--- Comment #7 from Toni <eldrad at autistici.org> ---
I have investigated this error and found out these are the relevant error
lines:

0009:Call KERNEL32.CreateFileA(0033fb48 "C:\\users\\user\\My
Documents/Bayonetta/system_data",80000000,00000000,00000000,00000003,40000080,00000000)

data.",0033fc50) ret=00c71c9e

Turns out the program is launching an asynchronous operation on file read, and
badly checking error conditions, it seems to only accept the operation as
correct if it sees LastError set to STATUS_PENDING. The root error is because
wine doesn't respect the async command and just performs all file/reads in sync
manner.

Attached two alternative patches fixing the issue for bayonetta. The first one
just sets the error to STATUS_PENDING even if the operation is done
synchronous, this seems to allow the application to continue and indeed
read/write the files.
The second alternative actually runs the read/writes asynchronously through
wineserver.
