Somewhat attractive so far...

 Not a lot of time so minimal progress, but something to show for it.

So far the code has been straightforward to transcode. I think that'll be the case for quite a while yet, as I work through the attract mode scripts and underlying functionality.

I'm not quite sure what the 'corruption' is on some of the tiles. Right now it's irrelevant to the process.

EDIT: I've just noticed a few issues with the above, namely the bottom half of the display is not in colour. I'll look into that. I also notice on MAME that '1UP' and the score & high score are displayed, even before the attract mode starts. I'll have to look into that as well!
