I want to rip SM5 and Conception 1 sprites

[Arcafa]

I was looking for a way to rip these games's sprites and I can't find any tool to help me to it. Does anyone have some idea to help?
Note: the conception file is a prx file and the summon night file is a dat file.

Sample file from Conception 1:
