Re: Tempest

you can get instructions for the hack as well as the rom images at

http://www.paladingrp.com/brianb/board_hacks/tempest.html

admittedly the instructions kind of suck as it's the first I ever did/wrote up.
I was considering re-writing it up like one of my latest with pics etc
(http://www.paladingrp.com/brianb/board_hacks/centipede/centipede-single-rom.html)
which would make it much more easy to follow but wasn't sure there was
any interest in it so never invested the time.

hobbyroms is great for burning roms and I'd imagine they'd do it, but
if not I'd be willing to burn you a ROM if you are not in a rush. (my
eprom burner only works in XP and I don't have an XP machine around
anymore as I just upgraded, haven't tried seeing if the burning works
reliably via a virtual machine yet/USB passthrough)
