Description

Game Name: F-Zero GX

Game ID: GFZE01

What's the problem? Describe what went wrong in few words.
You get spammed with panic message boxes with the following message: Invalid Read at 0x23801ce0, PC = 0x801bb514. This increases slightly each time you click OK.

If you disable Panic Handlers then there is a massive amount of glitches occurring causing the game to be unplayable. Most notable one being that the player and all AI spawn at what appears to be 0,0,0 on the track and you instantly lose.

What did you expect to happen instead?
For the game to be playable without any major glitches.

What steps will reproduce the problem?
Start the game up, it is visible as soon as the game starts, otherwise pick any track and attempt to play it.

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?
4.0-3746 (Panic if game does an invalid memory access) causes the problem.

Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?
Yes, 4.0-3743 and all others I have used before it do not show this problem.

What are your PC specifications? (including, but not limited to: Operating
System, CPU and GPU)
Windows 8.1
Intel i7 5960X (With HT enabled)
Nvidia GTX 780

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

It is an issue with fprf, the renaming of the option doesn't seem to work.Should be fixed by https://github.com/dolphin-emu/dolphin/pull/1351/files

Actually https://github.com/dolphin-emu/dolphin/pull/991 seems to be the cause and only mmu fixes it. That plus the fact sync gpu is broken and it needs single core for stability, plus the fact that the game now needs a projection hack for videos to display, it is FUBR in master currently.

A bit unrelated but i couldn't boot it with opengl and found out that i had a 24 gbyte! shader cache for this game, and gbytes of shader cache again only with opengl and only with games that i used single core or sync gpu for stability.

Maybe that's related to the sync gpu bug?

See here, something is wrong with shader cache and opengl when using single core http://prntscr.com/4yalui.

fixed by 4.0-3764 -> https://dolphin-emu.org/download/dev/9adf608f38a1e333f5ce30446ec7860ea4c164ef/

But, this may just be a hack of some sort that shouldn't work at all but does; as how dolphin was behaving before the merge that broke it.
