the real trick is making/finding the right receiver for your PC.
if you (still) have a comport it's easy,
i never tried the usb version myself.
you can make a receiver yourself, buy one ready made, or maybe i could arrange one for you.
it will be far cheaper then a konami soundsystem.
they are very hard to get, specially with combatdigiQ soundcards.
as for the batteries, i don't know at the moment.
single 1/4 AAA cell's are more available/cheaper than ready made cellpack's
like the VS replacements.
but it's more work to put it all together.
rody mentioned he ordered some in the nice pix thread, maybe he can tell you more about were you can buy some.
