Code: [EM] Dizzy's Hacked Engine

[Trainer 781]

I present to you a bunch of features that some people were requesting and some that I decided to port/upgrade. Those are relatively small projects and I hope to add new ones as time goes on.

Github page link

Current features are: (thanks for Tetra for writing descriptions of some of them)
Upgraded BW's Repel system

Spoiler:

Similarly as in the Black/White series, you will be prompted to use another repel upon expiring. I added an option to choose which kind of repel to use provided the player possesses at least two.

Spoiler:

Playing specific music in a battle

Spoiler:

WildPokeBattleMusic - allows you to assign a song that will be always played upon coming across a pokemon.
It uses the padding bytes in pokemon basestats. If 0 it'll play normal encounter music.
TrainerMusicVar - a var of your choice, it should contain a song ID that you want to be played in a trainer battle. If the var is set to 0, music plays normally.

Competitive Trainers:

Spoiler:

Similarly as Doesnt's EV Trainers my method works by setting the "EV" byte in trainer pokemon's data. It allows you to set pokemon's EVs, IVs, nature and pokeball. Only trainers that use pokemon with custom moves and custom items are affected(note that even if you assign custom items, a pokemon can still hold nothing).
The layout is like this:

Spoiler:

hp/atk/def/spd/sp.atk/sp.def ev
hp/atk/def/spd/sp.atk/sp.def iv
ability(0 for first, 1 for second)
nature (enumerated like this)

Spoiler:

0 HARDY
1 LONELY
2 BRAVE
3 ADAMANT
4 NAUGHTY
5 BOLD
6 DOCILE
7 RELAXED
8 IMPISH
9 LAX
10 TIMID
11 HASTY
12 SERIOUS
13 JOLLY
14 NAIVE
15 MODEST
16 MILD
17 QUIET
18 BASHFUL
19 RASH
20 CALM
21 GENTLE
22 SASSY
23 CAREFUL
24 QUIRKY
Other values will make it random.

pokeball
padding byte

You can have up to 255 different sets. Note that the first set is assigned by byte 0.
The table of sets gets created upon building the project. You can find its location in the offsets.ini file by name "config_table".
Here's an image of a trainer sending out his pokemon with a master ball:

Spoiler:

Max Money 9 999 999:

Spoiler:

Moves the money cap from 999 999 to 9 999 999. A simple hack, although required a hook for properly displaying money while buying items.
Images:

Spoiler:

New Evolution Methods:

Spoiler:

All(I think) new evo methods have been implemented.
If your hack has 8(or more) evolutions per pokemon change the "EvosPerPoke" line in the build.py script.
However instead of expanding entries, I present a better solution below.

Eeevee evolution Table:

Spoiler:

Instead of expanding the evolution table from 5 entries to 8, this feature now creates a new, special table that is used for
Pokémon that need more than 5 entries. An example of this is Eevee, who has 8 evolutions. This feature was implemented to save space
and only give more entries to Pokémon that need it.

Spoiler:

Nature Colored Stats:

Spoiler:

I wrote an ASM routine(that can be found here) for this already. This one is in C. Reason why I bothered is because next feature uses a hook in the same location, so we'd have a conflict there.

Spoiler:

Moving the level cap:

Spoiler:

Surprisingly people weren't as enthusiastic about this one as I thought. I moved the level cap four/five months ago I think, although it had few oddities and imperfections. :P This time I changed a bit the way I made it and used look-up tables instead of calculating values at run-time. Also made it a bit nicer to display 4-digit stats(sadly EM's stat display wasn't made in mind with such large stats, Fire Red's one is much better for that). I tested it and should work all fine except for displaying 4-digit HP in battle which I'm yet to figure out.
You can choose the max level for pokemon, so theoretically instead of upping the cap you could bring it down to something like 50.
Screenies:

Spoiler:

This Blissey is legit I swear

Pokéball Expansion:

Spoiler:

Every Pokéball from Gen 4 onwards have been implemented. This means Kurt's Apricorn Balls have all been included with the correct effects, and the new Pokéball from Gen 7, the Beast Ball.
You can enable this by going into the build.py file. There should be a label called
"BallsExpansion" and "FirstNewBallID". To enable the ball expansion, simply change "False" to "True".
The second label is where the first new ball's index will be. Make sure you choose a suitable place
with several free indexes, as all the new balls will be given indexes here and afterwards.

HUGE credits for: Tetra, AngryBird, Kabby and Bela who made all the sprites.
Also thanks for Tetra who was kind enough to send me all the images in a hex format.

Screenies:

Spoiler:

Menu options toggle:

Spoiler:

The options in the menu, such as Bag, Save, Exit and more can now be toggled with the use of a flag! Once again, in the build.py file, there should be several labels such as
"FlagPokedex", "FlagBag", and "FlagTrainerCard" (There should be a flag for every menu option).
You can change these to any free unused flags to avoid problems later on.

Screenies:

Spoiler:

Fire Red style fishing:

Spoiler:

You can now enable Fire Red style fishing instead of the R/S/E style fishing. This means there will be no biting, but either
an encounter or a fail. This can be enabled/disabled in the build.py file under the label "FireRedFishing", by setting it to
"True" or "False".

Chain fishing:

Spoiler:

From 6th Gen, chain fishing has been implemented. If you hook a fish several times in a row, the shiny rate will increase.
To enable this, go to the build.py, and look for the label "Chain Fishing". Change "False" to "True" to enable this feature.

