The rather diffeent PSP TV Adapter posted by Lik Sang the other day how has an official website, heres what they posted:
<blockquote>PSPonTV is manufactured by the same people that brought you GBATV ™ ! We made the first GBA2TV product and also we made the GBA Halo back light, which demonstrates our commitment to quality and innovation. Regarding high tech electronics manufacturing, we have millions of units sold vs 0 units sold from our competition. You can trust our quality!
Other competing products "claim" they are available, or will be soon, but they have absolutely no proof of existence other than some photo still shots on a TV Screen (as of Oct 2005). We have video proof that PSP on TV works great, even before the final tweaking has been done!</blockquote>
