I have my Trident running Dick's new rules and sounds with a nano and a wav trigger. I can attest that you will want to do this to any machine that people have already "hacked." Dick's Blackjack update looks killer and makes me wish I still had mine.
These mods are so fun and groovy and dual bootable!

I don't have a Flash Gordon, but I have built Roy's board and run and (slightly) messed with Dick's code on my Trident. I think i might be up for building a few boards and compiling someone else's code onto the arduino. I've already gone thru most all of the issues and figured things out with mine with Dick's help.

pm me and mebbe we'll figger out a deal
