Hi guys , i am having some issues with Rom Hacking. Recently i got into the files of Mario Sports Supestars (CIA) and got the ROMFS folder. The game is enterily compressed and 99% of the files are compresed in various .dat files. My question is , does anybody know how to open these files to extract the contents? I was looking forward to possibly mod this game , specifically the voices and music. Here are some screenshots of the ROMFS I mainly am looking for the sounds of this game , which i am guessing are inside the na folder. Please if anybody knows how to start solving this i would appreciate it so much , i have done some research but i'm not having any luck solving this on my own.
