Pausing in Galaga

[mcr]

Archived from groups: alt.games.mame (More info?)

Hi,
In Galaga I noticed when I paused it, the playfield continues to scroll.
So I was wondering, what is 'paused' when MAME is? I assumed the
entire core was 'frozen' when the pause button was pressed but obviously
this is not the case.

I am just curious to the mechanics of the pause button. Anybody know?

When I pause in Galaga everything is paused. The playfield does not scroll.
I'm running MAME32 v0.88 with rom Galaga (NAMCO rev. B).

When I pause Galaga.zip (Namco Version) running MAME32 Plus 0.100, the
playfield does indeed keep scrolling when I pause it, but it's a
static background that scrolls, not the "twinkling" one that you see
during unpaused play.

MCR <mark.coleman10@ntlworld.com> gyrated his joystick in a pattern that
spelled out:

This is a recent problem that should be checked for more severe behavior on
other multi-cpu games???

I am thinking that it would make some kind of sense broadcast the pause
request to each of the subsystems drivers (Main CPU, etc.). If galaga
actually had 3 Z80s, it would seem that at least one of them is not getting
the request to pause.

Of course, maybe I am way off base here...

Bug introduced by Aaron's UI handling changes[1], fixed in u1 I think.
