Remove that link, or be banned. Released or not, it's still owned by someone. Ask Nintendo. Did they ever release Starfox 2 (it was a SNES game that was never released)? No, they didn't. And yet, they still own it. In other words, get ready to be banned... Trust me, this site isn't very lenient in that regard. And I don't blame them. On top of that, what's to stop someone from using your link to find something else, that is less legal than this Half-Life image is (not saying it's legal, but that if it has any legality at all, the other stuff must be less)? Sorry, but your days are numbered.
Also, did you even bother looking at Chankast at all? When was the last time it was updated? 2 years ago? More? All I know is that it wasn't recently, and it won't be anytime soon.
On top of that, Half-Life is, I'm pretty sure, a Windows CE game (this would explain why it was easy to port it to the Dreamcast, after all). Chankast has no support, at all, for anything that uses Windows CE stuff. In other words, it's not going to happen.
As I see it, you've got 3 strikes already, and all in one post. Nice job. Linking to illegal material, asking for an update (when it hasn't been touched in years) and asking for support for something that isn't going to see the light of day for a long time to come (excluding the fact that Chankast hasn't been touched in years).
Good luck with all that. I suggest you do a little more research next time.
Last, I'm up too late. I know that's a terrible excuse, but I'm hoping that my comment here (the post I've written) will help you understand that it's very wise to look before you leap, figuratively speaking. It seems to me, that you leaped, and didn't look. Think (more than) twice when saying something, and it will benefit you greatly. Not just here, but in life in general. Trust me, doing that will get you far.
Hopefully you at least get rid of that link before a mod sees it. Mouser X over and out.
