Citra gsp-command-synch Git (2014/08/06) is compiled. Citra gsp-command-synch is a branch of Citra. Citra is an experimental open-source Nintendo 3DS emulator/debugger written in C++. At this time, it only emulates a very small subset of 3DS hardware, and therefore is only useful for booting/debugging very simple homebrew demos. Citra is licensed under the GPLv2. Refer to the license.txt file included.

Citra gsp-command-synch Git Changelog:
* GPU: Updated g_last_ticks variable to be more descriptive (represents CPU tick count of last vertical line).
* GPU: Updated horizontal sync line counter to use framebuffer height.
* Thread: Added more descriptive comment to WaitCurrentThread.
