I am aware that there have been updates since the glitch was originally possible but could the glitch still be performed if the updates where deleted?
This was patched in version 1.1. If you have an unpatched version of the game, then the glitch is still possible. Here's the map from Nintendo of where not to save in.
If you update to version 1.1 or newer, the glitch will be fixed as well as your save if it was affected by it.
