Emulator

In Mario Party 8 when I were in the minegame menu. The preview video of the minegame it wasn't in his site corectly it was move for the right side.

You can see my configuration and the screenshot of the problem in the images attached in this request.

The versión of dolphin was 5.0-15667.

I can confirm this issue happens on Dolphin but not on Console.

This issue only occurs when the game is in widescreen mode. If you choose 4:3 in Config -> Wii -> Aspect Ratio, then it should render correctly.

The actual issue seems to be related to the game drawing outside of the viewport (but within the scissor region) for its prerendered videos; Dolphin lacks the guardband and thus clips it overly aggressively resulting in blackness on the left side. Here are some images of how it renders internally: visualizing the viewport, behavior on hardware, behavior in dolphin, and location of EFB copies. Unfortunately this is something that will be annoying to emulate properly.

(I've also removed duplicate copies of the attachments.) (Also, the black borders versus borders with a decorative pattern in 16:9 mode is a game revision difference; PAL rev 0 and USA rev 1 have the decorative border and PAL rev 1 and USA rev 2 do not (to my understanding).)
