(love my Finnish keyboard, it won't accept any \s there, just /, but they both work whatsoever.)

Z:\>c:/cd lion/LION
Unable to change to lion/LION

Nope.

Try:

mount c: c:/users/ttx/oldgames
c:
cd lion
lion


..... And of course hit enter after every line.

[Edit]
BTW, you apparently didn't followed the how to, or you would have a C in dosbox in stead of a Z .....
