Interesting, because in the techincal forum, Ginny's last replay more explained what problem she was having, and then she was like "...never mind, I fixed it thanks to Crono" or something along those lines.

Well in the actual game the sound quality isn't what it should be. Besides that I can play it, but as far as my other two affected games are concerned, I can play them at all (I can't look at a screen of flashing horizontal coloured lines!).

You can go to the technical forum and read under "Jazz 2 Direct X problems". It seems like it's the problem I'm having too in TSF.
