Background: Some games have dipswitches that mean one thing if other switches are set one way, and something else if the others are set differently. Mame semi-recently came out with conditional dipswitches so the names change to match the differences. Example: xevious (galaga.c); if the number of players per credit is set to 5 (vs 1, 2, or 3), it's harder to get extra men, and the dipswitch that sets the extra point levels changes (10k 50k vs 10k 40k, etc) in mame's dipswitch menu.
Currently, the only way this is seen in listxml is that that dipswitch has has two defaults, lots of posibilities, and (in this case) two "none" options. I can search the source, but I get the driver files and line numbers where the dipswitches are declared, but these input declarations can cover clones or not, and other games or not, or be a "common" declaration than different games modify differently (meaning the conditional might be left in for some games, modified for others, or removed by even others).
Is it possible to make a list of all the games that have conditional dipswitches? (That's easier than going through the source?)
