I finally got VirtualDub working with the Avermedia card (except some audio desync issues but can be fixed), so i wanted to provide a sample recording which beats the game using warps: http://www.filedropper.com/yuahq

I did some testing between Wii/Wii u VC and noticed Wii U version runs slightly faster. I started timing both versions when the timer appears in top right corner and stopped on time up (the frame marios death animation starts).

For Wii U, i used AverMedia's Recentral and captured/recorded at 60fps. The result was: 9634 frames / 60 = 2:40.5666666666667 (160.5666666666667 seconds)

For Wii, i used VirtualDub and captured/recorded at 59.824fps. The result was: 9625 frames / 59.824 = 2:40.8886065792993 (160.8886065792993 seconds)

With BizHawk emulator the result is: 9625 frames / 60.098814 = 2:40.1529108378079 (160.1529108378079 seconds)

Calculating (inconsistent) fps: 59.824 ¤ 160.8886065792993 / 160.5666666666667 = 59.94394851567365 or 60.098814 ¤ 160.1529108378079 / 160.5666666666667 = 59.94394851567365

After those tests i wanted to time Wii U again but captured/recorded at 59.94 fps. For some reason VirtualDub didn't allow me to change the fps with AverMedia GC550, however i was able to do that with OBS Multiplatform 0.12.3. The result was: 9625 frames / 59.94 = 2:40.5772439105772 (160.5772439105772 seconds) When this is adjusted for NES, the time matches with BizHawk: 160.5772439105772 ¤ 59.94 / 60.098814 = 160.1529108378078

So based on this information Wii U VC seems to run at ~59.94 fps. I hope someone can confirm this. Should Wii U times be multiplied by 59.94/60.098814? Thanks :)
