I was thrilled to find Masterblazer a few years ago because there's no C64 or Atari800 emulator on the Amiga that emulates the original Ballblazer (or Ballblaster) correctly.
Masterblazer is great, but I wish they did a couple things differently. The screen size fits in NTSC, but they put it too high so the top bit gets cut on the NTSC 1084. They tried to give the goal posts and scoreboard a bit more detail, but it somehow ruins the original feel. Also, the high score screen has a horrible dithered grey background when they could have had a nice copper rainbow. I like the new "Hitchhiker's Guide to the Galaxy"-type history screens though.
The fractal mountain intro made me think they also did an Amiga Rescue on Fractalus, but sadly they didn't.
