The loss of light gun gaming is one of my major gripes with the "upgrade" to LCD TVs and it's a real shame.
That being said, I don't mind using the Wiimote for these types of games and although the accuracy is not the same as the light gun, at least the general feel is there.
Regarding scaling, I like the sharpness that HQ2x brings, I just wish there was a filter that would give nice smooth edges but mix the colours together, similarly to how CRT would have done.
Agreed. Some games that feature large areas of solid color look great when upscaled but others miss that blending effect that you get with a crt. Great comment!
