I wish there was some way to ease the burden of this playthrough.  Games with dynamic events and challenges are incredibly difficult to offer strategies for, as the solution changes with every action that is made.  Even if you know the right shots to make (especially on the gold brick puzzle stages), the enemies will do their best to ruin your trajectory.  It's hard to say this, but all you can rely on with Arkanoid is your reflexes and eye-hand coordination.  There will be times where you have less than a second to react, mostly due to an enemy in proximity to the Vaus and ball, and no amount of strategizing beforehand will be of use.

Good luck on this one; you're definitely going to need it.

Finally!  I can't wait to bust some Aragami with you .

That said, it's so much easier searching for, well, anything by using their website.  At least there we can make use of Google's site search function and find stuff that Sony's search engine ignores.

Whew... I found it!  I went searching through the PlayStation community site and found a discussion about Ad-hoc Party.  At the moment, because Sony has once again rearranged the storefront, the easiest way to download the program is through their website.  Here is the direct link to the program.  If you're using NoScript, you'll have to visit the site first and allow some scripts through and then click on the link a second time.  Once there you can log in to your PSN account, "purchase" the program, and it will show up on your purchase list on your PS3.

As for why Sony hasn't taken better care of their program, well, that's because they considered the PSP a failure in the West.  Adding insult to injury, we didn't even get the enhanced version that had added features and other connection tricks (especially for the PSP-to-PS3 ports that retained their multi-player modes).
