Version info
Users on Windows who want to record PC Engine / TurboGrafx-16 movies should use http://code.google.com/p/pcejin/
pcejin is sync compatible with Mednafen but provides a much smoother experience in Windows.
The latest SVN of Mednafen is able to play pcejin movies, but it cannot play older mcm or play/record anything except PCE. Due to a slight change in the movie format earlier mc2 movies are now incompatible with both pcejin and the latest Mednafen SVN. mcm-mc2 also creates movies that are incorrect for the latest versions. To fix this, buttons 1 and 2 must be swapped in the movie file, since the earlier versions had these two buttons incorrectly reversed.
If you want to make a movie for other platforms get mednafen-rr-1.1-win32.zip for Windows, or on Linux, check out and compile r144.
