Dolphin, the GameCube and Wii emulator - Forums

Yesterday I downloaded Dolphin (i know literally nothing about emulators so bear with me) so I could play some old NHL games, and I found the only way NHL 2005 works is with MMU Speed Hack enabled. However, when the speed hack is enabled, the game become too fast and difficult to play. The commentary and music is still audible but just sped up and slightly annoying.

Is there any way to slow the game down to its normal pace?

Your profile says you are using 4.0, update to at least 5.0 and try again (we don't support anything less than that).

The MMU speedhack doesn't actually speedup anything to do with emulation, so whatever you're talking about is 100% unrelated.
