Just had a chance to read all the posts...thanks for all the help.

I never added the contents of registry but for reference this is what it would it added:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Remedy Entertainment\Max Payne 2\Game Level]
"normal"=dword:00000001
"LevelSelector"=dword:00000001
"nightmare"=dword:00000001
"timedmode"=dword:00000001
"hell"=dword:00000001

All I wanted was an 'any level' cheat as one level seems to be corrupted and I wanted to skip past...that was posted so many thanks.
