I bought a Bust a move again loose cart on ebay, All the roms and the label match MVS Sans. Two of the roms look newer than the others, but they do have the proper markings on them. when I fire it up there are grey side bars on the picture that occasionally change colors. Is this a boot? the vids on youtube don't have these bars. It could be I need to adjust the horizontal size on my monitor, but these are the same settings I use for all my other mvs stuff, and there are no bars on those. I want to leave positive feedback for this guy because he has been great to deal with, but I just want to make sure. Thanks guys.
