Code: ASM Resource Thread

[PufferJumps]

That is what happens when you just type make..

You need to be in the "build" folder directory...

Either use:
cd C:/User/"computername"/Desktop/Build
Then hit enter...
Now use the "make" command and as long as you have everything else installed like DevkitArm and Cygwin then it will work like a charm.

Hope this helps

Thanks for the reply. I actually tried what you said but, unfortunately I'm still getting errors :(

This is the problem that I'm getting:

Judging by this message, I think the problem was on.... ...DevKitArm?

I have those on my pc. As well as GNU Win and Cygwin. So, I dunno what's exactly the problem. ;-;

From what it looks like you need to add C:/Devkitarm/bin to the environment variables.
In Windows 7 go to "Control Panel\All Control Panel Items\System" then click on
Advance system settings then go to "Environment Variables" and click on it.

Now go down to "System Variables" and find "Path" then in the path add ";C:/Devkitarm/bin" to the path, also if check to see if Cygwin is also in the path....

Adding that to your environment variable will make it so you can call Devkitarm from the cmd.
You should also check if Cygwin is also in the path...
Without them in the environment variable path you wont be able to call them from the cmd.

If this don't help look on youtube on adding environment variable... That's how I figured it out awhile back

Hope this helps

Yassss!

I did some 'googling' (w/c I should've done from the start :S) and end up on the mega evolution hack. I follow the instructions there on how to redirect(?) the environment variable and finally able to make it work. Although it's quiet troubling because I use Windows 10 and all the tuts (including YouTube) are for 7.

Thank you. It helped me a lot. Happy Holidays ^^

Hey FBI, I know that maybe I shouldn't ask this being this directly and there's Visitor Profiles or MPs, but since it could benefit everyone I'll just go ahead: Do you think we'll ever see a freely usable Wonder Trade system or it'll stay exclusive to the community's ROM Hack forever?

 

[zoiwillxx]

REQUEST -

ASM for EMERALD

* COIL script to work like CHARGE, where the next POISON move deals additional damage.

* Dual typing "FIRE PUNCH", "THUNDER PUNCH", "ICE PUNCH", similar to how FLYING PRESS works.


Thank you and Happy New Year!

 

[Trev]

This is not a request thread. You can do all of those changes yourself with DizzyEgg's Emerald Engine Upgrade.

First of all, it's not 'real' Wonder Trade but rather Random Pokemon Generator Trade.
Secondly, the pokecommunity rom hack is open-sourced and all the code can be seen on github, including the trade system.

 

[zoiwillxx]

This is not a request thread. You can do all of those changes yourself with DizzyEgg's Emerald Engine Upgrade.

I know I can, I just don't know how, and I saw ppl making request in this thread already, I'm not demanding anything, just asking.

Maybe for you it's easy, but I don't know how to create a string for those moves on the engine. I'm in fact making a hack rom using his tool, but I don't know how to make those 2 things.

Would you mind making it or teaching me how to do it?

 

[Trev]

If you can't figure it out, the Move Resource Thread probably has an answer, as that thread is specifically focused towards the development and maintenance of moves. This thread is more for small, general ASM routines and not specifically geared towards solving move issues.

Pokemon Emerald Multichoice Scrolling Box

So, the mechanic for that is already implemented, we just have to repoint some tables. So let's get down to work.
First, there's a table at 0x085B2CF0. Each entry is a pointer to text to be displayed in the box. One set consist of 16 options. This is important. Anyway, repoint to free space and change pointers to this table. It ends at 0x085B3030.

Now, there's a jumptable at 0x813A156. It ends at 0x0813A19C. It has 12 entries, repoint it to free space. Now for every new set of options you want to add, you have to add a routine like this:

Spoiler:

.text
.thumb
.thumb_func
.align 2

main:
    mov r0, #5
    strh r0, [r3, #8] @how many are displayed
    mov r0, #8
    strh r0, [r3, #0xA] @how many are in total
    mov r0, #1
    strh r0, [r3, #0xC] @X coordinate
    mov r0, #1
    strh r0, [r3, #0xE] @Y coordinate
    mov r0, #9
    strh r0, [r3, #0x10] @unkown
    mov r0, #0xA 
    strh r0, [r3, #0x12] @box height, should be displayed * 2
    mov r0, #0
    strh r0, [r3, #0x14] @unkown 
    strh r4, [r3, #0x26] @task id, don't change it
    pop {r4}
    pop {r0}
    bx r0

Note that you can change parameters in those routines. Play with them and see which ones look the best for you. Now, every routine like that above, goes at the end of the repointed jumptable. There are 12-in game sets, so you'll start with 13. Change the byte at 0x813A148 to the amount of all sets.

One more thing, even though the table of pointers to text can only hold 16 pointers, it doesn't mean you're limited to only that many options. You can go to 126 max, because 127 is treated as hitting B. How? Well, in the routine above set how many in total to the amount you want and ignore occupied slots. For example if you want your set to have 50 options, divide it by 16, so you get 3 and some remainder. That means this set occupies 4 places in the jumptable, like this:
XX XX XX 08 00 00 00 00 00 00 00 00 00 00 00 00 NEW SET GOES HERE

Using it in a script is easy, just do this:
setvar 0x8004 slot in the jumptable (starts at 13, since 12 are already occupied in-game)
special 0x1BE
waitstate
Result is stored in the 0x800D. First option chosen is 0, second is 1, and so on. Hitting B be is 0x7F.
compare 0x800D 0x0
if 0x1 goto @first_option
....
compare 0x800D 0x7F
if 0x1 goto @chose_cancel

I hope everything's understandable. :)

Sorry to ask like I'm too dumb, but I would like to understand more on how things are gotten. I think replacing stuff in the ASM code needs a further explanation... especially on the bold parts I want to clarify because when I change it into something (trying out 32 choices... or maybe less), none seem to be appearing right.

