Does anyone know how to access the DIP SWITCHES on this arcade game? are they hard switches inside the game or are they electronic switches accessed by code?

please advise.

DIP switches are hardware switches.

Emulator presumably could include access to such on software if you're playing it via such tho, but might not have included the capability for it.

Yes DIPs are hardware, but some coin-ops accomplished the same functionality in software only. I've seen setup screens in coin-ops that actually use the term "DIP SWITCHES" right there on the screen when the unit has none. Generally accessing these screens is not complicated, just obscure (usually less complicated than the Zelda save code and nothing approaching the complexity of the Konami code). This is to keep just any customer for changing settings in the arcade. They could, theoretically, change them to something that let them continuously play the game from opening to closing on a single quarter provided they didn't make any major game ending mistakes while playing. This is not good for business as the arcade owner would probably rather the machine be taking quarters all day long (despite there being valid business strategies where this would not affect profits and actually increase them if planed carefully). Some are annoyingly obscure and are, in practice, hardware switches because of activating them with hardware input, like hold down fire when resting to toggle 3 or 5 lives and hold down jump to toggle extra lives every 5,000 points or not. There may also be a hidden button involved found outside or inside the unit. Activating these setup screens (or 'software switches'), in nearly every case, is detailed in the manual that comes with the game. You probably have to hold a button or hold a buttons combo during boot, or press a button during a window of opportunity during boot Barring that, a 3rd party technical manual would say how. Your best bet would be to ask a coin-op vender. They can direct you to the proper manual or their guy/gal might know from experience. If there are not stickers with the vender's phone number and/or address on the machines at your local arcade, then ask the manager who their vender is, or in some cases who their repair guy/gal is (if they don't buy/rent through a vendor).

OH, ALMOST FORGOT! There may also be jumper pins inside the machine that do what DIP switches do. Pins that stick up from the circuit board that have one or more removable jumpers on them that can be used to connect adjacent pins. Don't adjust these without knowing what they do. You might send 12 volts into a circuit intended for 1.2 volts (*sizzle*, *poof*, *smoke* your coin-op is now a brick with a joystick and buttons installed)
