Awesome update, no9 – especially the samples used in Desert Dream :great

I've tried to hunt them before down but with no luck.

A little contribute, anyway this is the "original" song for the game "Bomber Bob", an italian game, so an italian singer :agree

Speaking of DD. There are two Protracker modules by Deejay "Tales 2.9012182" and "I hate marshmallows" composed/released in 1990 and 1991. They both contain sounds that ended up as a signature sound for Desert Dream demo.

"Tales 2.9012182"

"I hate marshmallows"

"Tales 2.9012182" tune have original sample names left and there is one "ST-45:majchoir4.u110" which suggest that it was sampled from Roland U-110 module. Which leads us to this patch (6:00):
