Alright I'm making a request!
Everyone has probably heard about Bank system...
On which can allow the player to store his money, loans, interest (ofc in support with primes RTC) and other cool banking stuff.
PS this thread has helped me a lot thanks "A free helper" Blah ;) !

read the op please <3

Aight, this request is similar to shinyquagsire's berry selection screen...
I need an asm which can show the party screen and on selecting the pokemon, exits and stores data in a var...
However theres a twist, im not talking about special 0x9f...
The mons need to be read from Ram where PSS stored the mons... So now y'all get it why its so complex...
If that is to be pulled off, it'd be amazing;)

legit take the routine for special 0x9F
replace the part where it accesses your party with the new ram address. this likely just involves replacing an address from the routine, literally nothing more. callasm the new special and ezpz

Say I located the routine, but how do u decompile the routine in hex to actual asm???

two easy ways
look in knizz's idb
disassemble in vba

Someone can convert it for EM ?

Change the order that badges appear on the trainer card (untested)
Simply makes the loop read from a lookup table before checking for the badge.

Is it possible to alter the breeding mechanism in FR? Having the egg be only be the mother's species and inherit moves from only the father is limited.

I'm thinking of the egg having a 50% chance to be either species instead, so that male only pokemon would still breed normally, and egg moves would be possible for them as well.

Would probably be much better than the regular one IMO.

i test and not work

MKCocoon · Oct 17, 2017

I have a request:

So FireRed's egg move table only accounts for 8 egg moves. My hack, Pokemon Vega Minus, is obviously derived from the original English translation of Vega by Dr. Akimbo. The problem is, egg moves are busted in both my hack and his because in Vega, Pokemon have anywhere from 15 to 37 egg moves.

So I was able to fix it somewhat by replacing the 0x9 at 0x0456AC with 0x30 (just an arbitrarily large number), and then fixing the limiter at 0x045CC4, but since the amount of RAM allocated to egg moves only can account for ten moves without overflowing, I'm worried this could result in glitches.

In this thread, FBI explains how to fix the crappy way the game checks for egg moves using ASM, except since I know nothing about ASM, it doesn't make any sense to me. Apparently it's simple for people who do understand ASM though, so if anyone could help me out it'd be great. You can go download my patch for reference if needed. I'd also need to know how to implement the ASM into the game.

Thanks in advance.

I just tested it, and it does.

1) Copy the routine and paste it in a .txt file, change the order however you want and give the file an easy-to-remember name.

2) Pass it through HackMew's thumb.bat

3) Grab the compiled routine from its .bin file and paste it in an offset that ends in 0, 4, 8 or C and that also has free space in your ROM.

4) Go to the offset 0C4684 and Paste-Write (Ctrl+B) this:

Code:

00 4B 18 47 XX XX XX 08

XX XX XX = Pointer to the offset+1 where you've inserted the routine.
Example: I've put it in E3CF80, then I'd replace XX XX XX with 81 CF E3.

5) Test.

i know compile and insert asm routines, and i test it again and not work,
you can post the hex compiled bin generate for you:
for my it:

07 14 11 31 03 A0 C0 5D 09 18 08 78 00 4B 18 47
8D 46 0C 08 07 06 03 02 05 04 01 00

and not work, you really check it ?

to be honest i don't understand why this would even be necessary; just replace the graphics if it's really not working for you, although i regrettably inform you that i think lunos is right as i also tested it myself, so... yeah

you change some badge of position, for test ?
i change the 5th with 3th (for use surf after 3 gym)
and 6th with 4th (for use fly after 4 gym)
and my changes no have any efecct, the badges apppear in the same order

this has no effect on how the badges are awarded, in what order in the game's story, or which badge awards which move. this solely affects in which order the badges show up on the bottom of the front side of the trainer card

yes i understand all, i change the order of 3 badge with 5 badge, and no have effect in game.
the badges are same original positions.

Also, I'm seeing that you have an empty space after that 00, delete it.

can i run a ASM routine forever in second plane? how?

ghoulslash · Oct 22, 2017

Here's kind of a silly routine I made for fun.

Custom Vs. Seeker Pedometer [FR]

This will let you change the amount of steps needed to activate the vs. seeker. You can make it step-independent, increase or decrease as the game progresses, or have some random fluctuations, or anything you like.

It requires 2 bytes of free RAM. JPANs save block hack is needed to allow the pedometer to save. The first byte will hold the pedometer value, and the second will hold the 'charged up' limit. When the pedometer reaches this value, the vs. seeker is usable, and then reset upon use.

To change the required steps, just set your second RAM byte to whatever you like. This can easily be done in XSE. Just be sure to set the limit when the player receives the item.

Note: I'm not sure if this is an existing Vs. seeker feature or not, but using it even when there are no trainers are around resets the pedometer. Although from a logical standpoint this makes sense regardless.

Now, for the routines! There are two of them you will need. (insertion instructions in comments of each routine)

First: Change Vs. Seeker Routine to Check our new Pedometer

Spoiler:

Second: Increase pedometer each step (you will have to merge with the hp loss/gain each step routines)

Hello,

I know this is something which has been requested by others before, but I would like to request a way to store the current hp of pokemon being deposited in the pc storage system.

This would allow us to control any way in which a pokemon can be healed.

Spoiler:

I don't know enough asm to evaluate how hard this would be to implement, but it would be a very good function to have, as it would allow a lot more flexibility with the kind of game-play changes you could implement.

Lunos · Nov 10, 2017

Hi, I wanted to make a request. I don't know if it's simple or not but I hope it is.
I'd like an ASM Routine for Fire Red, that checks a Pok?mon in your party and returns 0x1 in the var 0x8004, if it's an egg. Would that be possible?

I'm basically thinking in a script that forcefully hatches an egg.
Right now, if someone decided to make such a routine, I imagine that it could be used like this:

Code:

special 0x9F // Pick a Pok?mon
waitstate
callasm 0x8XXXXXX|0x8XXXXXX+1 // This would check if the Slot that the Player picked in the special 0x9F is an egg or not, and if it is, it would set to 0x1 the Var 0x8004. 
compare 0x8004 0x1
if 0x1 goto @hatch

#org @hatch
special 0xC2 // Hatch the egg

There is actually already a special in Firered that checks if what you chose is an egg or not.
Usage:

Code:

(...)
special 0x9f
waitstate
compare 0x8004 0x6
if 0x4 goto @cancelled
special2 0x800d 0x147 - this is the special
compare 0x800d 0x19c - check if egg
if 0x1 goto @itsanegg
(...)
