You can put any commandline option into a plain text file which should
|
|
be called "gen.cfg". Put one option per line, please. Command line options
|
|
will override anything in the configuration file.
|
|
|
|
Currently the zip loading code can manage a zipfile where the game
|
|
image is the first thing in it. If you try to open a huge archive of
|
|
games, only the first will be played.
