Write errors with Disk ][ emulation

[petern]

MECC Number Munchers is unable to save high scores when running via CFFA3000 Disk ][ emulation. The game plays normally. When I achieve a high score, I enter my name and the game continues without error. However, the high scores never update. The disk image works as expected in the Virtual ][ emulator (i.e. high scores get saved). CFFA.LOG shows write errors.

Here's my configuration:

* CFFA3000 in slot 7 with Disk ][ emulation in slot 6
* firmware v3.0b2
* enhanced IIe
* disk image "MECC - Number Munchers (1986).dsk" from http://mirrors.apple2.org.za/ftp.apple. ... onal/mecc/
* generic 1 GB USB stick formatted FAT16+MBR
* OSX reports that the image is writeable

I've attached the debug log.

Thanks,

Thanks for the report! Bear with me while I juggle a big to-do list. From your CFFA.LOG I can see that it failed to interpret the nibbles for one sector, both of the times when it tried to write a track back to the image file. I've added some additional detail to the logging, for the next firmware version, and I will try to reproduce the problem here.

The problem persists with b8. Here's my debug log.

No apparent change with b14. Here's my debug log.

Thanks.
