Wow, I can use a 2600 Trackball on this if I have a Redemption adapter? I have both, must give it a try, once I get one of my 5200s repaired (again.)
There's one thing that sticks out in this version which looks like it's incomplete - near the end of some levels, some insects will come out, particularly the one that walks along the bottom of the screen, and the next millipede doesn't appear until they're all gone. The arcade game and 2600 versions aren't like this.
Does the 8-bit version do this too? Hope I've expressed myself clearly enough
