I had most of the problems described above. Keys not recognized, sticky / lagging strum bar...This article solved all my problems:
http://www.althack.com/2007....trollerMy setup:
- HP Pavilion Laptop
- FretsOnFire1.1.324 (googled it) + RF mod + "New Notes and Keys" mod + "All in one" mod's "Flame 1" background set to static (GH2 practice room). I disabled "Flame 2" via RF mod settings. - Sony PS2 GH2 Gibson SG controller
- Red Octane USB adapter + driver from the website (see post 7 on page 1)
- Running JoyKey (see post 1 to download).
The article makes a few important points:
1. You need to extract the author's JoyKey configuration into your JoyKey folder.
2. Have JoyKey running the author's config (FretsonFire-Althack.com) before you open FoF.
It worked like a champ. No laggy fret bar and the menu navigation works just like GH2 (up on strum bar=up, down=down).
I had set the controls using a borrowed XBox360 controller and it was hopelessly messed up when I tried to configure my PS2 controller. I just pasted the original key.dae and key.pyd files and started over with a clean slate.
Hope this helps.
