That’s impossible.
The event instructions of FE 7 and FE 8 are completely different.
You can export it in EA format, but you need to manually convert it for FE8.
The biggest difference between FE7 and FE8’s event instruction is that there is a memory slot.
The way to branch events is quite different.
Unit setting etc are also different between FE 7 and FE 8.
For example, there is one Promotion on FE 7, but there are multiple Promotions on FE 8.
Therefore, the data structure is different.
Unit Placer also has a different format.
In FE 8, it is possible to set the movement route of multiple units, but only FE 7.
Also, how to set drop items is different.
I think that it is faster to create it from scratch than to correct these differences manually.
