Hello, people! Once again, sorry for the delay responding. I'm as busy as ever.

MrAlextov: There is a scale feature, but it's limited and doesn't allow Jazz's 320x200 resolution to be scaled all the way up to 1920x1080. Your monitor should support lower resolutions, though - have you tried full-screen mode?

Tecman: Thanks! The configuration problem is wierd - could you send me a sample broken config file?

Yeah, the scaling algorithm is Scale2x. I didn't add it, and looking into it, it doesn't support plain scaling (what you see isn't actually a post-processing step, but how the scaling itself works).

I've fixed the pushing-down-from-magnets bug in the latest release. The rest are on the to-do list

I'm planning to move to Git or Mercurial fairly soon (and away from SourceForge - which repo hosting services are good nowadays?), but in the meantime you can just submit patches. Or, if you have a SourceForge account and promise not to trash the repo, I can give you access.
