Have you guys ever heard of the PC-FX Anime Festival? It took place in June 1996, and apparently like 24,000 people showed up to it over a two day period. A couple of ancient internet logs describe live music and cosplay, and priority given to members of the PC-FX fan club.
Remember that crazy
Supergrafx Power Console prototype that ccovell posted as part of a prank? It turns out they auctioned off a real one at this show.
The September 1996 issue of PC Engine Fan magazine came with a CD, and on that CD is a 20 minute long "radio show" accompanied by still pictures, hosted in the beginning by the girl who voiced Rolfee. You can watch and listen to it
here. It starts with her reading flattering fan letters and promoting Rolfee CDs. She thanks everyone for sending lots of postcards, and invites them to write more. Then she starts an interview with Rolfee...literally talking to herself. She later reads "Rolfee's diary".
A voice actress from Fire Woman Matoigumi also comes on and talks about games and audio-dramas and stuff. Nothing too fascinating.
But then at about 21:00 minutes into the video, they talk about the PC-FX Anime Festival, with live video footage included. You can see a live performance from the Angelique voice cast. The Rolfee girl is there, too. An actress from the game Hatsukoi Monogatari sings a song karaoke style. Rolfee girl says that games are for sale, and attendees can see demos of games in development. There's even a "Princess Rolfee Corner" where you can buy pens and phone cards, and enter to win your very own t-shirt and custom Rolfee "Staff" sweater. You'll see lots of stuff up for raffle through the magazine, too.
By the way, did you know that there was also a PC-FX-centered anime-game radio show (as in actual broadcast radio)? It only ran for a few months in late 1996, but it seems it was tied in with these PC-FX magazine CD audio promotions. I'll see if I can find out any more about it, but it's pretty slim pickings out there.
