I honestly think the only way is to manually decline the update. I'm nowhere near my Wii right now but if memory serves me correctly there is no way to stop Tantric's Nintendo emulators from auto updating. I don't think there is an auto-update on/off in any of the options. But you also have to weigh which is more important to you...Having an up to date program with all the latest features or using an ancient version just to launch from covers rather than titles. I chose to keep my emulator up to date when I tried the cover versions of FCE Ultra GX and Snes9x GX. I mean the emulator versions that the cover version are based on are over a year old and several improvements and fixes have been made since then.
