Hi.

I tried installing it on my new-ish HP craptop (not too bad spec wise, just don't like HP). Anyway....I tried installing worms yesterday and after having trouble getting the installer to launch and using an installer I got off another thread, I got it to install. When I launch to the menu it's black and white. I tried the menu palette tweak and tried it, hoping it was what I needed, but it wasn't. When I tried to launch the game, I just saw a swirl/messed up lines in black and white. I tried looking for a solution on the forum and failed. Anyone know what it might be?

edit: that was the problem yesterday......right now it's now playing fine but just in black and white.

Is it on version 3.6.31.0 right now? Post the palette.log here.

hm, weird. Sorry, but I cannot help you on this subject :(

Similar to your problem I think. Try pressing Shift+Pause during game.
Did you try updating video drivers?
the last solution I know (but it's not the best, and it will only work in-game), is installing Project X. it enables 32-bit color ingame, so the issue during the match should be fixed. other than that I don't know, sorry...
