You need lyn.exe.
This is also written in the explanation of the patch.

MMB is written using lyn.
Therefore, it is necessary to set lyn so that it can be called from EA.

Please copy lyn.exe to EA’s Tools directory.


I have created the “DismountEx” Patch.
Please update FEBuilderGBA.

You can ride a horse with the Rade and Exit command.
For riding units, please create a setting.

By default, Eirika(Lord), Seth, Neimi(Archer) can ride a horse.

In addition, you can forcibly put it on a horse with an event order, and you can lower it.

However, using this function affects promotion, so it would be better to target only promotion unit.
Or you need to adjust the mechanism of promotion.

For compatibility, when selecting Archer to ride on the ballista, the ballista is given priority.
First of all, please try after back up.


Please forgive me for asking this silly question. I didn’t find a document that could be executed.(lyn.exe)




Are you using the latest version of EventAssmbler?

In older versions, you can not use the symOutput option.


Thank you very much for your guidance. My problem has been solved successfully.


Hello, I’m having a glitch here, I cannot change the maps of the prologue and chapter 11 in hector and eliwood mode, They only accept one custom map I made, but if I change it the screen goes black, and not opening black, it stays black even with the OOBB command in the Events.
Also my class table is going beyond FF and I don’t know why?
Here is my report:


I am not familiar with FE7.

First of all, I do not know if there is a patch that can fix problems when expanding classes with FE 7.

About the chapter.
I think the “start event” of the prologue is broken.
The address of “start event” does not point to an event.
It referring to an unknown byte.

Have you done anything special to skip lyn edition?

I think that it is better for you to redo this project with FE 8.


On a separate map editor, they have the ability to generate maps automatically, such as mountains and palaces. They can produce rough outlines that can be used only with modifications. FEB can’t, especially mountains. It makes me dizzy. You might consider introducing this feature.


Please use FEMapCreator.

Export the file in Map format and open the file with FEMapCreator.
Import the map format after editing.

I had created automatic generation a long time ago, but I did not get the expected performance.
It is best to use FEMapCreator’s automatic generation.


I have a question about the Affin and weapon level icons, when I look at them in FEBuilber, they look off color, if I import new icons over them, will they be off color in game?


Weapon level icons and Affin icons are drawn using a special palette.
This palette is in the system icon.

The palette of Weapon level icons and Affin icons is common.(maybe)


It seems to have missed a transfer prop. His code should be C1.

Upgrade the props


Hi , is there a way to change the value from skills like activation rate , damages …etc ? I feel like it’s “a bit” to overpower .


Can use Nergal Dark aura in FE8 on this program ?


I think there is a problem with the Stat Boost option in both FE7 and FE8 in the newest version of FEBuilder.
I don’t know why :thinking:


please send report 7z.

I do not need an image.
I need data that can actually be reproduced.


About skills, please contact the SkillSystems.

The skill of FEBuilderGBA is the July version.
It is a slightly old version.

We are currently planning this update.


It does not exist in FE8U.
Although it remains in FE8J, it disappears in FE8U.

Besides that, animations that are not used, such as Ekkesax’s shock wave effect, remain in FE8J, but have disappeared in FE8U.
Since FE8U was released after FE8J, it seems that it deleted the animation which FE8 did not use.

Please use other magic animation using magic expansion patch.
