You definitely made it sound like I've done nothing but slept while 
somebody else designed my products.  You're sadly mistaken, and just 
way off base.  Yet, if I defend it too much, it makes me sound like I 
have a reason to defend it.  So again.... the trap.  But I'm not 
crawfisin' away on this one.  I'm just tired of talking about it already.

There is no ~240 second megaread anymore.  This is at least the third 
time I've said this.  The OS-9 drivers do not read LSN0 on each 
sector transfer anymore.  That was a 2x slow-down right there.  I 
think I've said enough about the subject, as this is nothing more 
than an attempt to debunk an already popular device that I plan to 
support from here on out.

I don't need suggestions from Cloud-9, and I take care of my own 
customers.  On the other hand, I have nothing truly-truly personal 
against the people behind these words.  But I'm a very perceptive 
snapping turtle, so watch the fingers.  I can and will snap back hard.

 From here on out, for every suggestion Cloud-9 gives me about my 
stuff, I'll return the favor.

I'll start by asking you guys to not destroy any more game cartridges 
or historic paks to aquire your product cases.
