Patch: Battle Backgrounds Patch for Fire Red

[LibertyTwins]

We've created a patch that inserts 20 unique, no-platform battle backgrounds into Fire Red! These backgrounds provide a variety of beautiful, detailed scenes, replacing the vanilla backgrounds. This patch also includes the Tall Grass & Micro Grass Fix by knizz.

Here's a list of backgrounds included in the patch:

Spoiler:

• Grass
• Forest
• Sand
• Icy Cave
• Sea
• Pond
• Mountain
• Cave
• Lab
• Route
• Neutral (No scenery)
• Indoors
• Battle Arena
• Snow
• Snowy Mountain
• Desert
• Volcano
• Town
• Graveyard
• Space

[*]

Compatibility:
This patch is for Fire Red only and uses offsets C0C7E0 - C2CFOD.
If you want to use these backgrounds for Emerald, or have them located in different space, all of the images and palettes can be found in our GBA Sprites Pack.

Screenshots:


The screenshots above show all of the battle backgrounds in the patch. We've aimed to include a variety of backgrounds to cover any possible scenery that could appear in a ROM hack.

How to use:

Spoiler:

Apply the patch to your ROM. This will overwrite the vanilla background graphics. It will also edit the "fighttype" table and update the vanilla maps to use the correct backgrounds
Of course, if you're creating your own hack, you'll need to know how to select the right backgrounds for your maps. This is explained in detail below…

Battle Backgrounds are determined by one of 3 things:

• Tile Behaviour Bytes - which load some backgrounds depending on what tile the player is standing on
• Map Types - which load a few backgrounds depending on the map
• Fight Type Table - which will always load the set background regardless of the other bytes/types

Where possible, we've replaced the vanilla backgrounds with ones that resemble the same scenes (e.g. grass is replaced with grass, cave is replaced with cave). However, due to the variety of our backgrounds, we have to take advantage of the Fight Type Table to be able to use all of these.

Here's how you can call each of the backgrounds in game:

ID​

Name​

What you need to set (to use the background)​

0​	Grass	"Tall Grass" behaviour byte (default)
1​	Forest	Fight Type 2 (Evil Team in HMA)
2​	Sand	"Sand" behaviour byte (default)
3​	Icy Cave	"Underwater" map type (unused in FR)
4​	Sea	"Water" behaviour bytes (default)
5​	Pond	"Pond Water" behaviour byte (default)
6​	Mountain	Fight Type 3 (Unknown in HMA)
7​	Cave	"Cave" map type (default)
8​	Lab	"Indoor" map type (default)
9​	Route	Default when nothing is set (applies to most outdoor trainers)

10​	Neutral	*Unused (hard-coded to Trainer Tower)
11​	Indoors	Fight Type 8 (Big Red Pokeball in HMA)
12​	Battle Arena	Fight Type 1 (Gym in HMA) (hard-coded to Gym Leaders)
13​	Snow	Fight Type 4 (Elite 1 in HMA)
14​	Snow Mountain	Fight Type 5 (Elite 2 in HMA)
15​	Desert	Fight Type 6 (Elite 3 in HMA)
16​	Volcano	Fight Type 7 (Elite 4 in HMA)
17​	Town	*Unused
18​	Graveyard	*Unused
19​	Space	*Unused (hard-coded to Champion)

The above can be easily set by editing map headers inside of HMA. HMA will refer to Fight Types as Battle Types when editing the Map Header data.

*Unused backgrounds can be used by editing the Fight Type Table. Despite the fact that the table can be extended in HMA, only the first 8 slots will work in game, so you'll need to decide which background you won't be using and replace its slot in the table with the ID of your desired background.

Is there a way of using this without HMA?

 

[LibertyTwins]

Yes, u can just apply the patch using Lunar IPS and it will insert all of the backgrounds for you. HMA is just my recommendation if you'd prefer to insert them manually into different space

Is there a way of using this without HMA?

This is a really mod to use. I sadly just got one issue with this: All battle backgrounds from the category "fight type" (advanced map name) or "battle type" (hma name), won't show up immideatly when the battle starts. There is another battlebackground like route or indoor first. Only when I enter the bag or the party menue and then return to the battle screen the background actually changes. Is this a known bug? Or do you by any chance already know a way to fix this? Thanks a lot!

I assume ur using the CFRU? The patch works fine on a vanilla ROM but unfortunately the CFRU will cause this bug. I'm trying to fix this myself so I'll let u know when i find out how, but i believe it involves editing battle_terrain.c

Thank you for that fast response! yeah I am using Hubol which technically is cfru. And no worries, for now I just play with less battlebackgrounds then, as the others seem to work completly fine.
And thanks! I will make sure to frequently check on this post then for a possible update :)

Sorry I have a problem, when I want to choose the Battle Type, well for the moment I have only tried it in the elite 4 but when I try to choose its background for some reason it does not change within the game but in HMA, I am using HUBOL, Also when I open the inventory in any combat the map changes, Regards.

Thats a problem with the CFRU unfortunately - you'll probably find that if u go in and out of another menu (such as the party menu) then it should correct itself to the right background. Something I'm hopefully able to provide a fix for soon but it's a CFRU problem with fighttype bytes not a problem with the patch
