They did try to rollout game boy Hamtaro games but it was too late in the game. The Hamtaro GBC game was so late in the cycle that the commercials emphasized GBA could play it too. There’s also a GBA game Ham-Ham Heartbreak which came out in America. To give an idea of how screwy the American release schedule was, CN did a marathon to promote Rainbow Rescue on August 21, 2004, even though it didn’t even end up meeting the July 4, 2004 release deadline! In fact it was never released here at all and to play it in English you’ll have to import it from the UK…
To be fair to Cardcaptors, it never aired at 6 am nationally. Kids WB as a standard Saturday morning block didn’t start until 8, and then later 7 AM with the Pillowhead Hour. Though some markets did shuffle things around especially for the Kids WB weekday airings which in Arizona were randomly interspersed with Fox Kids weekday lineup in the morning and afternoon on WB which aired both on channel 61. Cardcaptors actually often got pretty good slots, and lasted a year or two, which is a lot longer than Escaflowne’s month or two. If you look at the schedules up through September 2001, it took slots from big WB comedies like Pinky and the Brain and DCAU shows like Batman and Superman. Cardcaptors regularly aired just next to Pokemon. They didn’t really deathslot it until they used Kids WB Toonami on weekday afternoons to quickly rush through season 2, after Yu-Gi-Oh took its slot on September 29. If you look at the improvised post 9/11 schedules from 9/15 and 9/22, the Mummy, Nightmare Room, and Yu-Gi-Oh were all delayed two weeks, due to themes of Egypt and horror being too sensitive for the immediate post 9/11 climate. During the Super Stuffed Saturdays used to kill time for a couple weeks, they gave Cardcaptors a full hour of premieres both weeks. I recall CC was also used on CN’s Kids WB spotlight slot on Friday nights next to CCF, Toonami, and Samurai Jack, to kill a week before the Mummy and Yu-Gi-Oh! could premiere. They tried their hardest to make it a hit, making a soundtrack, heavily re-ordering and re-writing it, but it just didn’t work after it had to compete with Yu-Gi-Oh and other new shows. More hardcore anime also hit Toonami during CC’s run: Gundam Wing, Tenchi, Outlaw Star, Mobile Suit Gundam, 08th MS were all competing with Kids WB, offering more authentic Japanese experiences complete with Japanese music and names, making CC seem like the hackdub it is now known as. By September 2001, Cowboy Bebop was now premiering on AS with a TV-14 rating. The anime market began moving more to target older audiences and primarily males,… so Cardcaptors’ run on CN in 2001 was only the spotlight slot and three weeks on Toonami, to build hype for Season 2 on Kids WB.
