This is not a slashvert, these solutions have been around for a long time, and as for the NES RGB board it's constantly sold out so they don't need our help on that. Actually this was posted on Kotaku a day ago and someone probably found it geekworthy, and it is. Getting 240p to display properly on HDTVs is a huge pain for retro gaming enthusiasts.
Use an emulator?! No thanks, that's like telling vinyl enthusiasts to get MP3s. Accuracy is important, and emulators are a mixed bag, and to ask someone who wants the original feel and the convenience of a console to fuck around with emulators is missing the point. Also try finsing a good legal Saturn emulator that works on Linux. Besides, there's nothing like using the original hardware, control pads, and media.
