RS 97 Plus series

The RS-97 Plus is an evolution of the original RS-97, adding a larger battery and a slider controller nub. The first version used a 30Hz screen and was univerally derided. Version 2 finally added a 60 Hz screen back in, while the Anniversary Edition upgraded the screen to IPS, and added dragon highlights (but is still considered a v2). Important note about the IPS/Dragon version is that mass storage does not work on RetroFW. Also, while the device was revised significantly, accessing the internal SD card still requires unscrewing and removing the back of the device.
