I think it would be really nice if emulator used to playback (mupen,shex9x,vba,fceu,gens) could display subtitles from srt file during movie playback. Srt is widely used and most simple subtitle format, same file can be used with avi. File looks like this (just copy-pasted first SRT i found):
1
00:00:17,893 --> 00:00:21,653
Pai...Take this...
2
00:00:21,653 --> 00:00:25,553
Someday...
I'll make you human...
3
00:00:25,553 --> 00:00:27,503
I...promise...
...
The only features needed are:
recording:
- Create subtitle file
- Start subtitle here (asks for text)
- Hide shown subtitles
- Save subtitle file.
playback/editing:
- Open subtitle file
- Show subtitles (toggle).
Not much work, I think...
Why would it be needed?
1) Comments for movie can be shown while viewing movie. Skipped parts can be explained for those who never played, used tricks for those who has played, but did not know about it. "You know, I just skipped 5 boss rematches! :D"
2) Somethhing funny can help watching through boring parts
Of course subtitles can never be taken in consideration when deciding if movie is going to be published or not.
