Firming up the Memory issue
"the lock bits, which let firmwares write-protect themselves, are only guaranteed for about a hundred toggles."
That means that if you are often "reformating" your NXT one day it may break.
I'd like to open comments for people to share if they have had alot of memory allocation problems.
I found that mine seem to happen most when you have big files as the first ones you've uploaded. So I might suggest that you load any mini programs first and save the beefy ones for later. However this means that you cant just load your biggest (best?) and see what else fits.
The Option in the memory manager to erase all user files might be the best bet, but if you have alot of mainstay programs you want always loaded it might be annoying.
Please comment on anything to do with memory here.
