I recently upgraded one of my trusty 1050's with an AtariMax repro Happy board. Mostly I want to play around with magnetic media again just kind of because, I figured it was a cheap and EASY upgrade for double-density, but it might be fun to screw around copying some of my old original disks from back in the Ferg ...
So tonight I pulled out my original SEVEN CITIES OF GOLD disk (which DOES boot, by the way) and tried to copy it with the Happy software that came with the board. I discovered the included "PDB" files, two of which are for different EA titles. #3 on the Happy disk specifically lists SEVEN CITIES as one of the titles, so I loaded it up, popped in my original disk and began. The software runs and tells me it has copied 11 tracks. When I swap disks to write a copy, it writes out the tracks, tells me to swap disks, etc. until finally it reports "Done."
So I power cycled my Atari and reboot - I get the EA logo, which shifts color for a moment as if the load is progressing normally, the drive head seeks back and forth several times and then stops, but the game never loads. I have tried booting the disk with various combinations of OS roms, expanded memory options and whatnot ... I even tried a brand new disk from a never-opened pack (until tonight). Nada.
The last thing I tried was to do a simple "Happy Backup Program", skipping the PDB file, and instead setting the special options to increase the number of sector reads, telling it to enable the skew setting, and set the drive to "Slow" mode (not "Unhappy Mode" per se). And now my copy works.