Capturing a Trainer's Pokémon
With a Specific Poké Ball
Hello, when I insert the routine and follow the steps, this happens to me when I catch a pkm from a caster it becomes an egg and when I catch pkm the battle ends I hope they have the solution

 

[Froosty]

wanted to make a small request here.

Spoiler:

Well, this is what I did, while learning how to do stuff like debugging and doing new mechanics changes in the game.
Thanks to Touched-sensei, who helped me through the entire process. Thanks to daniilS and kleenexfeu, who also helped in the very end. This is for Fire Red:

REUSABLE POKÉBALLS

- First, go to 0xA1E30. Change 01 21 to 00 21 (with this, Pokéballs won't be deleted when you select them in your bag);
- Now, find some free space and insert this routine there:

Spoiler:

.text
.align 2
.thumb

main:
	bl deleteball
	mov r9, r4
	pop {r4-r7}
	pop {r0}
	bx r0

deleteball:
	ldr r0, var_800E
	ldrh r0, [r0]
	mov r1, #1
	ldr r2, =(0x809A1D9)
	bx r2
	
.align 2
var_800E: .word 0x0203AD30

Here's a compiled version:

Spoiler:

00 F0 04 F8 A1 46 F0 BC 01 BC 00 47 02 48 00 88 01 21 02 4A 10 47 C0 46 30 AD 03 02 D9 A1 09 08

This is the code that deletes the Pokéball;
- Finally, go to 0x2D924 and paste write this "00 48 00 47 XX XX XX 08" there. It's a hook to the routine you just inserted. Change the XX XX XX for the pointer to the offset you placed the above routine. Remember to +1 the offset before changing it to a pointer.

With this hack, you won't spend Pokéballs if you don't capture a wild Pokémon. I wanted to do it inspired in the anime.
Again, simple, some people will think it's a broken functionality, but it will do well for that time when you encounter a shiny Pokémon with that one single Pokéball in your bag. =P
Thanks again, everybody. Hope it's helpful.

I wanted this feature to be ported to emerald as well..
I think it would be only a short task of finding the proper pointers,
so if anyone would do it..
then not only me but other emerald hackers would also enjoy it :)
so it my request :)

I found that how frustration when playing some Emerald hack with bad egg/event corruption caused by usage of unsafe flag/var.
IDK if anyone had already port Jambo's routine to Emerald because I can't find any relevant post ATM.

	.hword 0x0183		@ illumise
	.hword 0x0182		@ volbeat
				@ theoretical new entries
	.word 0x0000FEFE

usage:
- table at the end has a structure:
[hword] - species 1
[hword] - species 2
an egg that is supposed to be species 1 has a 50% chance of turning into species 2 (note at the bottom), and it NEEDS to end with FE FE 00 00 as it does in the example.
- i included addresses for emerald and ruby as well. replace as desired (the hook address and the getparents routine address)
- you need to know where you are going to insert the routine BEFORE compiling it; the table is placed right after the routine and is referenced as such.

proof of concept:

Spoiler:

first from female bulba x male venusaur, second from male bulba x ditto, third from illumise and volbeat, last from nidoran(f) x ditto

shoutouts to doesntknowhowtoplay for his research on the subject and to chaotix for initial testing and suggesting the idea of a table instead of some extremely inefficient shtuff that was originally going to happen.

notes:
- species 2 does not ever turn into species 1. so you're breeding your volbeat to get an illumise? you'll only ever get volbeat. just add an entry for volbeat to illumise.
- if you want species 1 to turn into multiple species: i have been testing for literally five hours with the game running consistently at about 300% and have yet to see a phanpy come from my illumise. moral of the story: this code, even with modifications telling it to continue looping after setting the id, doesn't support 1 pokémon to multiple.
i did however manage to get illumise and this after doing like a weird chain thing (illumise -> volbeat -> phanpy), but it negated volbeat, and no we'd not like that:

- not tested on bpee or axve but there is no reason it shouldn't work (axve is the same thing while bpee i think interchanges two different registers)
- OH ALSO you have 0x2A bytes of unused space at 46070 for you to use for whatever! knock yourself out with all of that free space

There might be a better way to do this but as it stands I haven't seen it.

Also I am now putting all I have together and will release a custom Bank Account system that will include:
Pokemart Inflation/Deflation, Battle Money to Var (can store up to 4bytes or 0xFFFF FFFF) depending on setflag 0x250, ATM, Buffer 4byte number (though it can only print max 0xFFFF FF7F), Account Interest, Withdraw/Deposit/Balance and Loans.

Anyway hope this is helpful!

info:
1.This routine uses safe var 4011, 4012,8002 and flag 248 and 24c
2. Flag 248 is used to start the timer
3. 8002 is used to know how many minutes mission will continue
How to use:
1.insert this hook at 0x054894
00480047 xx+1 yy zz (xx yy zz is where u inserted the routine)
2.In The script which will start the timer based event you have to write this three line
setvar 0x8002 0xXX (XX = the minutes you want event to run )
setvar 0x4012 0xYY {YY = flag you want to set be if event is not finished in time )
setflag 0x248 (start the timer)
-------------------------------------
Now that you have started the timer this routine will run every second and when your given time in var 8002 is over it will set a flag (which is also given in var 4012). Depending on that flag in var 4012 you can determine mission is over / restart the mission / time over can't redo the mission etc.
Note: If player finishes the task in the mission you will obviously wouldn't want the timer to continue.So, clearflag 248 and 24C in that script
