Our CS beta plays perfectly, so far, on a Windows 8 phone using SNES8x. However, the SNES emulator - unlike an NES emulator I have loaded on the same phone - apparently does not capture screen shots. So, I took some samples with a regular digital camera. The game screens are a bit fuzzy captured this way; however, they appear perfectly brilliant viewing the actual phone display.
Heh, who would have thought in the 1990's that we would be playing our own translated Super Nintendo Japanese RPGs on a dad-gum telephone someday!?
Edit: Okay, the controls are very unresponsive for me in cave-building, room cleaning, and especially fighting. First, I can't remap the buttons. For many years I have made the A button closest to me and the B button to its right. I've also switched X and Y so that all of the buttons proceed from left to right in alphabetical order. This is the way my head works and my fingers respond.
Since fighting relies on executing a combination of buttons, I don't find that a touch pad can replicate actual physical three-dimensional buttons. My conclusion is that virtual buttons on phone emulators are not very well suited for action games. The solution for me would to convert a USB game pad to a mini-USB adapter, plug it into the phone port, and somehow be able to drive it, map it, and make it work with a downloaded emulator application.
I've played Mystic Ark and DoaE-II successfully on the phone, and I find that these virtual buttons are adequate for turn-based RPGs.
