Space Invaders Sound on C64

[Mr SQL]

 

These Space Invaders soundtracks are written for the Atari 2600 TIA chip but can be played on the Commodore 64 SID via emulation.

 

When played through the SID distinctly different soundscapes emerge.

Try them on the Commodore 64:

spcinvsids.D64

 

Use the loader program on the D64:
load"loader",8
run

 

Here are the Atari 2600 ROM binaries to compare:

NewSpaceInvaders.bin  NewSpaceInvadersAlt.bin

 

The Tracker prototype written in Commodore BASIC is included on the D64 image and illustrates streaming a TIA chiptune to the SID.

I used a 6581 NTSC SID for development. Filter effects may vary.
