This is HUGE! Wow, this makes it so much simpler running DOS games. Set them up the way you want them, and then you've got a menu to run them....nice! I like being able to have a different mapper.txt file too based on the game. Some of those old DOS games don't let you reconfigure keys within the game so this will make it much easier to have a unique mapper.txt file for that game (especially useful for N800 users like me when I don't have my bluetooth keyboard handy).

I do have questions concerning the Basic and Advanced settings area. Are all those settings that are shown the settings that are in the default dosbox.conf file? Do I only have to enable the ones that I want to change from what is shown, or do I have to check the enable box to turn on the setting that is shown? I'm guessing I only need to check the enable box for changes, but I just wanted to be sure.

All in all, very nice. Thank you!!!
