EDIT: If you're playing on a Retroid Device or a device with a built in controller and can't get the controls to work in Vertical Mode for some games, there is a long fix. You have to set the "Console Options" in Swan.Emu to Vertical, rotate the screen in the Video settings to match the rotation side you want, then create a new controller profile (ex "Vertical") and remap the Joystick. Switch back as needed. I'll rate higher if someday it's automatic on game-changed orientation. Still a good EMU

Love the emu series of emulators. I am a little frustrated by the fact that my favorite filter (CRT) was replaced with two new ones and they seem to have some sort of problem where they are way too harsh and the wrong scale. For black and white games it would be nice to have colorization options like gbc.emu has.

Finally a great wonderswan emulator on the play store, I'm probably only going to play the first saga game but still well worth the price. Thanks.

What’s new

* Add a rewind button to the stock top-left virtual controls and only the show the rewind button when rewind states are set in the system options
* Add Options -> Frame Timing -> Low Latency Mode to keep the emulation thread in sync with the renderer thread to prevent extra latency, turned on by default but trying turning off in case of performance issues
* Default to the screen's reported refresh rate as the output rate if the device supports multiple rates
