It's enough to make you seethe with jealousy. About three-quarters of the way through the mind-bogglingly long scrolly that features in this demo, the author casually admits it's his first all machine-code program. Talented swine. (Ahem.) Bateria (good name, eh? Is it some highly obscure foreign word? Did they mean to write Bacteria? Hours of fun!) is a three-part demo, the first part of which is a tidy intro, and the last pert of which is a load of programming credits. The interesting bit is Part Two - a large sine-wave scrolly wibbling above a graphic of a stereo tape deck.

But this tape deck is more than just a pretty picture (Dramatic, eh?). By using a couple of control keys, you can fast-forward and rewind through the various music tracks available. Ha ha! (Please yourselves.)

The songs are all a bit poor. Except for one very near the end of the tape - but that's been ripped from a game, so we'll gloss over it. (Hem hem.) All in all, a very competent piece of coding, but a rather boring demo.
