2 things I would like to have:

A ) Option to disable the savestates: This rom is played mostly on everdrives /powerpaks /emulators, and all of them have built-in savestates options. Unless you are playing on a repro cart, there is no real use for that options (except maybe for restart game) and the built in ones takes priority over the catridge combinations (at least on everdrive).

B ) Is possible to add an option to disable music? Useful if you want to stream some practice and put some music, so you can have special effects sounds and listen to your music without having to mute all game sounds in the stream.

If the video is recorded a 30fps, you need to use divide by 30 and not 29.97. The only time that you need to do a different framerate is when a NES or SNES game is running on an emulator or VC, because there the game is running slowly and you need to compensate for that difference (60.09fps vs 60fps)

And it seems that YUA or VirtualDub do the most accurate "frames to time" calculation, doing both the same results that arcus got with a 3rd software.
