Tales of Fridays?

So, for whatever reason, nobody's been around to play Tales for the past couple of Fridays.  The few of us that have been there have been playing the Scott Pilgrim XBLA game.  I've ground two characters up to max level and stats now, which I have to do by myself because when I play with other people I seem to get the short end of the stick.  100 speed is way too fast, especially when hyper mode is on.  All I need to do is get them to level 6 and buy the hidden move...

I haven't been doing my grinding in the most efficient way possible either.  Basically, I grind money and use the hidden store in Level 1.  Yeah, I haven't been paying off Scott's late fees.  Two bionic arms, three never-ending fantasies (and random WP+DEF items from other stores to get the remaining 10 of each), and two speedy the porcupines.  It's expensive, but whatever.

I should actually play through the game with the characters I've maxed out now.  I've maxed Ramona and Stills, and started money grinding for Kim but don't have enough to buy anything yet.  I really like Ramona's striker.  Full group hyper mode go!

The Invulnerable achievement is really easy to get.  All you have to do is have a friend go in the game with you (and both of you can get it!).  Go into level 1, one player blocks, rolls around, and avoids the big enemies; the other player kills everything.  Use the shortcut, avoid busses/cars, etc.  The achievement unlocks before the fight with the boss, so you can fight him without having to worry (it's not like I haven't OHKO'd him with Ramona's dashing hammer attack...).  Then go through again with the roles swapped and both of you will have it.

I'm going to have to remember the codes on GameFAQs' codes page.  How do people find these things anyway?
