I made DumpAll, but it may not be usable.
When using this, write out the animation as text, export it in java serial form of FEEditorAdv, and make gif animation.
I have not fully understood java Serialize yet.
There is an unknown byte in the type information.
When outputting in FEEditorAdv format, FEBuilderGBA packs specific data hard-coded into its unknown type information.
Since FEBuilderGBA does not use this type information, you can import whatever value is written.
However, FEEditorAdv refers to this value in java deserialization.
And, it does not work with an appropriate value.
FEEditorAdv asks for a perfect value.
Therefore, even if FEBuilderGBA can read the Java serialization format of FEEditorAdv outputted by FEEditorAdv,
FEEditorAdv may not be able to read the Java serialization format output by FEBuilderGBA.
This is due to an unknown type information byte.
Therefore, it is dangerous to use the java serialization format output by FEBuilderGBA for data you want to widely publish.
Of course, if it is txt format it is compatible.
Since there is little to make java serialized type information in other languages(C#), there is no document.
So, this mystery has not been elucidated yet.
