VisualBoyAdvance-M v2.0.0 Beta 3 Keyboard fixes is released. VisualBoyAdvance-M(VBA-M) is a [Super] Game Boy [Color / Advance] emulator for Windows, Linux & Mac. Here you can get information about the latest development build of the Windows version and download it while you're at it.

VisualBoyAdvance-M v2.0.0 Beta 3 Keyboard fixeschangelog:
Apparently in some configurations, holding a key on the keyboard makes
Wx stop processing Idle events, so the emulator does not run until the
key is released, freezing the game and ignoring the key.
Hopefully fix this by calling wxWakeUpIdle() from OnKeyDown() and
OnKeyUp().
Other Misc. Improvements:
refactor process_key_press() to only return true if the system is in a
pressed key state on key presses or a game key was released on
releases and always true on double releases.
call ev.StopPropagation() from OnKey* events for game keys, this may
not actually do anything, but just in case.
remove static OnKeyUp and OnKeyDown events from GameArea, these are
connected to the DrawingPanel dynamically now.
remove the dynamic_cast<>s from PaintEv/EraseBackground/OnSize event
forwarders, since there is already a panel member to use.
