I found some sheet music from Monkey Island 2 that I have been converting to a format playable by our music chip by entering it into the MOD2PSG2 tracker. I think the result is pretty good (although far from the original) so I decided to turn it into a slideshow demo with screenshots from the PC game.
There are 3 versions of the demo:
monkey8.bin is a 512K cartridge image for the original 9918A video chip. The image quality is pretty bad, but at least you have something to watch while listening to the music. The cart requires 32K RAM because the music player needs it, and I was too lazy to try to make it run on an unexpanded console.
f18a-monkey8.bin is a 512K cartridge image for use with the F18A video chip. This is using Tursi's routine to display images with a new color palette for every scanline. The image quality is a lot better than for the 9918A, but there's still a long way to VGA. This runs fine in the latest version of Classic99, but JS99er.net is lagging (unless you have a faster computer than me) as is not recommended. The sound quality is best, of course, on real hardware.
monkey.dsk contains an E/A#5 file with just the music and a single image.Try this if you want to hear the music, but cannot use one of the other options. We need The FinalGROM 99!
I have also attached the music if you want to play around with the tracker.
