I would think pretty much the same reasons as ever for using an emulator versus native(ish) hardware: you really need/want save states and are fine with compromising on accuracy. No shame there btw, I know I don't have enough time to play every game I want to, so save states and rewind are great features in my book. Otoh, being able to play stuff like Kirby's DL3 with proper transparency effects is super cool. Congrats on the Super NT, they look sweeeeeet.
Thanks. I probably won't mind the emu quality as much as some hardcore purists (I've been fine with the emulators on Wii but that's also on CRT).
I'm excited about the Super NT but, there's just that nostalgia of the look of the hardware and emu menus that are so nice that makes it hard to say no to getting a SNES CM.
