Well I dunno what kind of connection you have...

If it's a big deal to download 1.2gb that the complete pack takes, and if you simply only want to patch the version of the game that you've already downloaded (with arcs 1-4), then:

1. Get the 1-4 music pack compilation (non-PS2)

2. Get the sound patch v2, because the version of the game that you downloaded from that mediafire link might not be fully updated

3. Download the font patch and install the font file in it (drag it into the Windows Fonts folder if necessary)

The game you have should already have the PS2 graphic patch in it.
