Hey all!
I ran into Launchbox while looking for a good front-end to my emulators. Great program! I'm a big fan.
Of possible interest, I have wrote some new 2600 homebrew games.
They are all on AtariAge. The links are:

There are multiple versions, just download the latest. Some of these are still work in progress, but all of them work fine.
