JB-3000 Dip Switch Settings
Below are the dip-switch found in MAME for this JB-3000 romset.
WARNING: While MAME has very useful dip switch settings, many of them are listed in reverse order (ie: the settings are really for switches 8 down to 1 instead of 1 up to 8, or vice versa, or on really should be off and off really show be on. If you compare what is shown on the chart to the switch settings you already know, you should be able to figure it out. When available, please see manual)
