1. I have just bought FpseCE on the android market. Is that version the supporter version?
2. How the heck do I change my skin to that blue high tech looking one I see one youtube?
1. The supporter version was always referred to with the WinMo version. There was a free, and a donate version, you were a supporter if you donated. To gain special features like save-state. But with Android, there is no free version. So yes you can call it a supporter version. And you have bought Fpse for Android on the Market, not FpseCE.
2. Download the skin you want. Put it in a file somewhere on your phone. Open fpse go to SETTINGS/INPUT/TOUCHSCREEN/OVERLAY PAD/EXTERNAL. This will bring up a file browser, find your new skin folder, open it. Choose the pad.ini file you'll see there.
