Examples:
in Persona 5's tittlle.pak
p5tittlle_01.spd > Textures
Texture 00 [ps3_tittle_01] is viewable in the program
Texture 01 [ps3_tittle_02] is not viewable, but can be exported as DDS and can be viewable in another program (like photoshop)
in Persona 5's ps3.cpk and ps4.cpk
font > chat > chat.pac > chat.spd > Textures
Texture 00 [chat] does not display the full texture. When exported as PNG, what you see is what is exported, however exporting as DDS reveals there is actually more to the file than there is viewable in Amicitia.
