Emulator

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.

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.

great job foldor , keep up the progress. this problem may fix alot of games

best place to talk to the dev team is on irc efnet server in #dolphin-emu on are new
website click Chat Room.

Issue 446 has been merged into this issue.

Issue 956 has been merged into this issue.

someone please test:
Medal of Honor Heroes 2
Okami
Other wii games?

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???

@ 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.
