Hi. A comment in this bug report about os9 attr and copy always returning success seems to say that the issue could be fixed "after 2.3 has been released". Has a date been considered for releasing 2.3? (Version 2.2 is the latest on this page.) After that, I'd be interested in the fix. Thanks for writing ToolShed.
Intriguing... Is there a story behind this? Should this bug be reported to mame-dev? I confirm that removing the first 2 bytes fixes the issue. I used this command under Linux: dd if=example.dsk of=fixed.dsk ibs=1 skip=2 Thanks for your help.
After the build command, I ran md5sum under Linux on the floppy image before and after closing MAME, and got the same signature. To be noted: the modified floppy image is 2 bytes longer than it was right after "os9 format" created it. Now that you've reproduced the problem, I assume you won't need my disk images.
os9 dir gives error 216 after floppy image written to by NitrOS-9 in MAME
