The easiest, instruments to make....
Try to make all of those others yourself

except for plogue

You can emulate piano and flute with pulse waveform with proper envelope and good tracking, really add noise when necessary. And all percussions are about quick pitchbending down. Hihats and Crashes with noise channel with shape command etc.

So glad there's no VSTs in chiptune.

that huoratron part rocks!!!  I need to do a gameboy cover of that song for my LSDJ master of arts.

try lsdjguides youtube channel

* a tom - Tom sample
* an organ chord instrument - organ sample
* a muted guitar - guitar sample
* a piano - piano sample
* a flute - flute sample
* a lead with vocal-y sound - pw1 or sample
* a 2nd, higher lead which can be controlled separately pw2

damn justice really sucks

how about don't use lsdj at all problem solved

@ eme7h: Your math professor would be cooler if he used LSDJ to show you that.

@ Lavar: I strongly recommend experimenting to try and find your own unique sounds and instruments for use with the cover. If not, then consider loading up some samples of those instruments into the WAV channel as kits, and go from there.

Tom
NOISE Ch
ENVELOPE C1
SHAPE EF

But yes, try to figure out how sound works and the numbers behind it, my math professor uses Super Collider to show us that.

With the risk of sounding rude, have you tried creating your own sounds? Trying to experiment your way to the sounds you want is the to learn how to use a program. I wouldn't mind if you asked for a one or two sounds, but what you're asking for is to basically get a preset for every instrument you need.

What makes a gameboy cover interesting is how people invent sounds to work around the limitations, and make it recognizable, but usually dissimilar sounding.

see http://www.youtube.com/watch?v=myohIob9lgk for a great example.
