I tried searching where I usually search, but I can't seem to find a site where there are RTP like chipsets and I wouldn't post this if I didn't come to a dead end on my search. I'm horrible at search for things which is why I hope someone can help me with my search for a site of RTPs.
I would thinlk charas would have plenty of rtp chipsets, try looking there if you haven't already. Otherwise check the development and resource guide in the stickied section of "help and requests". You might find some good sites there.
