Ishiiruka could use a hack similar to VBeam to solve that and maintain the audio at normal speed at 60 FPS. It indeed required the VBeam hack which was quickly removed. The old 60 FPS code was a patch and did not work very well on Dolphin. In other words, there aren't that many more cutscenes after you have collected your first star at the airport. The only issue with this 60 FPS code is that cutscenes run slowly, but then again, how many cutscenes does this game have. Just check the wiki page for Super Mario Sunshine. There is also a Gecko code for a 16:9 Aspect Ratio Fix. Just add and enable the 60 FPS (Region-Free) code as a Gecko code. There is no need for a custom build such as Ishiiruka. The 60 FPS code works fine on the latest official development version.
