Override AdminProductsController in 1.7.8.2

[cvirus]

Is it possible to do an override of (AdminProductsController extends AdminProductsControllerCore) to display some buttons with initToolbar() and $this->toolbar_btn under module/override/admin/AdminProductsController.php.

 

I'm trying to update an old 1.5->1.6 module that worked like that and now it isn´t working.

 

Thanks.
