﻿Fixing or disabling the "Download Codes (WiiRD Database)" button problem

The "Download Codes (WiiRD Database)" button is enabled (and its click return silently without an effect) when "Tools → Cheats Manager" is opened when there's a running emulation for which there's no "[Gecko]" ini section, confusing the user about the reason for not downloading codes or showing an error when there's no running emulation

Solution

when there's a running emulation: fix the button

when there's no running emulation: disable the button (to indicate to the user that this button must be clicked elsewhere, in the ISO settings dialog, the user will realise or remember)
