[Fixed] Fix wrong logic of snapshot inconsistent with movie

Post by gocha »

One of fatal glitches since 1.51.

Code: Select all

diff --git a/movie.cpp b/movie.cpp
index de5dc48..9286b8f 100644

+++ b/movie.cpp

 	else
 	{
-		if (current_frame > Movie.MaxFrame || current_sample > Movie.MaxSample || memcmp(Movie.InputBuffer, ptr, space_needed))
+		uint32	space_processed = (Movie.BytesPerSample * (current_sample + 1));
+		if (current_frame > Movie.MaxFrame || current_sample > Movie.MaxSample || memcmp(Movie.InputBuffer, ptr, space_processed))
 			return (SNAPSHOT_INCONSISTENT);
 
 		change_state(MOVIE_STATE_PLAY);

Committed.

Also, if you post any more patches, could you just upload them somewhere like pastebin instead of putting it directly in the post? The Snes9x forums badly mangle the whitespace.

Thank you very much, I'll do so next time.
