Few days ago, i found myself with the "Final Fantasy X-2" and "Kingdom Hearts 2". Both games have the excellent BGM, but i wondering if those 2 games sound could be made from internal PS2 Soundchip ? Because i haven't heard about PS2 Soundchip ever, but any idea ?
Google "Highly Experimental" and "PSF2 file format". That's a plugin which emulates the PS1 and PS2 sound CPU and sound engine. The player can be Winamp, for example. Final Fantasy X, Final Fantasy X-2, Final Fantasy XI, Final Fantasy XII, Kingdom Hearts, Kingdom Hearts2 and a few other games (un)surprisingly use the same sound engine and midi/sound sample data format.
