The reason that the config file was moved is for compatibility with Vista/Win 7. The rest of what you want can easily be done by specifying the config file used on launch with the -conf switch and the use of the autoexec section of the dosbox.conf. The DOSBox README has all of the information on how to do this.

i'm very sorry.

No reason to be sorry. It is just information that you can use.

1. like the dosbox 0.72 , set the config file back to the install directory.

Nope.

2. create a dosbox virtual command, make sure this new command can load the current directory (that dosbox.exe starts) to C:.

Already included.
Also mounting to the root of a drive letter is a bad idea.

so, i want to make a simple zip files including dosbox and the games.if the above two is done, i can take this zip files everywhere!

Frontends. Look into them.

thanks very much, who can tellme where i can download the whole source code of dosbox. maybe i can try to modify it myself.

Try the magical sourceforge website.

oh, i forgot to say, can you add a new feature that terminate itself automatically when the loading game is over?

No need, it's already included.

Install Dosbox, then copy the app directory somewhere. Put dosbox.conf into that directory (dosbox will use that). Then uninstall dosbox. Then edit dosbox.conf in your new "portable" dosbox directory and add "mount c ." to the autoexec section. Now you can put any game (e.g., "yourgame") under the dosbox directory and when you launch dosbox, it will be c:\yourgame. ZIP that directory and you can take it anywhere.

..or take this and extract just the DOSBox-0.73 folder.