Shiny Charm:

Spoiler:

Introduced in 5th Gen, the Shiny Charm is an item that increases shiny odds for every encounter by a specific amount.
This effect can be assigned to an item ID, for which you are using for the Shiny Charm. To set the item ID, go to
build.py, and look for the label "ShinyCharm". Set to what item ID you want it to be. (0x1 would be how you'd write 1 in hex, and
if you want to write the item ID in decimal, don't use the 0x prefix.)

Hall of Fame Expanded Pokémon Fix:

Spoiler:

Expanded Pokémon from the Poké Expansion don't display properly when viewed in the Hall of Fame. A fix has been implemented.
To apply this fix, go to build.py, and look for the "HallofFameFix" label. Change it to "True" if you want to enable it, and "False"
for disabling it. (If you aren't using the expansion).

New Specials:

Spoiler:

A bunch of new specials has been added to make it easier for romhackers to do things that are not possible just by using scripting commands.
Here's the full list of them along with descriptions and script examples.

Installation:

Spoiler:

- Download devkitpro from here.
Follow the instructions.
(Note: you can only install devkitARM)

- Download the latest version of python(3.5).
After downloading and before proceeding to install make sure that the 'add to path' checkbox is ticked, otherwise you'll have to add the python path in the environment variables manually.

- Download the master folder from the github page here.
(click 'Clone or Download', then 'Download Zip')

- Place your rom it the main(master) folder.

- Go into scripts folder and open 'build.py' with a text editor and modify it accordingly to your will.
Graphical representation of what you're to do.
You can apply any features you want, they're all compatible with each other and work on their own.

- Run the cmd.exe in the main folder.
You can do this by typing 'cmd' and hitting enter in the url address or selecting 'run command prompt from here' from right clciking on empty space while holding the shift key.

- In command prompt window, type 'python scripts//build.py' and press enter.
A new gba file will appear named as test.gba along with 'offsets.ini' that provides addresses of everything that was built.

I'm open to any ideas, so if there's something you'd like to see in EM, tell.

Hey Dizzy, I used your previous Emerald patch that raises the max level to 255 but saw that it may not display a 4 digit stats correctly. If I reuse the new one on my already applied mod, would it work properly still?

 

[LCCoolJ95]

Very awesome my man, but why didn't you make it into an optional feature in the upgraded engine, like what you did with Capture EXP? And will this work together with the engine?

 

[DizzyEgg]

Hey Dizzy, I used your previous Emerald patch that raises the max level to 255 but saw that it may not display a 4 digit stats correctly. If I reuse the new one on my already applied mod, would it work properly still?

There may be problems with hooks. Damn, I just deleted the repository so I may not remember all the hooks locations but if you still have it here's what you do. Check hooks file, go into every offset there is in a hex editor and replace bytes there with what was in the original rom.
If you'll have problems, send me your rom via PM and I'll release a patch fix for it.

Very awesome my man, but why didn't you make it into an optional feature in the upgraded engine, like what you did with Capture EXP? And will this work together with the engine?

Because Battle Engine is just that, a battle engine. I simply don't want to mix everything into one project. And Capture Exp is related to battles. :P
All my works are compatible with each other.

 

[Froosty]

wanted to ask you one thing,
is the coloured stats hook conflicting with the hook of level cap or some else feature ???

 

[DizzyEgg]

wanted to ask you one thing,
is the coloured stats hook conflicting with the hook of level cap or some else feature ???

Yeah, they both use the same hook location.

 

[Froosty]

Hey just wanted to know how is your work of hidden ability going on???

 

[Jeesh]

All(I think) new evo methods have been implemented. I'll try to provide inis for them later(or if could someone else do it I'd be grateful ).

Heeeey,
I have a problem with the new evos.
When I try to evolve using a move, after the mon learns it from level up in battle, as the screen transitions to overworld it just stops and freezes on a black screen. Also, when I try to use an item on a specific gender mon, it says it won't have any effect. Levels above 100 and the nature colored boosts are operational, but NONE of the new evolutions are working. Is there something I did wrong?

Whoopsie! My bad, I forgot to update the linker file with given offset. The freezing was caused because the compiler assumed everything was being built at 0xF00000 even though the location may have differed.
I fixed it now, so re-download and it should work. :)

Oh, great! Thanks :D

EDIT: Actually, now theres a syntax error when I run the build script with a file in the devkit folder.

This thing:

Says it has a problem with line 30 and/or 32 in the linker.ld file, which is just a "}."

EDIT: I tried deleting and editing some charaters in the lines with errors. After a few tries, it made a rom. But the evolutions didn't work. They just went straight to overworld. This may have been made even worse, cuz I didn't have this error with the old one.

 

[Thorec_G_A]

You are amazing DizzyEgg! These features are great. I'm sure I'll use them. Thank you for contributing to Pokemon Emerald hacking :)

Seems to be a problem with newlines. Check it out now.

[DizzyEgg]

Have this glitch when leveling up...empty spots in party level up:

Tell what you applied that caused it. If you don't know, apply one thing after the other and see when the bug shows up.

 

[Jeesh]

It still didn't work.
Like, it doesn't even look implemented.
To be specific, everything's operating. But the evolutions (I'm mainly testing the "Know Move" evolution type) are not. When I set it up in PGE, and have the mon learn the move on level up, it doesn't evolve when it LEARNS the move, and it doesn't evolve when it LEVELS UP knowing the move. Again, everything else works, but evolutions don't.

Apparently the engine is causing it. Do you want me to send you the ROM?

Everything else works fine, right?
Did you expand the evo slots from 5 to 8?

 

[Jeesh]

Yes. Is that a problem?
I hope not, I want 8 evos.
