Setting a hidden dipswitch?

Hi All,

Does anyone know if it is possible to set a dip switch that is not available via the TAB menu? I'm experimenting with Exidy Venture and wanted to see if the switches listed in memory location 5103 can be set. (table mode switch, language switches, etc).

https://github.com/mamedev/mame/blob/ma ... /exidy.cpp

5103 R Interrupt Condition Latch
bit 0 LNG0 - supposedly a language DIP switch
bit 1 LNG1 - supposedly a language DIP switch
bit 2 different for each game, but generally a collision bit
bit 3 TABLE - supposedly a cocktail table DIP switch
bit 4 different for each game, but generally a collision bit
bit 5 coin 2 (must activate together with $5100 bit 0)
bit 6 coin 1 (must activate together with $5101 bit 7)
bit 7 L256 - VBlank?


I have been playing around with debug mode, but haven't been able to figure it out. Any tips?
