When trying to start a new game the screen goes black and there is a high pitch noise, nothing happens.
What steps will reproduce the problem?

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.
Im using Dolphin 5.0-11268
Is the issue present in the latest stable version?
Yes Dolphin 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.)
[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.]
What are your PC specifications? (CPU, GPU, Operating System, more)
Core i5 8400
G.Skillz 16GB 2133 Mhz
Windows 10 1903
Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)
Anything you ask for

Nanook has done some testing, and it seems like the cause is files on the disc not being 32k aligned. The same problem happens on console.
So, in conclusion: Use a good dump and it'll work. (Maybe Nanook will also release an update to NKit to handle this problem, we'll see.)

That turned out to not be the underlying cause. When the game reads setup/aa1_01.dat, it doesn't just read the data of the file, but also a few extra bytes beyond the file, so that the length of the disc read (or the offset of the end of the disc read?) is divisible by 0x20. If these extra bytes are 0, the game works. I'm not sure if it breaks for all non-zero values, but there are certainly some where it breaks. Cases where the bytes are not 0 and the game fails include having the files packed together too tightly (making the read of the first file include data from the beginning of the next file), and having the NKit "gap data" be present after the file.
