So spoke with the people making and selling this and it turns-out the tech is using Field-Scaling, so there is no loss of vertical resolution on 480i. What the box does is simply double one 240p field (or both, if in 480i) so you wind with either:
- one 480p frame for each 240p frame if coming from a 240p output,
- or 2 480p frames for each 240p field stacked at twice the refresh-rate.
Now if you are in say a 3D Driving game with lots of vertical motion you won't be getting really 480 detail, because the original interlaced-frame didn't have it, BUT for more horizontal or static pictures (like say Resident Evil 2 on N64 running at 480i), you are indeed getting a sharper picture and all the resolution the original signal had to offer.
Further the "Smoothing" function interpolates in between frames (line-average antialiasing), so you wind up getting a more solid image in 480i games after processing than you would have had even on the original with less vertical resolution loss, and comb-tooth ege aliasing detail-loss.
This is the box to get. If he goes on to make one with scaling and scanlines, Framemeister (Micomsoft) might be out of business.

WOW

Input Composite, S-Video or Component from any non-ED/HD device and output to HDMI without latency (roughly 1 frame out of every 60).
While there are obviously other niceties we could want, for the money this is unbeatable. The creator is planning to keep working on this too eventually adding support for scanlines and possibly scaling.
He currently also has a breakout "hat" of similar configuration for people using Raspberry Pi for emulation that can output to Composite, S-Video, Component and VGA - providing high-quality arcade simulation using readily-available CRT devices.
