This is a maintenance release, but it offers a lot of bug-fixes and speed-ups, so it should be well worth the update. The debugger is not finished yet, so use it at your own risk. It is disabled in the binary release because breakpoint testing impacts performance. Once it is ready, I will release a separate binary with the debugger enabled.

Changelog:
Optimized S-PPU emulation, provides a ~10-15% speedup in normal games
Cleaned up cheat editor user interface
Added save state and export data path selections

Added read/write/execute breakpoint support
Added memory editor (currently it can only view memory)
Various code cleanup work, as usual (note: the debugger code is messy, as it is in-progress)
