I finally got my RS-97 from Amazon and had some time to test it. Sadly I'm not very impressed
While the case itself is well made, the buttons are waaay to wobbly. I really don't know if I have a different device that you all. The shoulder buttons feel like they fall off any time
And then the screen. As mentioned here, it has a 320x480 resolution. But wait, hasn't the the screen a 4:3 aspect ratio? It has! That means the screen is vertically shrunk and that's why the menu looks so off.
This is fixable: Everything has to be rendered at 320x240 (to retain correct AR), then before sending it to the screen, every line has to be doubled. Problem is that this has either be implemented in the display driver or in every app itself. No dingux software will work out of the box by just adjusting the resolution
