[PSP Puyo Puyo 20th Anniversary] Extraction of GAME.DAT (via an executable)

Post by Shiruba »

I wanted to extract the PSP version of Puyo Puyo 20th Anniversary. In this game everything is in a GAME.DAT file.
Hopefully somebody already wrote an application which allows the extraction of the file. I managed to make it work for the Wii version but for the PSP version I didn't manage to do it.

It seems to extract the PSP GAME.DAT you need to have an executable named "NPJH50492.BIN" (with NPJH50492 being the game ID) but I don't understand what this file represents nor how to get it. I have extracted the iso with UMD Gen but didn't found it. Here are the files that are in the iso, maybe the "NPJH50492.BIN" is hidden in one of the files or something like that.

If somebody knows how to get an executable from a PSP game, is it possible to know how?

It's just a decrypted EBOOT.PBP, you can decrypt it with DecEboot, just drag and drop the EBOOT then rename it to "NPJH50492.BIN" or leave it as is then use it with the tool.
