Here is a list of all the video drivers you can pass as a parameter to the '-vdriver' option: auto, safe, vga, modex, vesa2l, vesa3, vbeaf Here is a list of all the joystick drivers you can pass as a parameter to the '-joy' option: auto, none, standard, 2pads, 4button, 6button, 8button, fspro, wingex, sidewinder, gamepadpro, grip, grip4, sneslpt1, sneslpt2, sneslpt3, psxlpt1, psxlpt2, psxlpt3, n64lpt1, n64lpt2, n64lpt3, db9lpt1, db9lpt2, db9lpt3, tglpt1, tglpt2, tglpt3, wingwar, segaisa, segapci, segapci2 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.
