For the Atari 2600 ROMs go to the homepage and get them there. They will be moved later. For the emulator,
go to zophar.net and get z26. There's a trick to use this. Make a shortcut of the z26.exe program
(the one with the white box) and put it on your desktop. Then go to your ROM's folder and drop the games into the shortcut.
The emulation is almost perfect. If there is something wrong you can try another emulator, but i haven't been able
to get some of them to work.
