Richard, did you miss new scsi_atapi_fixup_inquiry() in blkdev.c?
It fixes this problem. PlayCD wants ANSI version == 2 or complains
and exits. (ATAPI ~ SCSI-2 minus MODE_SENSE_6, MODE_SELECT_6 and ANSI
version == 0 in INQUIRY)
The problem on OS X, though, is that this translation code won't be used,
because libscg (the SCSI transport library) doesn't report when a device is
actually an ATAPI device on OS X.
Neither does Windows.. (SPTI or ASPI)
I use this piece of code to detect ATAPI:
static int isatapi (int unitnum)
{
uae_u8 cmd[6] = { 0x12,0,0,0,36,0 }; /* INQUIRY */
uae_u8 out[36];
int outlen = sizeof (out);
uae_u8 *p = execscsicmd_in (unitnum, cmd, sizeof (cmd), &outlen);
if (!p)
return 0;
if (outlen >= 2 && (p[0] & 31) == 5 && (p[2] & 7) == 0)
return 1;
return 0;
}
