Ugh, apparently the support was only for the Japanese release. Here's a list from VGLQ:
Final Fantasy 8, Ridge Racer Type 4 , CB: Warped (Japan Only), Gran Turismo 2, Street Fighter 3 Alpha, Theme Aquarium, Rival Schools 2, Wipeout 3, Pocket MooMoo, Pocket Dungeon, Go! Pirates, Poporo, IQ Final, and Countdown Vampires
Not sure if the GT2 & Wipeout 3 would be only in Japan releases like the Crash or if they are in the US version as well.

I just wish I could remember where I read/heard about the 3 US games that are the only ones to feature Pocket support. I could have sworn Crash was on that list. Oh well :/
