[Delta231]

There are unused surf sprites for Players that use Lapras-like blob. More info could be found here. I found it when when finding something else. Each frame is 32x32.

Address: 35FFA8 35BFA8
Palette: 35B968

EDIT: Oops, seem like the address is 35BFA8

 

[kalarie]

@Delta231 The correct offset is 0x35FBA8;)

Something else: The ''warp6'' (0xC4) command in XSE sets where the player will warp when using an Escape Rope or uses Dig.

Didn't see this documented anywhere, so I thought I'd share it here.

Decided to get back into hacking recently after a brief hiatus. Here's a quick something I had been interested in a while ago but never got around to looking into until now.

Expand Trainer Class Name Length: (Fire Red)
Class Names Table Pointers:
0xd80a0, 0x11b4b4
Class Name Size (originally 13 bytes):
0xd8092, 0x11b358

The old name table will be useless, so you will have to make a completely new one (or re-structure old one)

It's been a while, so i don't think this should cause any text to run off screen anywhere, but I could be wrong.

 

[Jaizu]

I edited the berry script of pokémon emerald, so you can replant berries after picking one.

Edited: Fixed it. Tomorrow I will add the wailmer pail stuff. Sometimes when you compile text breaks. Just open your script and replace the texts with the original ones, and it will get fixed.

Evolution Moves [FR]

I apparently forgot to post this here when I finished it a few months back.

Basically, it adds in support for Gen VII-style evolution moves. These are moves that are learned upon evolution, regardless of what level the evolution happens on. A Pokemon can have multiple evolution moves (like Lanturn).

Selphy's Random Items [FR]

At 0x83F5B30 is an array of 6 item indexes of items that Lady Selphy may give away when you show her a Pokemon.

This does not include the Luxury Ball. special 0x15D looks at this array if the Luxury Ball isn't chosen and randomly picks one and puts it into var 0x403B.

The very well-known tall grass fix found here had a minor bug involving the Cycling Road/Route 17 grass have the tall grass animation as well.

The problem was that it was looping back to comparing the grass with D1 as its behaviour byte right after comparing 03 for the tall grass. This resulted in D1 grass taking on the tall grass behaviour byte. The correct loop is the one where 1 is put into r0 and then returns to its callee.

The completely fixed tall grass fix is:

00 21 00 06 00 0E 02 28 01 D0 D1 28 01 D1 01 20 00 E0 00 20 00 21 70 47 03 28 FB D0

pasted at 0x8059F34.

The fix was actually the last two bytes being changed from F5 E7 to FB D0 to fix the looping back only when the behaviour byte is 03.

Personal Researches
1. Bug fixes and improvements in "Making the 'seen' amount of Pokédex displayed in the 'Continue' screen and the save screen instead of the caught numbers":

Spoiler:

(a) In addition to Jambo51's post, to make things work in a Trainer's Card in FireRed, make such modifications:

0x808A0EA: [B]00[/B] 20 @ 01 20 originally
0x808A0F2: [B]00[/B] 20 @ 01 20 originally

(b) In Ruby, make such modifications:

[S]0x808C43E: [B]00[/B] 20 @ 01 20 originally[/S] (Edit: Sorry, don't change this value or the caught amount will be displayed as the seen amount.)
0x80948D6: [B]00[/B] 20 @ 01 20 originally
0x810D450: [B]00[/B] 20 @ 01 20 originally

2. Adding the Fairy type into Ruby without replacing or damaging contests:

Spoiler:

Step 1: Read destinedjagold's original thread of inserting the Fairy type into Ruby; (It is flawed because some contest conditions are overwritten)

Step 2: Read MrDollSteak's original thread of inserting the Fairy type into Emerald;

Step 3: Obtain the type chart in MrDollSteak's tutorial. Insert it into free space as a 16-color compressed image;

Step 4: Repoint the icon position table (in Ruby, it is at 0x83C115C). Follow Parts 1-5 to 1-8 in MrDollSteak's tutorial, but remember you are hacking Ruby instead of Emerald, hehe;

Step 5: Modify strength and weakness chart and repoint in-battle type names. Follow the instructions in either tutorial;

Edited 11/13: Need an extra Step 6: Expand and repoint the table at 0x83F59C8 for Pokédex search functions (by type). There is not such a table in Ruby as that at 0x82F029C in Emerald so just ignore it.

Credits to destinedjagold and MrDollSteak.

3. Implementing a "Town Map" item in Ruby and Emerald:

Spoiler:

Step 1: Read Chaos Rush's thread of "Useful Emerald Stuff". Step 3A is taken from this;

Step 2: Load the ROM LSA - Complete Item Editor;

Step 3A: In Emerald, navigate to item 0x169 (Town Map). In the "Field Effect" function of the "Usage" tab, select "custom" and put 08138C95 in the address box. Save;

Step 3B: In Ruby, we must choose an unused item, e. g. 0x34. Rename it to "Town Map" and insert its description. Then, In the "Field Effect" function of the "Usage" tab, select "custom" and put 0810E415 in the address box. Save;

Step 4: Test it out! (Note: After the map is viewed, the screen will revert to the overworld instead of the bag)

Explanation: Calling special 0xFB in Ruby or special 0xFE in Emerald will bring up the Town Map.

