byuu says: Most notable in this release is that sound support has been added to my own Super Game Boy emulation. The GUI toolkit, phoenix, has also received a complete rewrite; with the most visible change there being that windows are now resizable. Changelog (since v075): * added sound emulation to Game Boy core * fixed Super Game Boy save state * support added HexEdit widget to Windows and Qt targets; debugger can now be compiled on all platforms * entering fullscreen now auto-hides mouse; and mouse capture is toggled otherwise by F12 key * fullscreen command and geometry caching works much better on GTK+ and Qt targets * phoenix rewritten from scratch; now supports resizable layout containers * phoenix/Windows no longer relies on buggy SetParent API to reparent widgets
