Broken DVD games don't throw an error when installing

[GoogleCodeExporter]

Hi,

When I try to install a game that doesn't work (the original) on the Wii, 
Wiiflow completes up to 100%, but the game is not playable. In fact, on my 
sister's Wii, doing this has made all the installed games to stop working.

Both Wiis are 4.2E, using CIOS222v5 and WiiFlow r114, i think, and WBFS 
partition.

How should a loader know if a game is broken?
It check if the game is for Wii and then it just copy the data. I think a test 
run is impossile because how should the loader know if it starts properly? It 
shuts down after booting.

And why are you installing broken games?

"doing this has made all the installed games to stop working" this just isnt 
possible.

Probably "broken" is just not the word. The word is "scratched" discs. We are 
trying to install them because it is just not possible to play with them 
through the disc channel, so we thought that may be the loader could make more 
retries upon reading.

And the WiiFlow could know if a game has been correctly installed by checking, 
e.g., a checksum of the whole disc (and comparing against a db that probably 
doesn't exist yet); anyway, progress bar jumps from e.g. 40% to 100% suddenly, 
and this is a condition that the software can detect, for sure.

And miigout@hotmail.com, I am not complaining against WiiFlow, I only state 
what has happened. Probably, a bad install has damaged the WBFS partition or 
something like that. We will try to reinstall all the games, but it will take 
time.

Thanks again

I agree with the other two comments - this isn't really possible.  If the Wii's 
optical drive can't read a disc then it can't read a disc.  Forcing it to try 
20 times wont change that.  It would be a lot easier to just download or 
generate a copy of the game from a computer and import it to the wii that way.  
Does the game disc read (and copy 100%) correctly in a computer?

Well, as I said, the loader can detect data not correctly read and then cancel 
the overall copy proccess (by making a block data checksum, e.g., or when 
timeout conditions are met). In an ideal world, checksum against a GameSumDB 
would be nice, but I understand that this is not easy to implement. But the 
first idea would be nice to have, to avoid incorrectly installed games.

I'm still waiting to my sister to bring her Wii and HDD to check what went 
wrong. If I get further information I will post (about the fact that all the 
games that were working are not working after "scratched" games install).

Thanks.
