Emulator Issues #408
closed
DVD IOCTLs are Buggy on Wii Games
0%
Description
What steps will reproduce the problem?
- Load up Medal of Honor Heroes 2
- Confirm PANIC!
- Watch game do nothing/
What is the expected output? What do you see instead?
I would expect the game to boot up to the menu. Instead it comes up with an
error and does not proceed further.
What version of the product are you using? On what operating system?
SVN 1556 Windows XP 32-bit.
Please provide any additional information below.
I have determined it to be a DVDLowUnencryptedRead error in
WII_IPC_Device_DI.cpp. It receives 0x8c as the command, and it is not
accounted for. I have no idea how to solve this issue but I have found
something online which may help to understand what the Wii is looking for.
The highlighting will show you the DVDLowUnencryptedRead code.
Hope this helps!

There doesn't seem to be an edit. But it is supposed to have a better title, and it
is getting 0x8d and not 0x8c.
And know what? I think http://wiibrew.org/wiki//dev/di might have a better idea on
what to do with DVDLowUnencryptedRead .

IMO fixing something like this should get a lot of games working.
Updated by foldor over 15 years ago
After viewing the wiibrew page and the DVD API created by Jeff Epler. I think I have
figured out that the exact same code used for DVDLowRead, can be reused for
DVDLowUnencryptedRead. I tried this out, and it does manage to get further when
running the game, but now it gets stuck at DVDLowClosePartition or 0x8c. I am
currently trying to figure out how all of this works, to see if I can create a fix
and will keep this up to date if I make progress. But if any of the developers with a
more intimate knowledge of the Dolphin code want to take a crack at it please do.

House of the Dead Overkill still has the same issue in r4017
I guess its an instruction not yet implemented in Dolphin, maybe something to do with
game protection perhaps???

House of the Dead Overkill hangs because it reads PE Token forever. That is a different
issue.

@ godisgovernment
r u sure? here I have posted a log :
http://code.google.com/p/dolphin-emu/issues/detail?id=956&can=1&q=dvdlowseek#c9
from the booting of HoD Overkill, it doesn't seem like an endless loop. And browsing
at the source code, I found that those instructions are not actually implemented...
correct me if I'm wrong, I just want to help as much as I can.

tried house of the dead overkill with r4384 and now i get this log:

More messages that perhaps can show the reason behind this game not booting...

It looks like Okami works with unlimited JIT cache. Unfourtinately, you can't exactly
see anything but the overhead display. The in-game menu is also buggy, displaying
graphics in the wrong positions. Tested with r4388 release build with "/d" commandline.

@ arslanoglou
i'm sure...
these logs:
30:00:171 W[WII_IPC_DVD]: DVDLowUnencryptedRead: trying to read out of bounds @
460a0000
30:00:171 W[WII_IPC_DVD]: DVDLowRequestError status = 0x00052100
30:00:171 W[WII_IPC_DVD]: DVDLowRequestError status = 0x00052000
are normal. That's one of the ways the game checks to see if it's running on a
modchip'd/modified system.
afaik, /dev/di emulation is correct (as far as games use it, anyways), feel free to
prove me wrong.
