You actually play on a NES? Amazing. Mine quit working ages ago. I then purchased a "retro duo" which played the cartridges reliably, as well as SNES cartridges. But then I made the jump to HDTV and switched over to emulators with a pc hooked to the TV since the use of video filters (especially with SNES and N64 games) made these games look great on an HDTV whereas running a real NES console would either make it blurry or pixelated. SuperSAI2x for super nintendo games makes them look fantastic, *almost* like they are a modern game that was drawn to look retro.
