The game was released for the PS2 and NGC.
please I can't find it.

Not that I know of. In fact, the vast majority of the music is from the original games as all 8 up to that point were on the disc as well as 2 other games. So you probably can seek those out elsewhere.

Thank, man.
I was just looking for the arrange ver. tracks in the game.
for example this one. https://www.youtube.com/watch?v=cKAWlZGe18M

Many of the MegaMan Anniversary tracks are available in ROCKCAN Sound E Can (Rockman 25th Anniversary). The Youtube link shared above, the track used is track 26 of the third disc of the soundtrack album.
