NTVDM CPU Has ecountered illegal instn

[John M Carter]

My wife wants to run an old DOS game on her new computer so I tranferred it
across and tried to run it but up comes the above message followed by
CS:0000 IP:0075 OP:f0 00 fO 37 05.
Now I think it's got something to do with 16 bit games not working on 32 bit
os but can anyone confirm and is ther a way to run this old game? OS is Win
XP Home
Many thanks

Select the game, Right Click and select / Properties.
One Window enables several "Compatibility" settings.
One of these may help your game run OK (but be
warned that DOS games that use 1995 CPU speeds to
regulate any games function may trip themselves
up on faster CPUs today.)
