The best game on mine right now--and the ONLY thing my wife likes about the PDN (so far?)--is Andoku 1.3.2. Free from Google Code, iirc. Lots of options and levels. I was running the 7/18 firmware when I wrote this; reviews involve that firmware unless otherwise mentioned...Yz Free 1.4.2 - pretty vanilla, 'shake to roll' doesn't work, but game otherwise runs/plays fine; wants to go online to save scores, tho, which ain't happening on our hidden-SSID network.Bebbled 2.14 - works fine... slightly sluggish; doesn't seem the option of physical inverting the PDN to invert the playfield works, but there is an onscreen button to flip, so it's OK.Shoot U! Lite 1.3.5 - seemed to run very slowly for me... annoyed me a lot, but the idea is fun. Haven't tried it again since 7/18 firmware update.Frozen Bubble 1.6 - works fine, tho a bit slow. Definitely tests your ability to do tiny swipes with your fingers...Radiant Lite 2.8 - ran very, very slowly... pretty much unplayable at that speed, sadly. Haven't tried it again since 7/18 firmware update.Flight_Director_(LITE)_1.5.1 - has never ran for me. Crashes at startup. Haven't tried it again since 7/18 firmware update.Gem Magic Lite 1.1.19 - does not fun fullscreen or in landscape; sits flush-left onscreen, small size. Has screen glitching off to the right side off the playfield. The game's playfield is still clear, and the game is still playable, but you may not dig the display issues.Reversi 2.3.1 - Works. Nothing fancy. Computer knows about the corners, which keeps it slightly interesting...The Mario soundboard 1.8.4... not technically a game, but my 4yo son loves it.

That's about it... for now. I'm sure we'll try more (esp. now that yet another firmware (7/24) is out).I'd personally really appreciate it if people would include the versions of the games (free, paid, version number(s), etc), and what firmwares they've tried them on... The more info, the better...
