I just recently setup my MiSTer and I love it, I'm running it on a Dell Ultrasharp 2007FP at 1600x1200 (which poses another question I'll ask another time) and most games work great.
I do appreciate that this is open-source freeware so no I don't expect it to be perfect (although it damn near is from what I can tell).
However, one of my favourite games on the Atari800 XL was/is World Karate Championship but it doesn't seem to run correctly.
The first thing is that the colors are off, in the first scene the floor should be orange but is instead a sort of muddy green.
Secondly the screen seems to wrap around slightly on the left, which I can live with of course.
And finally there is no sound in-game at all, but it does have the title music on the initial screen which sounds fine.
One thing I have noticed is that running it in PAL mode make the colors correct but then it runs slower (of course) and there is still no sound.
Can anyone give me a hint on how this can be happening or is it a known problematic game?
All this aside I really am enjoying playing around with this core on the MiSTer, it's excellent!
