Gnildir: Oh, the answer to your question on getting WarheadsSE to work on an x64 based system is with virtual windows (vmware) with xp installed inside of it. I am waiting for my new pc to be built so I can figure out how to get WarheadsSE to work on windows7 with an x64 system without going through all of that vmware crap.
Wishbone: The real answer (provided that you want the game to survive) is to update it so it works out of the box. If it's a hassle to get it to work, only a very small group of hardcore fans will ever play it.
If it's really free, you might want to consider releasing the source code. That will give others the opportunity to work on it, for instance in order to get it to run on Win7x64 unassisted.
I've been hassling the mod-makers over at DataRealms forever to make a "Scorched Tanks" clone for Cortex Command. I mean, I did pay for the "Support Data Realms" version of the game when it was first announced, and beyond a few cookie-cutter scenarios, progress hasn't developed much. If the guy in charge, Data, would focus on one thing at a time, instead of being distracted by every damn new shiny engine or physics tool that comes out, the game would probably be at least at a "v0.80" state or something. As it is, the majority of new content developed comes from the community. Unfortunately, nobody in the community can figure out how to get a "Turn based, stationary artillery game" to work from a "Real time strategy/Resource Management/Arcade" game.
BTW, Gnilder, your link to the latest installation executable doesn't work.
