|Tester||ketburai||View Status||Public||Platform||MAME (Official Binary)|
|Version||0.169||Fixed in Version||0.180||Build||Normal|
|Summary||06118: taitofx1, vspsx: "Unknown" dipswitches 3 and 4 on PlayStation-based arcade hardware|
Seems these do different things for each brand. So far I see:
-Taito: Not sure what dip 3 does yet, but dip 4 brings the game's test menu up on boot.
-Video System: Dip 3 brings up the game's test menu on boot, dip 4 purges nvram completely and prevents further saving (the test menu notes status of this at the bottom).
I imagine every brand uses one of them for game test menus.
edit: Sorry about that, for some reason I completely missed the DIP/Input category.

Thanks for the report! At line 2692 of drivers/zn.c there's a note about this: PORT_DIPUNKNOWN_DIPLOC( 0x08, 0x08, "S551:4" ) // game testmode in some games
So it probably should be researched for every game and eventually correctly identified/differentiated in the source.
