Audio Wave #3 is a compilation of some of the best MSX-Audio music made by DANDAN. Graphics by Spooky, code by Maggoo.

Note: Hold CTRL key down while booting your MSX. Drumkits loading seems to be inconsistent on some Emulators. Should be ok on a real machine.

It might not be the best demo on the MSX but it sure is the biggest one.

It took nearly 2 years to get this baby out. The result is a 3 disks wide monster which contains dozen of effects, 2 distinct menus, one game, one juke Box, one slide show, one hidden part, an overdose of egocentric scroll-text and great music from Dandan.

Little known facts: 

• The game within Metal Limit was supposed to be much more advanced than the release version, with enemies to fight, multiple graphic themes and many other neat things. Due to time constraint (read laziness) we had to leave it as it is.
• The hidden part can be reached by pressing IOD keys in the Lazy Bones menu. Hidden part contains a compilation of IOD demos published on various disk magazines.
• The lazy bone menu engine can also scroll up and down, we were too lazy to edit a larger area. Vscreen was largely inspired by this engine.
• The ending demo can only be reached by finishing the Metal Limit game or by launching "credits.ldr" on Disk3.

This unreleased demo features a VERY large scroller (128 pix high), and a lot of flashy colors. Ok, it's damn ugly.

The source code is provided with the demo. It's possible to add one extra set of color bars on MSX2 machines but it will flicker on TurboR machines. 

Music is compatible with MSX-Audio.

One of the first ASM intro of IOD (dated somewhere around 1991). Simple text scroller, big scrolling IOD logo, moving color bars and that's about it.
