Emulator

Does the Verify tab of the game properties show any problems?

Yes, two with severity "low"

-The format that the disk image is saved in does not store the size of the disk image.

-Errors were found in 108342 unused blocks in the DATA partition.

Problems with low severity were found. They will most likely not prevent the game from running.

Btw I played this game a lot of times, so I think there's no problem with the image disk dump, and some games, for example archery, works fine in the 1 player mode. But in two player mode only blackscreen.

Can anyone else confirm this?

If those are the only problems that it reports, then I don't think it's the disc image.

Do you mean that you have played the game in previous versions of Dolphin without any problems? If so, please bisect the issue (as described in the issue report template).

Yes, and worked fine. But the last time I played this game was a year ago more or less. I'll try to bisect in this week if I got enough time.

After MANY tests, I think I found the problem, more or less...

The problem is related with the mii info stored at "/user/wii/shared2/menu/facelib/RFL_DB.dat it seems that dolphin cant read this info because the mac changes sometimes.

Closing...

Ok... can't close this issue in the mobile version... I'll close tomorrow from my desktop PC if anyone else don't close it first.

Can't close in desktop too. So please, anyone with the needed rights can be close this. Thanks.

Forget about it, the issue persist. I Tried to re-assign my miis (And worked in all related games) but blackscreen again.

Tried to delete RFL_DB.dat and create a new one (By opening mii's channel and create new miis) the same result. This game just blackscreens when he try to read the RFL_DB.dat when two players are selected.

One more time, steps to reproduce the issue:

Have a /user/wii/shared2/menu/facelib/RFL_DB.dat file (This is created when you create miis via Mii channel)

Try to start a 2 player game in archery game. - Blackscreen-

Tested with the latest builds and builds from more than 6 months ago. Sorry but I can't see a working build from this point.

Sorry, is not a dualcore issue, and not a nand issue. I can assure you that my nand files are ok and other games that depends on this files are working fine.

The only problem here is the RFL_DB.dat file. I don't know if you have miis created through the mii channel. In my case, if I delete or move this file, the game works very well. The problem is when this file is present "only for this game" it doesn't matter if you have a fresh dolphin install, if you import or create frow scratch a mii on the wii channel. If the file is created through dolphin or imported from a real wii console. If you have this RFL_DB.dat file under "user>wii>shared2>menu>facelib" the archery game for 2 players gots a blackscreen.

Please, test it, and reopen this issue if you got the same problem.

Ok, after more than 1 **cking hour testing. I got where the issue is:

The game blackscreen in the games "specially the archery game in two players" if you have a (RFL_DB.dat file + EFB Copies to Texture Only disabled)

This can be solved by disabling one of them. Removing the RFL_DB.dat file, or enabling EFB Copies to texture only, "But in this case, the miis on the archery game becomes invisible)

Any tip to solve this by enabling the EFB copies to texture and get the miis visible?

Thanks a lot.

Note: "Only to clarify" the miis becomes invisible with the EFB copies enabled when the zoom comes in to shoot the arrow. The miis are visible before this. The hud also dissapears with this, and you cannot see the wind direction.

But in your case, can you see the miis invisibility problem when the zoom comes in "when you shoot the arrow in the archery game"?
