- Index it with Photoshop and make it 16 color or lower with Irfan View.
2- Now find some free space for sprite and palette, open that free offset on NSE, load the trainer image, then insert it compressed. (Remember to save the offsets of the sprite and palette.)

Inserting at the tables:

Spoiler:

Remember the data structure of each table? You will use that now.

The total amount of trainer sprites present in each table is from 0 to 147 (0 to 93 in Hex).
You must have to add only 8 bytes for a new sprite/palette in each table:

Trainer Sprite Table:

Spoiler:

XX XX XX 08 00 08 94 00

XX XX XX 08 = Reverse pointer to the offset of the new sprite
94 00 = half word ID of the new trainer image - 148 (94 in Hex)

Repeat it until you reach the desired number of new trainer sprites.

Trainer Palette Table:

Spoiler:

XX XX XX 08 94 00 00 00

XX XX XX 08 = Reverse pointer to the offset of the new palette
94 00 = half word ID of the new trainer image - 148 (94 in Hex)

Repeat it until you reach the desired number of new trainer palettes.

Using on editor:

Spoiler:

I use the Hopeless Trainer Editor (HTE), it is the most simple thing to do, just open the .ini of your editor and look at [BPRE] and you will see "NumberOfTrainerSprites=147", change the "147" to the new amount of trainer sprites you have. Finally, go to your editor and you will see the new trainer sprites there.

Trainer Animation Table:

Spoiler:

Needed Tables:

Spoiler:

The offsets of the tables are:
0x238E8C (592 bytes / 250 in Hex)
0x2390DC (592 bytes / 250 in Hex)
0x23932C (592 bytes / 250 in Hex)

Repointing:

Spoiler:

The first table (0x238E8C) don't need to be large as it is, we just need 4 bytes for it because it have only pointers to the same offset, you can fill that table with FFs if you want:
Find a free space (0x989796) then put E8 47 23 08, save the offset.

The second table (0x2390DC) have the pointers to each pointer on the first table, then if you have repointed the first table using only 4 bytes, the second table only needs pointers to the offset of the first table, fill all of it with your reversed offset like this 96 97 98 08, then repoint this table to some free space, and place a pointer at 0x3F8F4 and 0x10BDA8.

The third table (0x23932C) is filled with 08 01 00 00, only four of them are 08 02 00 00, but that four are unused trainers then you can change it to 08 01 00 00 too, but I don't know if it will affect anything, then repoint that table to some free space and place a pointer at 0x37E78, 0x3804C, 0x3CAD4 and 0x158514. (You don't need to repoint this table because of many repoints we made it will have free space at the end of the table.)

Inserting new trainers:

Spoiler:

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.

I hope I have helped all the people who were looking for this tutorial.

very good
Can you tell if it works with thainers with animated sprites?

very good

no reason it shouldn't
this is just expanding the table of trainer sprites shown, the animation table shouldn't be affected~

You're totally right.

 

[Wesley FG]

You're totally right.

you test the new trainer sprites ?
because sprites above the original number (147) will freezer the game,
check it yourself, you need to extend the trainer table animation too,
have one animation for each trainer sprite.
i explain everything here:

Now I've added the Trainer Animation Table repointing.

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!

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.

no i have not thank you for the quick reply i will try doing/learning that right now if its repointing thoes animation tables here on this thread then i can do that

(expand=repoint?) ima newbey remeber.

but ima repoint thoes right now give me 30m

will report back

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:

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.

thank you for your time so i supppose im repointing right never got it to work just cracked and replaced existing B-sprites but i will take a try at this again one day thanks for your help

 

[mbcn10ww]

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.
