I never tried that rom , but I attached a few screen shots from cosmicdans miui rom...
...with cosmicdans miui you can have all the best parts of the xperia play with any kindve look and feel that you want it plays most games very well and touhcpads work .. its a win win IMO..
Does OnLive work with cosmicdans miui?
I installed XDARK ICS today and now the hardware buttons don't work but PERVERSELY the touchpads now work in it...it was the other way around in stock.
I hate the touchpads to be honest, I cannot use them properly myself so I'd be interested in getting recommendations for ICS roms that work 100% with the hardware buttons...
