I have a Duo-R that I got from doujindance that is RGB modded, but I have never used it. Not even sure how to really. Basically what connector to use and all.
Shame on you! I've always wanted one of his units but am not paying his current asking price.
If you have a SCART TV the connection is quite simple, but I'm assuming that you don't so your next best bet would be to use an encoder, such as the CSY-2100, to convert from RGB SCART to Component.
