Persona 2 Eternal Punishment PS1 (.BIN)

Post by cristyro »

Can anyone please help me with extracting Persona 2 PS1 .BIN files? I have tried many times with QuickBMS but I always get errors, due to my lack of knowledge using it properly.

These sample files appear to have readable text using hex editors, most commonly near the end of the file: https://www.dropbox.com/s/l8ix9pno6tk08 ... es.7z?dl=1
The hex sequence 01 11 36 11 20 appears to be a new line trigger ( \n or {0A} ) as far as I can see.
Later Persona games use BMD, BF, PM1 and MSG file formats for text, it's pretty much the Atlus standard, but I've no idea about this game.

These files have the magic identifiers pqes/pbav inside them so I guess they are/contain seq files that have audio in them (pgconv is able to find midi files inside and play them): https://www.dropbox.com/s/34pwgplo9ngdo ... es.7z?dl=1

This file has character portrait images inside (I was able to extract 266 png files from it with jpsxdec): https://www.dropbox.com/s/e0v67mjmkshkk ... le.7z?dl=1
However, I don't recall how I got it, it might've been altered by an incorrect extraction with quickbms, so if there are issues with it, that's probably why.

When I tried to extract F0000.bin with quickbms, I got an incorrectly extracted, empty file with this filename: mi\src\m_mvivw.c , although I'm not sure if it's really inside the archive or the script was just wrong. This is a much smaller file. Here it is: https://www.dropbox.com/s/l7chjh2jw5cc75j/F0000.7z?dl=1

There might be .dat or .mde files inside, but I was unable to extract any. If you need more sample files, I can provide them.

Thank you for taking the time to read this!

There is no common format in these BIN files, each one is just data.
