My current list. All tests were made on JXD 1.1.4 official firmware.
So far, I've tested only small number of games, unfortunately. I should blame wonderful
Meltdown from Bulkypix, I spent dozens of hours playing it for two last weeks (if you didn't tried it, don't hesitate - it's free on Google Play, 3D hi-tech isometrical shooter with online cooperative multiplayer; runs perfect on S7800b!).
If you want to help me with this list, please tell what games works for you. Also don't feel shy to recommend some great ones to community here. Every contribution will be greatly appreciated!
