Gameboy Color
Neo Geo
Atari Jaguar

I'd appreciate any help I can get guys.....new to the community but passionate about games.....thanks so much

You need to define best.

most accurate
fastest
highest compatibility
Easiest to use.

For example nes:
bnes most accurate
jnes easiest to use
fastest most all are fast
fwNES most compatible

I'd say most user friendly and easiest to use.....newest....

Then just go here. We have done this for you over the years. Its very up to date IMO.

Wow thanks so much! I really appreciate it!

I don't see Sega CD, Atari 2600/7800, Atari Lynx or Atari Jaguar anywhere.....any ideas where those can be found? Again thanks so much....this is awesome.

Or sorry , Atari threatened us to take atari emulation down. We can no longer even talk about it here. All sega emulators also do sega cd.

woops sorry.....rookie here
