Unable to select No-flip

Jim,

I'm having an odd issue using a flippy-modded drive reading C64 disks. I have one of sncboom2k's Panasonic flippy modded drives, which I have used with a Kryoflux. I'm trying to use this drive with the SCP, but I'm unable to select No-flip (-4 tracks) from the Backside Control menu, which I understand is the setting for the Panasonic drive. When I select the -4 option, the software selects the +4 option. Attempted reads of the disk fail with the red blocks on the grid. If I turn off backside control, it will read the "front" side of the disk just fine.

Although I can choose both -4 tracks or +4 tracks from the menu, the program always selects +4 tracks in either case.

Any idea what could be going on?

Thank you,

Jose

What is the "No-Flip" mod?

The No-Flip Mod allows you to read the backside of disk without having to remove it from the drive, flip it over, and re-insert it into the drive. Hence the name No-Flip. Others refer to this as "the flippy mod" which makes no sense. "Flippy disks" were those that were double-sided, typically having two different computer formats - one on each side of the disk.
