Hacking Metal Gear Acid 2, need help with file formats and extracting card images.

[Parallax_Odyssey]

Hi, im here asking for help to understand a little bit what the file formats are (i know what some of them are but ill ask anyways) and also what are programs that can help me read this files, as you can see the Acid or "Ac!d" series was never really covered by anyone and i think it did a great work at being the best homage to Kojima and the his work in the past+ i dont see anyone doing anything for this game (if there is let me know please.

The folowing files that i dont know what they are:

• .a3p
• .prx
• .pmf
• .psq
• _zar(it doesnt technically have an extension)
• .sfo

If you know how to read this files please let me know, im using UMDGEN since theres no other way(i know of) of seeing the files or if theres a way of fnding more files let me know, thanks to anyone and if everything goes well ill upload the cards for everyone to print in the optimal resolition.
