Track 10 is my favourite from the set. Ares64 was kind enough to provide me with the original PCM samples he used for this soundtrack, and after some fiddling around with Deflemask and its raw PCM capabilities (and reporting bugs in the process), I came up with this. :)
Note that not every player supports the "hack" used by the Deflemask engine to play 7-bit PCM. rainwarrior released a special build of NSFPlay that will play such NSFs, or you can use foobar2000 (with foo_gep), NotSoFatso or Nestopia to play it as well. FCEUX will open and play the file, but you need to set the region bit to NTSC only.
Keen listeners will notice the obvious difference in pitch tables, but it shouldn't get in the way too much. :)
