Incorrect behaviour

Games having a service="yes" in the input tag of the XML, should have a working service menu accessable by pressing F2 in MAME.

But many games having this value will not run any service menu when pressing F2.

Examples that work:

• 1944
• aburner2
• astorm
• ...

Examples that don't work (nothing happens when pressing F2 but they have service="yes"):

• gtmr
• 720
• ...

Expected behaviour

I expect each game having service="yes" to run a service menu when pressing F2. But this is not true and I have no idea what the reason could be.

Steps to reproduce

1. Run a game that has service="yes" in the input tag of the XML
2. Press F2 to run the service menu
3. See that not all games display the service menu, even when they have service="yes"

JJ, the one in atarisy2.cpp was a bug and it's fixed.
The one in kaneko16.cpp, who knows what it's for. According to service mode (use the dipsw menu) it's a separate TEST button.

So as I understand correcty: each game will have different behavior when pressing F2 and some games first need to have a dipswitch enabled for service mode to work?

Thanks for fixing the bug so fast!
