(From update of attachment 14004)
Hello,

revisiting.
Invalidating one patch as it doesn't apply cleanly anymore and to ping any
takers.

If you manage to get the three issues fixed in near future, I might give you
more hints to work around other pb problems.
There will be a day when the interest to help with such bugs is gone ...

As already told, the other two issues are simple fixes.
The third problem can be split in several parts.

For a start supply a minimal impl of ntoskrnl's MmGetSystemRoutineAddress to
keep the kmode driver surviving the initial ioctls.

002e:trace:ntoskrnl:MmGetSystemRoutineAddress L"ZwQuerySystemInformation"
resolved to 0x7bc4d850
002e:trace:ntoskrnl:MmGetSystemRoutineAddress L"MmMapIoSpace" resolved to

002e:trace:ntoskrnl:MmGetSystemRoutineAddress L"MmUnmapIoSpace" resolved to

002e:trace:ntoskrnl:MmGetSystemRoutineAddress L"MmGetPhysicalAddress" resolved
to 0x60596690
002e:trace:ntoskrnl:MmGetSystemRoutineAddress L"ObDereferenceObject" resolved
to 0x6059708c
002e:trace:ntoskrnl:MmGetSystemRoutineAddress L"MmIsAddressValid" resolved to
0x6059aeb0
002e:trace:ntoskrnl:MmGetSystemRoutineAddress L"PsLookupProcessByProcessId"
resolved to 0x60597d10
002e:trace:ntoskrnl:MmGetSystemRoutineAddress L"KeStackAttachProcess" resolved
to 0x60595fd0
002e:trace:ntoskrnl:MmGetSystemRoutineAddress L"KeUnstackDetachProcess"
resolved to 0x6059603c
--- snip ---

The driver calls ZwQuerySystemInformation to retrieve page size etc. (see
comment to make ZwQuerySystemInformation() return more useful values for
SystemBasicInformation class).
Hence MmGetSystemRoutineAddress can't simply return NULL (driver would simply
refuse to work).

The other APIs resolved by MmGetSystemRoutineAddress will be needed later
depending on PB client/server versions and capabilities (differs between
games).
It's ok to leave them as they are for now.

Regards
