For those of you still regularly battling online in Pokémon Omega Ruby and Alpha Sapphire, or still firing up Pokemon X and Y for some matches, you'll have an update to complete before you get get on with the serious business of trading and fighting pocket monsters.
Both games have patches of around 250-270 blocks - so they're rather small - and apparently fix bugs in addition to tidying up some in-game text. We'd bet quite a few bucks that they also lock out some exploits or hacks, as is often the way with these sorts of updates; you won't be able to access online features until the updates have been completed.
Are you still playing ORAS and X & Y regularly? Let us know.
