* When using Windows on some handheld devices with AMD GPUs, ES-DE will only display a black screen on startup. This can be seen on for instance the Steam Deck, AYA NEO and ONEXPLAYER 8.4. The issue seems to be caused by buggy GPU drivers, and can be worked around by specifying a window size for ES-DE that is a single pixel larger than the actual screen resolution. So for example for a 1280x800 screen, the resolution can be set to 1281x800 and it should then work correctly. This is applied using the --resolution command line option, for instance `EmulationStation.exe --resolution 1281 800` * When using Windows on some handheld devices with AMD GPUs, ES-DE will only display a black screen on startup.

* On Windows when using high DPI displays, if not running ES-DE on the primary monitor and the display where it runs does not have the same scaling percentage as the primary monitor, then the ES-DE resolution will not be properly set. The application will still work and if running in fullscreen mode it may not even be noticeable. This issue is probably caused by a bug in SDL where the primary display scaling is always used for calculating the display bounds. If using the same scaling percentage across all monitors, or if not using high DPI monitors at all, then this issue is not relevant. * On Windows when using high DPI displays, if not running ES-DE on the primary monitor and the display where it runs does not have the same scaling percentage as the primary monitor, then the ES-DE resolution will not be properly set.

Another specific area where help is needed is to research and potentially develop a usable web version of ES-DE. A proof of concept compilation to WebAssembly (using Emscripten) has been done and the application actually runs somehow correctly in a browser. But it needs to be investigated whether games/emulators can actually be launched when running in this environment and there are many improvements to be completed before the WebAssembly build is usable.

### Release roadmap ### Release roadmap
The roadmap is under constant review so expect it to change from time to time. Still it should give some feeling for which direction to move and what to work on first. These are only the larger topics, there are of course many smaller changes and improvements in addition to these. The plans for previous releases are shown in italics.

In order for ES-DE to run, graphics drivers with OpenGL support have to be installed. If not, the application simply won't start. For really old graphics cards the available drivers may not provide an OpenGL version that is modern enough for ES-DE to work, and in this case a last resort solution would be to install the _Mesa3D for Windows_ library which provides software-based OpenGL rendering. The 64-bit version of this library can be downloaded from [https://fdossena.com/?p=mesa/index.frag](https://fdossena.com/?p=mesa/index.frag) and you simply extract the opengl32.dll file into the ES-DE installation directory.
