Code: [EM] Items, TMs, Tutor Moves Expansion

[Trainer 781]

It's me again guise guys.

As the title says, an easy way to expand Items, TMs and Tutor Moves. If you're familiar with how I do stuff, you'll probably know that I use python scripts and C/asm code. This time is no different. You set the parameters you want and run a python script that does everything.

How to use it?

Spoiler:

- Download the repository by clicking on 'clone or download' then 'download' zip.
- Unpack it somewhere, open the file items.py in the scripts folder. There's a bunch of lines to be edited with a short description provided, so I think it's pretty clear.
One thing about the EXPANDED_BAG_OFFSET label.

Spoiler:

It's a memory address to be used for additional bag space if you expanded TMs or a pocket's size. The provided address is what I believe the starting point of unused RAM space. If you have no idea about RAM and all that stuff, keep it, but also keep in mind that:

- you need to expand the saveblocks, you can use my method in the poke expansion thread, JPAN's hack or whatever you want

- if you used my pokemon expansion script, the value for dex flags is the same as here, so that needs to be changed.
Add X to that address, where X is the:
(DexPokes / 8)(rounded up) + (DexPokes / 8)(rounded up)
That is, so the space for new pocket items and dex flags do not overlap

- Expanding pockets size means the space that was used previously for it is now freed and can be used for whatever purposes you want.

If you're not sure what to do, feel free to ask.

- After you're done editing, put your rom in the master directory, rename it to 'rom.gba', open the cmd, type "python scripts//items.py" and the script will run.
- A new rom 'test.gba' will appear and 'offsets.ini' and 'functionoffsets.ini files will get updated.

sweet m8!
glad you're doing a ton of emerald stuff :D

 

[Megax Rocker]

At this point emerald seems to be the best rom to hack, great job.

So after I apply this how would I be able to change the names of the TMs for 51 and downward?

 

[Marky Vigoroth]

Will this also work with HMs?

You mean the Item names? Those can be changed in any item editor.
As for the moves that TMs hold, they're in the TM_move_table.

Will this also work with HMs?

Yes, it can expand HMs too.

I didn't understand that "One thing about the EXPANDED_BAG_OFFSET label" part. I used your pokemon expansion to insert 801 dex entries. So what i have to change in this script?

Take the offset in pokemon expansion. Divide your dex entries by 8 and add 1 to it. Add the result to the offset you took. Make sure it ends with 0, 4, 8 or C(if it doesn't just add 1 till it does). This is your expanded_bag_offset. :)

Please can you tell me which offset you are talking about... Is it the dex table on or another one? Please answer me...

I was talking about this offset in the BPEE.ld in poke expansion
new_saveblock = 0x0203CF64;

Sorry if it wasn't clear enough,

 

[Volcacross802]

For some reason when i type "python scripts//items.py" into CMD, it says:
python: can't open file 'python scripts//items.py': [Errno 2] No such file or dictionary

What do i do about this? also right when i open python, it immediately closes, what do i do?

 

[Volcacross802]

I have a question, how do you put on multiple scripts? I want to figure that out.

I'm sorry I don't understand the question. What do you mean?

 

[Volcacross802]

Well, I found out how to get your Battle engine upgrade working, how do i get this to work as well?

The process is pretty much the same, except here you config the script file as said in the first post.

What does "Number of TMs can not exceed number of new items" mean?

 

[DizzyEgg]

What does "Number of TMs can not exceed number of new items" mean?

It means there's not enough items to hold TMs.

 

[Volcacross802]

So, Uh, i got this added in along with the battle engine upgrade, however when i look at the TM list, there's all these random letters instead of empty spots, is it supposed to be like this, or did i do something wrong.

It's been quite a while since I've been active around here (life just doesn't give me the same amount of time for things anymore), just want to say thank you for your amazing tools. I would love to see all these things come together in an editor.

This is probably a very stupid question, it's been a while and I have so much to relearn, I don't even know where to start. If I remember correctly, items of particular usage are in indexes, for example to create a new evolution stone you would need to rearrange things and repoint items in the index. Am I dreaming that this was a thing? In your tool you can specify how many TMs and HMs you want but I see no options for any other items. Are there new methods for adding items that I'm unaware of? Or is it still up to the individual user to expand all the other item types? And if so, where could I come across the information necessary to do this successfully?

This script expands items by creating new slots and adding them at the end of the table. It means that the items themselves have to be added by the user in an item editor. TMs are different, because they require changes to the game code, particularly bag.
I'm also not sure what you mean by 'expanding all the other item types'. Things like Berries or new poke balls would take some work, because they're not ordinary items. But all other items is just a matter of putting values in an item editor.
