Side Quest Menu [FR]

This hack converts the PC item storage menu into a side quest menu, or task list, etc.

Here is the repository, the compilation instructions are included in the readme. You will need to define your own parameters/ram in src/headers/defs.asm and create your own tables of string pointers for all of the quest names, descriptions, item images, and quest details. I kept the item image part to allow hackers to include items that might be symbolic of their quest, eg. a scroll or key or pokeball.

To use in a script (XSE)

Code:

writebytetooffset 0x1 <your questflag ram in src/headers/defs.asm> fadescreen 0x1 callasm 0x80EBCD9 waitstate

Here is a slightly outdated example GIF (it is just missing the item images in the box), but it gets the point across.

Enjoy! And please let me know of any bugs.

Nice work but you may wanna remove .exe and dll files as not everyone uses Windows.

Yes, you are allowed to put routines for Ruby as well.

[FR] Multi-directional jump tiles
This is an expanded-upon version of Invert's routine on the Wahack forums (https://wahackforo.com/t-40642/fr-asm-salto-en-cualquier-direccion) So credit goes to them for the original.
Made this for the purpose of creating a multiple-height jumping puzzle which was something Invert's routine was lacking, so thought I might as well share it.

Code:

.thumb

.global AnyDirectionJumptile
.equ rom, 0x08000001
.equ offset, 0xXXXXXX

/*
Behavior bytes:
0x7F = able to jump in any direction over tile (only on height 0x0 & 0x10)
0x7E = able to jump up and down over tile
0x7D = able to jump left and right over tile
*/

Evolution Moves [FR]

Adds the feature of learning moves when you evolve, regardless of the level. Currently, only compatable if you have expanded your moves above 511 (jambo learnsets). May make it compatable with old learnsets if there is a desire.

Here is the repository. Update config.ini with your learnset table location and a free ram address byte (does not need to be in the save block hack. Example free space starts at 0203e000 if you've removed the help system, I believe)

I've only done prelimenary testing, so there may be bugs.

Hello,

I'm having a hard time understanding an aspect of your system, mainly the flags. So if you have 256 quests (the max, still kinda a small number), does that mean you need 512 flags? Consecutive flags, at that? So quest #1 would be flag 0x200, and that would go all the 0x2FF, leaving me with literally no other safe flags for the entire game, or to complete the other 256 flags eaten by the routine? Looks like I might have to dabble in expanding safe flags, unless I'm missing something obvious here.

Edit: Couldn't I just set the "flag" offsets to some unused RAM? Probably not, since it wouldn't be covered by the save block. And how do I convert the flag number to a RAM location?

Thanks, hjk321

Nice routine though!

Nice routine though!

I kept the instructions somewhat vague to allow different users to utilize the system the way they like, though you're right that I could have been a bit more verbose.

The system is set up so that you will need two flags for each quest: one to 'activate' the quest, which just means you have unlocked it and the quest name will show up in the menu and you can activate it and whatnot. The second will indicate that the quest is completed, in which case the 'Done' text will appear next to the quest name.

It is currently written so that the activation flags (to show the quest names) are in order, and the completion flags are also in order, but can start from a different initial flag. This was done to prevent the use of two separate tables, but can easily be changed.

256 quests seems like a pretty high number of quests for a rom hack though. And that is not necessarily the limit, the active quest ram can easily be expanded to a halfword value.

I would recommend expanding the safe number of flags with JPANs save block hack; this way you can unlock thousands more safe flags and this system won't be as limiting.

I'm not entirely sure why you would want to use RAM instead of flags; that would end up just taking up much more space unless you edit the routine to check for specific bits in the ram, which is then the same functionality as a flag.

I hope this helps.

Literally everything about your routine is great... except every quest is ???????? whether the flags are set or not! in the defs file I've tried RAM pointers (0x0203C001) I've tried repointed flag numbers (0x909) and I've tried raw flag numbers (0x2109) and no matter what the quests do not show up!

As an experiment I have 15 quests and I set some flags At the index. Index starts at 0203C001, have also tried 0x909 and 0x2109 in defs.asm. Here is proof I have flags set in that area...

and yet all 15 quests are unshowable. What am I doing wrong?

I only made minor edits to some text variables, as well as linking to external tables rather than making a table in the actual asm. I didn't edit anything significant.

Can you share your code so I can better understand what you are trying to do? Let's do this via discord or personal message to keep this thread clean. :)

Hi ASMaties! I'm new to hacking and I'm not sure how to go about this? would it be okay if I requested some help modifying the way EV-increasing items (HP Up, Protein, Iron, etc.) work in Emerald?

The default behaviour adds +10 EVs, but it has no effect when the EV is >=100. I want to remove that restriction so you can keep using EV items and max out an EV at 252, allowing players to EV train quickly and painlessly.

Any help would be much appreciated!

Evolution Moves [FR]

I found a bug in this code where a pokemon learning a move from any other way would be asked to learn moves it already knows and will be asked to learn a move even when their movesets are not full.

I rewrote the moveset loop by just calling a custom function rather than editing the main learn_move function at 0803ea88, and it appears to work fine.

Spoiler:

If you implemented the original routines, be sure to replace the bytes at 3eaa4.

Ok, I know know your routine does some mistakes with the registers. If you want a working soulution, also shorter than this, DM me.

Consider just sharing it here directly for everyone's benefit. Thank you.

[FR] Fully Flag-Dependent Start Menu

It's nothing fancy, but this code expands on FBI's routine to swap between start menus, shown here. It also keeps the safari zone start menu intact.

Every single start menu option (except Exit) is flag-dependent, so you can add or remove start menu options with simple flag setting/clearing.

Spoiler:

for example, with the current definitions, setting flags 0x251, 0x253 would make the start menu be composed of only "Pokemon","[player]", and "Exit".

Potions go into the Key Item slot when I use this? What am I doing wrong?

You need to delete your save file and start a new game. Or, implement this routine by Sagiri, and then you can just start a new game normally. If you used the saveblock routine from this post and you do implement Sagiri's routine, make sure that you change the first line in constants.s (from Sagiri's routine) to

Code:

.definelabel jpan_block, 0x0203C100

as that is where I started the saveblock in JPAN's routine.

Zeturic · Nov 9, 2018

Since it got mentioned above, I figured I'd post this here.

It's been tweaked slightly so that it only uses armips, rather than the build system I use for my C stuff. All it really did for it was find free space automatically, and, while that's kind of useful, I feel it unnecessarily overcomplicated it.

In any case:

Clear JPAN Save Block During New Game [FR]

Fixes an oddity with JPAN's Save Block Recycle where the saved memory doesn't get zeroed upon starting a new game. Instead, it'll retain whatever it happened to be in the previous save file.

To be clear, this does not actually include JPAN's Save Block Recycle itself.

Unhidden Power [FR]

This routine makes the game calculate and display the actual type of Hidden Power in battle and in status screens. If, for example, a Pokémon's Hidden Power type is Water, it will display as a Water-type move, just like Surf or any other Water-type move.

Note that this only calculates and displays the type, not the base power.

Evolve by Leveling Up While Holding An Item [FR]

Adds evolution methods to allow Pokémon to evolve by leveling up while holding a particular item. Also included are day and night variations for use with Happiny, Gligar, and Sneasel.

Other implementations of this evolution method have a subtle bug - they remove the item even if the player hits B to cancel the evolution. This avoids that.

Summary Screen Wraps Around [FR]

Allows you to hit Up on the summary screen of the first Pokémon in the party to move to the last Pokémon in your party, and likewise hit Down on the last to move to the first. This change originated in XY and has become standard in all later games.
