#	Line 35 | Line 35
35		*  - Events processing is bound to the general emulation thread as SDL requires
36		*    to PumpEvents() within the same thread as the one that called SetVideoMode().
37		*    Besides, there can't seem to be a way to call SetVideoMode() from a child thread.
38	+	*  - Refresh performance is still slow. Use SDL_CreateRGBSurface()?
39	+	*  - Backport hw cursor acceleration to Basilisk II?