Credits to Chaos Rush.

4. Extending Trainer Class name length limit in Ruby and Emerald:

Spoiler:

Decided to get back into hacking recently after a brief hiatus. Here's a quick something I had been interested in a while ago but never got around to looking into until now.

Expand Trainer Class Name Length: (Fire Red)
Class Names Table Pointers:
0xd80a0, 0x11b4b4
Class Name Size (originally 13 bytes):
0xd8092, 0x11b358

The old name table will be useless, so you will have to make a completely new one (or re-structure old one)

It's been a while, so i don't think this should cause any text to run off screen anywhere, but I could be wrong.

(a) In Ruby, the Trainer Class name table is at 0x81F0208, and the length limit byte is at 0x812171C.

(b) In Emerald, the Trainer Class name table is at 0x830FCD4, and the length limit byte is at 0x814F15C.

Wonder Trade with NPC Trainers [FR]

Basically, this is a WT system that uses the NPC trainer data as the pool of potential trades. It picks a random trainer, and a random slot from that trainer's party, and that's what you get traded.

The repo is here.

In case it's not obvious, this includes the actual trade animation, and the Pokemon in question will keep the NPC trainer's OT ID and OT Name, as well as any held item and custom moves it may have assigned to it.

Additionally, if the Pokemon you receive evolves by trade, it will evolve when you get it. Trade + Held Item evolutions would work as well, but I doubt there are many NPC trainers that have Scythers with Metal Coats (for example).

A few things to keep in mind if you decide to use this:

• You could end up with a Nat'l Dex Pokemon early. You'll probably want to enable foreign Pokemon trading and evolution, assuming you aren't simply giving out the Nat'l Dex at the beginning of the game.
• Some NPC trainers such as Giovanni have names that are too long to fit in the OT Name field. These trainers are excluded from the pool.
• Any Pokemon that isn't included in a team of an eligible trainer can't be received at all.
• It is possible to get the same Pokemon multiple times.
• You'll probably trade with a lot of people named GRUNT.

When I edit the tdan with the command python scripts/makinoa I recived this error message :S

The routine does not give experience when using movements like absorbs, mega drain or giga drain, in addition to giving experience without having the active flag, also I do not know if the var is the correct one.

I'm confused on hex locations here. We all know the game doesn't code past a certain part in its allotted space (roughly 0x700000-0x800000, or whatever). Can someone help me make sense of the locations mentioned in this quote?

For anyone that wants to change the badge required for surf, the offset of the flag is 0806D59C. Also, I'm pretty sure that 0806D5D0 is waterfall, but I haven't tested it. (FireRed)

0806D5D0? Is this just 06D5D0? Or am I missing something here because I feel like I see these large offsets that I can't CTRL+G often. Thanks.

The 08 prefix says that it is part of read-only memory (ROM). So if you see 08xxxxxx, it means you can find the offset in your hex editor by dropping the 08 in front. So you are correct, 06D5D0 would be the correct offset.

Anyone know how to go about giving Pokémon a chance to flee when in the wild, like they would in the safari zone, where it checks the Pokémon's 'run rate'?

I've located a table that is possibly useful for ASM hackers (certainly those doing abilities). It controls the end of turn effects that tend to do damage such as Leech Seed, Burn, Poison and Nightmare (among other things).

In Fire Red it is located at 0182FC, and in Emerald at 0409C8.

I'm compiling a list of effects that will correspond to the relevant 4 byte entries (they're just pointers that get loaded).

Spoiler:

Entry 3 - Leech Seed Damage
Entry 4 - Poison Damage
Entry 5 - Toxic Poison Damage
Entry 6 - Burn Damage
Entry 7 - Nightmare Damage
Entry 8 - Curse Damage
Entry 9 - Wrap, Fire Spin, Whirlpool, etc. Damage

Can we expand and repoint thi table so we can add new one? If so, does it have any limiter?

To make the bike's usability in Firered be based on map type instead of the 18th byte in the map header structure, paste-write at 0x55C9C:

00200449C97D052902D0082900D0012070470000FC6D0302

Source:

Spoiler:

.org 0x55C9C
mov r0, #0x0
ldr r1, =(gMapHeader)
ldrb r1, [r1, #0x17] @mapType
cmp r1, #0x5 @underwater
beq bike_return
cmp r1, #0x8 @inside
beq bike_return
mov r0, #0x1
bike_return:
bx lr
.align 2, 0
gMapHeader: .word 0x02036DFC

After this, instead of having to set the 18th byte manually in the map header each time you create a new map, you just need to set the correct map type.
As far as I know, this doesn't affect any bike-able maps already in the game except for the Underground Path which is set to Inside, but you can change that easily.

Is there a routine to implement double wild battles in FR? I haven't seen this mechanic posted in the index.
