What's the problem? Describe what went wrong.
When playing the game, I am getting stuttering. When this happens, the following info appears in the logs:
29:22:411 core\hw\mmio.cpp:188 E[MI]: Trying to read 8 bits from an invalid MMIO (addr=0ccd1fe4)
29:22:411 core\hw\mmio.cpp:188 E[MI]: Trying to read 8 bits from an invalid MMIO (addr=0ccd1fe5)
29:22:411 core\hw\mmio.cpp:188 E[MI]: Trying to read 8 bits from an invalid MMIO (addr=0ccd1fec)
29:22:411 core\hw\mmio.cpp:188 E[MI]: Trying to read 8 bits from an invalid MMIO (addr=0ccd1fed)
Sometimes these errors happen for prolonged periods, resulting in a choppy experience.
What steps will reproduce the problem?
[Reproduction steps here]
Using the latest development version (9569), launch Project M, and start a vs. fight (E.g. Fox vs. Random), then pick Hyrule Castle. As you play, you should start to encounter stuttering and the aforementioned errors.
[Version number here]
Is the issue present in the latest stable version?
The errors occur in the stable version, but they do not cause stuttering.
[Yes/No and version number here]
If the issue isn't present in the latest stable version, which is the first broken version? (You can find the first broken version by bisecting. Windows users can use the tool https://forums.dolphin-emu.org/Thread-green-notice-development-thread-unofficial-dolphin-bisection-tool-for-finding-broken-builds and anyone who is building Dolphin on their own can use git bisect.)
[First broken version number here (if applicable)]
If your issue is a graphical issue, please attach screenshots and record a three frame fifolog of the issue if possible. Screenshots showing what it is supposed to look like from either console or older builds of Dolphin will help too. For more information on how to use the fifoplayer, please check here: https://wiki.dolphin-emu.org/index.php?title=FifoPlayer
[Attach any fifologs if possible, write a description of fifologs and screenshots here to assist people unfamiliar with the game.]

Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)
