emulate my games so I have all the consoles (excluding, xbox, 360 and PS3) on my PC, that perform better and look better. Using a 360 pad.
I agree 100%(apart from the pad). You can even play Golden Axe 2 player on the Megadrive or Arcade for example. Considering the games were specifically designed for the pads that came with the consoles(sensitivity, weight of buttons, small things that make a big difference).
The Megadrive for example. If you play the emulated copy of Revenge of Shinobi it is much harder to double jump which makes later levels just about impossible as they were extremely difficult even with the original pad(never beat the final boss even when I was that good at the game I got to him within 40mins with all my lives).
I myself have most consoles worth collecting, I don't buy anything before the Megadrive/SNES era because I would never use them.
I sometimes hookup my SNES or Megadrive on my spare TV(I have my Xbox(original), PS2 and Gamecube permanently hooked up). as I like giving them a good test out. I'm an avid collector of Japanese Megadrive games as it happens, the artwork is beautiful compared to the crappy Western stuff (most of the time).
Emulators are brilliant, simply for convenience.
Consoles are trying to emulate the PC emulate world, some are even using modified versions of freeware emulators.
Another area where the PC will never be beat in, without a massive premium that is.
