Gemini Bit Copier (1985)

Claims a nice 99.9% Effective! 3 Minutes Copy, Copies Bit by Bit.
Programmed in 100% machine language, writes errors, more.
Sounds great, but I never used this program and can not find a copy.

The credits show three people including Jim Drew!
The other two are Steve Bern and Darryl Millard.
My copy of the program freezes at the image below!

    • Hmmm, I only have a G64 of V2. I haven’t tried to write the G64 back to disk and then run. Would that work? Or does it has some type of crack tough protection Jim?

  1. If I remember correctly, this program used a high track for its copy protection. How I remember the procedure I used to first copy it was as follows: I sent the R/W head to track 40 on my 1541, then pulled the stepper motor wire and proceeded to do a normal disk format for a bit which seemed to do the trick (drive ended up formatting track 40 over and over). This was before I knew much about the 1541 and not much later on I could have done it in software (I was only 14 or 15 at the time). I am guessing it used a different disk ID on track 40 or possibly just the presence of a formatted track as its protection but I can’t remember exactly.
