well for no reason whatsoever my C64c decided to stop outputting video. seeing as i had a C128 laying around i decided to just hook that up in its place which has prompted me to ask a few questions

1) the C128 has an output for RGB video. i'm guessing this won't work in C64 mode meaning i won't be able to play my C64 games in RGB and just have to stick with
"commodore video (S-video)"

2) things i've read say the C128 has "99.8%" compatibility with the C64. anyone know specificly what programs/games are the .2% that won't work?

3) any games written specificly to take advantage of the C128's extra power worth getting? only thing i can think of is Ultima underworld has better sound? but i figure these games are better under DOS with a decent sound card anyways
