--- Comment #4 from David turbolad995@hotmail.co.uk 2011-03-16 18:38:32 CDT --- I will keep testing this bug for each new update of Wine, which I receive via the Update Manager in Ubuntu.
So far it's the only bug I've found with Nestopia in Wine, otherwise Wine makes Nestopia run flawlessly as if it were running in Windows.
