<p> What has changed in Mini vMac 37.00, compared to Mini vMac 36.04.
This only lists changes that affect behavior, and so doesn't

Mini vMac will now check if a disk image that is being
mounted looks like a Macintosh disk image format (HFS or MFS), and
if not decline to mount it, showing an error message. This helps
prevent accidentally corrupting other files, especially when using
ImportFl.
</p>
<p>
But there are some other disk image formats that you might want to
mount, such as Fat16 and ISO (which can be used by the emulated
Macintosh with additional software). Or, you may be trying to create
your own new disk image and want the emulated Macintosh to initialize it.
In these cases you can use a version of Mini vMac compiled with the new
“<a href="../options.html#option_ndp">-ndp 0</a>”
option to turn off this protection.
</p>
<p>
If a Branch option prior to 37
is chosen for compatibility with an earlier version,
the default is “-npd 0”, and you can
use “-npd 1” to turn on this protection.

The new
“<a href="../options.html#option_lto">-lto</a>”
option provides alternative transport for LocalTalk emulation.
In addition to Mike Fort’s original code for LocalTalk
over BPF (Berkeley Packet Filter), there is new code from
Rob Mitchelmore for LocalTalk over UPD (User Datagram Protocol),
that does not require setup or administrative privileges.
The new UPD option is now the default for branch 37. If a prior
“-br” (Branch) option is chosen for compatibility with an
earlier version, the default is BPF.

The built in disassembler
(enabled with “<a href="../develop.html#option_d">-dis 1</a>”)
incorrectly handled the BCHG/BCLR/BSET/BTST instructions.
Thanks to Ryan for
