How to extract png from dat file?

[horseshoecrab]

hi everyone, these past couple days i have been trying to rip a lot of the sprites from youkai watch puni puni, a lot of them seem to be stored in .dat files. i opened one up in notepad++ and it had a png file name in it so i assume that's what's stored in it but i have no idea how to get to it. is there a program or something that could get them out for me? i tried to search past threads but everything i found either went way over my head or i tried it and it didn't work. thanks! :)

i've also uploaded one of them here in case anyone wants to mess with it, if the link doesn't work please let me know
