i know. i thought about this problem after i released it. i've been too
lazy to work much more on the site so i didn't change the routine. i've
never had it screw up when i tested it, but i have probably just been
lucky (it would be nice if the ti86 only started variable data storage on
certain LSB addresses).
thanks for pointing this out though. this is a section that i intend to
work on heavily in the future because i wish there were some more shells
out there.
also, brent, remember that we were talking about 82/85 emulation? i
figured out how to do it and now it's just a matter of time and reworking
all those ROM calls for the different addresses. i'm going to make a
section on that too once i get a working sample ready. it stinks that we
can never fully emulate them though.
by the way, how are you coming on that shell? if you were going to do
plug-ins, have you figured out a way to work them in? good luck on the
project!
