At first I was concerned about legal aspect of roms, then it turned into wanting the authentic game play; exact replica of sound, colour and speed. The last few years I've been playing NES on WII, PSX IMBNES, and PS2 emulators. Now, I'm thinking about buying the NES console with a hundred in one cartridge. How is the original Nintendo Entertainment System compared to the emulators I've played on? are the emulators roughly 100% the same as the original system + having save state feature & filters for hd tv thus making the emulators better than the NES?
