ZTron2600 is a frontend for the Atari 2600 emulator z26. The Main feature I like about this frontend is 7-zip support. If your like me and use GoodMerge on your Rom sets this is a must have. Other features include control and video settings.

Note: the author mixed up the directories. Instead of setting the z26 path to the z26 directory and setting the roms path to roms directory simply reverse them.
