What's the problem? Describe what went wrong in few words.
The game crashes partway through Arcade Comp 2, when you reach the part with the bouncy balls. Any attempt to go to the up-right results in an exception and crash.

The exception reads:
IntCPU: Unknown Instruction 02d41400 at PC = 80650010 last_PC = 80001f18 LR = 801c9884.

Other exceptions are thrown after hitting yes, eventually leading to a hard crash of Dolphin. The crash also occurs when attempting to Jack Out of the area, which is probably easier to reproduce with.

This occurred with all three backends (Recompiler, JITIL, Interpreter) and both D3D11 and OpenGL.

What did you expect to happen instead?
No Crash

What steps will reproduce the problem?
[Don't assume we have ever played the game and know any level names. Be as
specific as possible.]

1. Play game until Arcade Comp - Area 2
2. Jack Out
3. Observe Crash

Dolphin 3.5 and 3.5-367 are old versions of Dolphin that have
known issues and bugs, so don't report issues about them and test the
latest Dolphin version first.
Which versions of Dolphin did you test on?
4.0-6587

Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?
The game worked fine in the past as reported by others as far back as the 3.0 days.

What are your PC specifications? (including, but not limited to: Operating

Win7 x64

Is there any other relevant information? (e.g. logs, screenshots,
configuration files)

I was playing with cheats enabled. I made a manual save, reloaded after exiting Dolphin, and the problem remained, so I don't think it's a cheat issue...

I do have a save right before the area in question, if anyone needs it.
