Correct, @mitu , I created a separate system that lists the conf files:
<system>
<name>p2000t</name>
<fullname>Philips P2000</fullname>
<path>/home/pi/RetroPie/roms/p2000t</path>
<extension>.conf .CONF</extension>
<command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 _SYS_ p2000t %ROM%</command>
<platform>p2000t</platform>
<theme>p2000t</theme>
</system>
Runcommand looked good:
Parameters:

fluidsynth: warning: Requested a period size of 64, got 480 instead

I am happy to investigate more if it helps the community. If we collectively believe this is a problem with a 20-year old emulator, I am also content to call this one good enough and run without a joystick. :)
