Topic: How to enter the service mode in Defender & Robotron 2084 & Sinistar

[ClessxAlghazanth]

As the title says 

I'd like to get into the service menu and change difficulty & lives in these games , in order to progress more than 5 rounds in Robotron , and to last more than 3 minutes in Defender & Sinistar 

Been looking around on the net with no avail

These games don't seem to have usual dipswitch settings

Any ideas ?

Best regards

The Williams games have a weird way of going into service mode:
after the game boots, press Advance (mapped in inputs/F5), and you have to keep pressing advance to go through all of the tests and sooner or later, you'll hit a games setting screen where settings can be changed.

Instead of changing the settings.. I really suggest practicing more using the defaults, or even use savestates to help practice - it's a really fun way of practicing.  I'll explain:
find 2(or 3) unused buttons on your controller, for example, the shoulder/trigger buttons.  Map the "System load state" "... Save state" and "undo state" to those 3 buttons, and hit the one you've mapped to savestate every time you make good progress in the game.  If you die, hit the load state button    The undo button will become necessary if "save state" was used at the wrong time.

Good luck!

Thanks a ton , dink ! 

I've been getting better slowly at Robotron and Defender , even if just a little bit , using the save states better

But Sinistar seems to be a different kind of beast

Great
Sinistar is very difficult, I can't get too far in the game, but I still play it often.  It seems like the second stage is either really hard, or a little bit more difficult than the first stage.  though, I haven't figured out what triggers the difference yet.
