Thanks. I was determined to make the 5200 games more "plug -n- play" so to speak. Because I figured most "sets" out there contain the 5200 ROMs anyways. It actually ended up increasing my appreciation for the 5200. Before that I did not really care about the "analog" sticks. Only thing that might annoy some people is the "centering" junk in 5200 games. For example in Ms. Pacman you have to at least move the stick in all four directions to get complete control. Plus fixing the "trackball mode" stuff created some other annoyances, but surprisingly the original 5200 did those things as well.
The way I did autoconfig is not exactly the best way but I have not really thought of a better just yet. Maybe I'll just make up something similar to the cheat code custom file. I just didn't want to hold up the release. I would have ended up "tweaking" the thing forever.
I really need to put together some type of (Atari 8-bit computer cartridge set that consists of it's cartridges and the XEG cartridges). The XEG was a console style system Atari released later on that consisted of machine, detachable keyboard, used standard atari 8-bit computer cart slots and controllers.
