Pax Imperia 1

Pax Imperia 1 cheat codes: 
Hex edit your saved game (make sure you've played the game
for at least a few minutes), and search for 0014 0000 0014
there will be about 5 of the 0014 (which is 20 in hex) in
close proximity to each other and these will be the amount of
percentage points alocated for each area of research from there
you can just change the numbers to whatever you want (00FF
would give you 255% in whatever field you want)  Although you
can do this for every field, just be careful that you don't
lower the percentage points for any field over while the game
is running as this will cause all research in that field to
stop since all the other R.Ps are in other fields.
