    A few other things:

     

    1) The Ghostbusters symbol that you move around looks quite a bit better on the C64.

     

    2) I get what you're saying with it shouting "Ghostbusters" all the time, but Atari is also missing the laughing, which sounded great.

     

    3) Marshmallow Man at the end looks way better on the C64.

     

    All moot points for me though, since I like the SMS best (except where are the voices, arrgh!). :)

    You know the old LGR intro theme, Vaxeen 4u? That's a Pokey song, not a SID one. Also, I would consider a 4-bit volume control over the ADSR the SID because ADSR isn't too friendly with weird volume patterns. The SID also has a problem with resetting the ADSR, where it needs time to reset them, or else the note will cling onto the ADSR configuration of the last note. The route most composers have done was to make the entire speed of the piece slower to compensate for this. However, Rob actually doesn't reset the ADSR values for some instruments, because it isn't necessary for some of them to decay, so he left those instruments with a volume that stays the same. The fastest note that you can play (if you plan to reset the ADSR) is the intro of the song for Sanxion:

    Efficiency of instructions? The Z80 seems a lot less efficient. In fact, the A8s have more MIPS than the ZX Spectrum, multiplying 0.58 (0.58 MIPS @ 4 Mhz) by 0.875 (3.5 Mhz/4 Mhz), and I got about 0.5 MIPS. However, the Atari is actually faster at about 0.76 MIPS (0.43 MIPS x 1.79 Mhz), one and a half times the MIPS of the Spectrum, and using a 160 px mode can reduce the load on the CPU, right?

    Nice work! While you were working on that, I've made an optimized picture of a fan-made marquee online, slightly edited. What I've done to optimize the picture was to go into GIMP, set the color mode to the gtia palette, Ctrl+X an 8-pixel high strip, and paste it into another canvas, where I index it to a generated 8 color palette for each strip, Ctrl+X that, and paste it back into the picture, and I've repeated this process until I got to the bottom of the picture, and this was the result. I actually don't mind the stripes that much, though...
