help with mapping keys

[Rawker]

i can't for the life of me figure out how to map keys with command line mame, i have a ipac4 and needed to use a modified configuration because player 3 seemed to be causing problems with whatever the default buttons are (alt, shift, tab, or something stupid). I did it before but i'm not sure if i used a program to set them up or if i did them manually. i think i could use the tab menu before but for some reason tab doesn't work in mame.

If tab's not working, the easiest thing to do is delete cfg/default.cfg.  The other choice is to edit that file in any text editor:  change the UI_CONFIGURE defseq to "KEYCODE_TAB NOT KEYCODE_LALT NOT KEYCODE_RALT" and save.

Once you get tab working again, you can edit the inputs as you had before (tab whil in mame).  Or you can hand edit cfg/default.cfg.  Or best, copy that file to the ctrlr folder and set "ctrlr default" (or if you rename the file, the name you change it to).

thanks man that did the trick, i don't know how (or why) i changed the menu button and finding that config file amongst all the others really helps if you know what your looking for.
