I am going to tell you hot to skip the compatibility error on htc explorer..
1) Rooted Pico
2) ES file explorer
Open es file explorer and then press the menu button.. the click on root explorer.. then grant superuser permissions.. after that go to the internel memory and go to the system folder.. then you can see a file build.prop.. open it and find these lines and edit them like this.
ro.product.model=xperia mini pro
after editing reboot your pico... now you able to play gameloft hd games.. This will work on any rom.. But i suggest you to flash gamersab or cm9.build 14..
