“Guitarway to Heaven Riffs” by RRS dev team helps you learn to play riffs on guitar.

Release notes:

Another homebrew from the RRS dev team, this is our first application we made. Build on the PSPRevolution Engine, this application learns you to play various riffs on guitar. The program displays the tab and plays the song to play along.
