perhaps the majority here ignores this game, I've been researching and noticed that its development was stopped, which is a shame as it is a lightweight and extremely enjoyable gameplay game. It is a great alternative for weak computers.
Guitar Zero 2:
Multiplayer: COOPERATIVE, FACE-OFF, PRO FACE-OFF
Support for OGG files (Song, Guitar)
Supports MIDI and CHART
HyperSpeed
HO/PO Similar to GH3
Whammy bar
Starpower
Compatible with Keyboard and GuitarControler
Setting keys and alternate keys
Some prints
---Considerations---
-To run this game you just need install Microsoft XNA Framework
-To add songs, just copy and paste the file SONGS of your FOF in the GZ2 file
At last, the game is the resolution 1514x682 (No Fullscreen), you can change the resolution by editing the "Config.xml" file. But I do not recommend because it will change the shape of the fretboard. This resolution makes the fretboard seems like GH2 / GH3.
