All for FE8U.
Some minor modifications suitable for porting to other people’s games may be shown here. Mainly write in C.
Repo in github see here (which is just working-in-process)
Decomp-based C-Hack Template
This is a simple example of building the Buildfile based on Proj.FE8U-Decomp outputs (or say c-hacks, CHAX).
The Wizardry folder includes some functions based on decomp, you can directly copy the decompiled function into it and modify it again.
The repo’s readme documentation details how to compile. I think this may be a beginner-friendly tutorial-type template.
I also use this template to test some new functions, so I recommend it to you.
New Decomp-based C-Hack Template
Battle Forcast Hit-Counts Hack
BkSel Expansion
This hack enables you to get any number of hit counts to show on Battle-Forcast window.
Just include BkSelExpansion.event and you will make it.
Unit Status Rework
Expand Unit Status to 63 index
In vanilla, unit status (buff & debuffs) use a u8 byte at Unit Struct +0x30 , 4 bits for status-index, 4 bits for status-duration. In this work, we have expanded unit status index to 6 bits, which can support up to 63 different states simultaneously. Meanwhile, through a series of modifications, we successfully used the remaining 2 bits to make the status last for up to 4 turns.
Null BWL
Remove the total BWL Table entry
BWL Table, or Battle & Win & Lose table, a ram-space as large as 0x460 size that can be saved and loaded in save & suspand data.
The data has no meaning to the game experience, but it can provide a 0x460 saveable data for hackers as a free-ram-space.
Previously @StanH has worked Brif-Bwl in Skills-Lite, in this work, we completely shielded this area from all read and write operations except save-data operations, making it a free-ram-space that can store data freely.

Hack on Skill Anime Effect
Reset the Bg config to null the semi-transparency effect.

Costum Game Intro Gfx
H&S Screen Rework
DIY on H&S Screen. You could just include GameStartScreen.event and get it. For your own gfx, replace the file Data/GameIntro.4bpp.lz with a LZ77 compressed Png2Dmp file.

Promotion List Expansion
Promotion Rework
Reworked on promotin routinue to allow diy on promotion list. Now you can freely decide the promotion list based on character index, class index and item index. Since this patch does not involve the item system rework, if you want to use non-promotion items to promote characters, you will also need other patches such as IER.
Just include PromotionRework.event and then you will get it. For custom usage, define your own usr-function const u8 *GetUnitPromoList(u8 charId, u8 classId, u8 itemId), I have made an example.
ClassChg (Promotion) Expansion Rework
Promotion Expansion Rework
Download here
a rework of Old promotion expansion, enable unit promote to no more than 6 classes.
1. Custom Usage
1.1. Vanilla table
Vanilla table of 2 selectable classes has been retained. You can also config on old table to diy branched promotion classes.
1.2. Expansion
At the same time, there are two list for promotion expansion:
-
gPromoJidLutExpa
A0x100 * 4linear table according to class index.
You can config 4 additional class to promote.You can also config this table by FEBuilder’s patch, ./patches/PATCH_ClassChgExpandList.txt -
gClassChgExpaMods
A table for promotion with higher degrees of freedom. A unit can promote toClassChgExpaMod::jid_promoif:
- The configed class index is matched
- The configed character index is matched
- The configed item is used for promotion
- The configed event flag is set
You can config this table by FEBuilder’s patch, ./patches/PATCH_ClassChgExpandModulearList.txt
1.3. Trainees
As for auto-promotion for trainee class, there is also a reworked table for configuration. gpTraineesRe , with two element jid and level .
You can also config this table by FEBuilder’s patch, ./patches/PATCH_ClassChgExpandTrainee.txt
Custom Build
If you want to modify on source code, please refer to CHAX template, note that the C-Lib use the ver.2023.07.31.
You can also write your own jid-getter function and add the function to the list gGetClasschgListFuncs.
/**
* r0: unit struct
* r1: protion item
* r2: out buffer
* r3: length of the out-buffer, DO NOT overflow!
*
* return: amount of the classes to promote
*/
typedef int (* GetClasschgListFunc_t)(struct Unit * unit, u16 item, u8 * out, int len);
extern const GetClasschgListFunc_t gGetClasschgListFuncs[];
Note that this patch has been embedded to the latest version of SkillSystem, you can directly use the FEB patches without installing for skillsys users.
Map Anime Effect: Gravity
A Map Anime Effect
A DIY map anime, just like Debuff-Status-Clear-Routine.
Just include MapAnimesInstaller.event, then call for function void StartMapAnim_Gravity(struct Unit* unit, ProcPtr proc), then it will start a child blocking proc to show anime effect.
Due to the default of the program, the target character exists in the current screen, so there is no effect of moving the camera. If not, you can either move the camera over before calling the function, or delete the comment on line 41 in Gravity/Gravity.c
Replace “a” or “an” to space
Function: PrependArticleToString rework
For now, replace “a” patch is just delete the character, this patch has rewrite function void PrependArticleToString(char *str, const char *insert_str, s8 c) so that we can replace “a” to a space.
Just include “RemoveA.lyn.event” and then you will make it. Don’t forget define your own FreeSpace since this is just a c-generated file.
Change Weapon During Target-Select
TargetSelect Proc Rework
A interesting rework on SelectTargetProc so that we can change weapon during target-selection.
Now Up & Down botton will change the target, meanwhile Left & Right button could make you change another weapon to attack. If you don’t have any other weapons to attack current target, then the Left & Right will function as vanilla to try change target.
- Note
This patch does not considering Weapon-Range Rework! If you have already worked on Weapon Range such as apply ProperRangeGetter or WeaponRangeRework, you need rewrite the following functions in the fileSrc/NewTargetSelect.c: IsItemCoveringRange and GetItemReachBits.
Unit Debuff Banim Flashing Rework
DIY your own flashing effect for debuff
A patch that allows you to customize the debuff flashing effect on unit during battle.
Download Here
Usage:
Include file EfxStatusUnitRework.event and define your own debuff flashing effect in EfxUnitDebuffPalConfigTable, which you may define the flash R/G/B color and the flashing speed.
The R/G/B effect is recommended ranging from 0 to 0x10, the higher value may result in a more pronounced flashing.
The speed range from 0 to 3, in which 0 will not change the color, 1 is the slow speed, 2 is the vanilla, and 3 may flash fast.
This patch is not conflict to any existing patch since the unit debuff index is not directly caught from unit struct, so don’t worry.
