I've seen all episodes from 309 up to 548 in japanese with german subs, I couldn't find the earlier episodes in japanese though, the german ones suck because they're censored and totally butchered. Though I've seen a few ones when I was younger. I wanted to import the DVD's from Japan but damn are those fucking expensive.
Also I've seen 12 movies. Too bad I can't find numero #13 on the net anyhwere. Seems like subbing comes along slowly.
In the Manga I'm at #24 right now, the current count is somewhere around 65.
The american names totally bother me. XD
In Germany and Japan, the names are:
Jimmy Kudo = Shinichi Kudo
Richard Moore = Kogoro Mori
Rachel Moore = Ran Mori
Dunno about the rest.
It's certainly my most favorite Anime because it was the first one I've ever seen in my life and finally took it up again not too long ago only to realize that I missed like 400 episodes. Gōshō Aoyama surely does a good job up to today.
