Emulator

That is correct. 5450 does break while 5445 works.

Just following up on this. Over 1000 builds later and 4.0-6842 still has this same problem.

This is an issue with CPU emulation, I can't really help there.

an unclosable error pops up

Hang on, what does the unclosable error say? Just because it's unclosable doesn't mean it's meaningless.

The errors are like this:
Invalid Read from to 0xffffffff, PC = 0x801d2020
Invalid Read from to 0xffffffff, PC = 0x801d2038

I don't have any documentation on that particular routine, but it looks like some out of range issue?

The actual invalid read will be coming from somewhere inside dolphin's code, based on bad information the game has given it.

Any chance you know how to attach a debugger and give us a stack trace while that error is showing?

If it's anything that isn't the built-in Dolphin debugger, then I wouldn't know. I've been able to build Dolphin from source before though. Would that be of help? Otherwise, I would be able to help you get the error to show up.

How are you loading the DLC? Can you provide the steps to do that? Are you loading anything off of SD Card?

Through the NAND. I've never gotten the SD card way to work.

Download this, which should have all the files necessary.

SYSCONF might need to be replaced again after the game has been run once to prevent the game identifying as a PAL system and looking for DLC in the PAL directories and files.

Does Dolphin outright crash after the popups? If so, let's try another angle. Get the latest build of Dolphin (note which version you're using)

When Dolphin crashes, do not close it, open up task manager and find Dolphin in the process list. Right click it and "create dump file" or whatever it's called. Then,note the location of that file, compress that file and upload it somewhere we can get it. That should give us more information to debug it.

Actually, creating a dump file at the first int-cpu popup will work as well, apparently. If you do this, we should be able to debug it further.

It's kind of really large. Dolphin doesn't outright crash, but I have to force close it with the Task Manager because it loops infinitely.
So here is a dump file taken after the first error message on the main menu.
https://dl.dropboxusercontent.com/u/42704237/Dolphin-4.0-6896.rar
It's from the latest as of this post which is 4.0-6896.

So, let's try something. What happens if you right click the game, hit game properties, and enable MMU emulation?

If that doesn't work; what happens if you disable panic handlers?

When MMU Emulation is on, the game just soft locks at the main menu instead of showing the messages.

If Panic Handlers are disabled, then everything actually proceeds as normal! DLC loads just fine and plays too.

Go to view, show log configuration, turn on all log types, then turn off "Video Backend" to prevent some spam. Now, open up the Show log window. Now, run the MMU emulation on. Hopefully when the game soft locks, it will send some information to the logs that will helps us out.

Thanks again for your continued patience in narrowing this down.

Here's what the log starts to look like around the lockup. The last line is repeated very frequently; within milliseconds.

That looks incomplete. Can you post the whole log?

Okay, here's the whole log from boot to lockup. A lot of the early errors are to be expected.

This issue might also be affecting DLC for The Beatles Rock Band. While the game detects it, it fails to actually play any DLC, getting stuck on the load screen.

Here's a pastebin of the log up until that point.

There is no error message associated with it, but it might be failing for the same reason as described.

The DLC files you posted don't seem to be detected by the game. At least for me.

I'm actually still getting this issue, specifically with Beatles Rock Band DLC. It shows up in the menu, but when I select it the song infinitely loads, never actually finishing. I can play through on disc stuff just fine, it's just the DLC I've got issues with

I do have a programming background, and if you could provide a bit of guidance leoetlino I might be able to get the issue fixed with a PR.

What would you need from me? I have the DLC files and set them up in a way that should work, but they got stuck in loading like you described last time I tried.
