Get setjmp/longjmp to work in Emscripten without it slowing things down. This is necessary for some games like SimTower. (update: 11/27/2017 Currently waiting for WASM to support this)
Save/Load state, not sure how this will work with OpenGL, needs research
Android port
OPL2 and PC speaker support
Create a custom Wine audio driver for BoxedWine, instead of using wineoss.drv.so and emulating /dev/dsp
Port x64 dynamic recompiler to Mac/Linux
Implement dynamic recompiler for WASM/Emscripten
Add support for winetricks
Add support for clipboard (used to work in an earlier version of BoxedWine using Wine 1.6, winex11.drv change how the clipboard worked starting in Wine 1.7)
Done
19R1 Improve OpenGL support so that it can be used with DirectDraw games like Age of Empire
19R1 Relative mouse support so that FPS games can use the mouse
