Psikyo arcade shmups games Steam/Switch (.bin file)

[Mark]

Recently, there are 3 Psikyo arcade games published on Steam(and more to come!), so I take a look. All of the games can be easy to translate since the text file can be edited pretty straightforward, but not the UI textures, they are contained in a .bin file which has no file name indicated in the hex editor, only through executable can you see the file name. How can I extract and reimport the textures?
File name in Steam executable:


File name in Switch version:


I will upload both Steam and Switch version of GUNBIRD .bin file.

I guess BIN is just a container and the table of information is located in another file.
Long story short, run offzip -a on them.
