What's the problem? Describe what went wrong.
The game displays a backpatch warning and then crashes. It happens in both game modes and on the first segment of the main menu alternative screens.
What steps will reproduce the problem?
Boot the game.
Don't press anything (normally the game will display one of several segments displaying gameplay footage or cinematics.)
In the first segment the character will start running forward and the game will display the following Backpatch warning:
Backpatch: no register use entry for address 0x1dd1ccd9afe
The numbers differ every time. But only one warning appears before Dolphin crashes. Clicking OK or Ignore for this session will crash the game.
This is when the little in-game segment would normally attack an ornament. Attacking in either of the two playable game modes, "Conquest Mode" or "Gladiator Mode", will also display the warning before the game crashes.
Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.
Yes, 5.0-15613
Is the issue present in the latest stable version?
No, 5.0
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.)
5.0-14829
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.]
What are your PC specifications? (CPU, GPU, Operating System, more)
i7-8750H
GTX 1060
Windows 10
8GB DDR4
Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)
Let me know, I'll see what else I can do.

Turning on MMU does fix it, but we should figure out why.

The underlying issue is that paired loads from memory which has no physical mapping aren't correctly handled unless memchecks are enabled or fastmem is disabled. This issue has existed for a long time, and 5.0-14829 just happened to uncover it by disabling physical mapping for certain memory that had physical mappings before.
