0, a cross-platform plugin-based Nintendo 64 emulator. I only had to adjust one setting to make to portaits in MK64 working but the rest was just right. Mupen64Plus with custom plugins and Qt5 GUI (git version) Upstream URL: For some inspiration on how to design a proper GUI look at the following Nestopia, VBA-M, Kega-Fusion, SNES9x, ePSXe, Mupen64Plus-FZ, and yes as much as it pains me to admit even Project 64. While Mupen64 has not had a release since 2005, development on Mupen64Plus is active with releases every few months and support provided for all included plugins. Open up the solution file: mupen64plus-ui-console\projects\msvc8\mupen64plus-ui-console. Bugfix: GTK GUI: 'Toolbar Style' now works - Bugfix: Many other minor bug fixes, GTK warnings fixes, translation corrections, etc Mupen64Plus has a new Home Page over at Google Code, with lots of useful information, screenshots, a bug tracker, a discussion forum, etc.
