I guess this is due to the problems that Bubble Bobble recordings have with frame skipping ( see Angry's guide to recording troubles at http://www.primenet.com/~greggg/marp/inp-prob.html ).

<PRE>
In Bobble Bobble, the frameskip setting used during
recording must be used during playback.
<p>
When making a recording with thise game, it is important
that you don't *tweak* the frameskip setting during your
game or the playback will fail when it reaches that point
of the game. You should set the frameskip before starting
the emulation.
</PRE>
Since MAME these days automatically frame skips when the going gets tough, this will probably affect most bublbobl recordings. To prevent MAME from autoframeskipping, you can give it the option:
<PRE>
-frameskip 0
</PRE>
when you start it, or more permanently, you can put
<PRE>
frameskip = 0
</PRE>
in your mame.cfg (you probably already have a mame.cfg wherever your mame.exe file is, and it probably already has a 'frameskip =' line in it - just change that line).
<p>
The same problem with frameskipping is also reported for other games on Angry's page - particularly the 1983/4 Sega games (Flicky, et al).
<p>
Let's be careful out there.
