Need for Speed Underground 2 v1.01 [trainer +3]
01. F8 - Takes your current earnings and adds $10000 to the
02. F9 - Locks your money so that it does not decrease when
purchasing from any of the 5 shops.
03. F10 - Enters automatically refilling NOS mode. When you
release your NOS key then your guage will be refilled.
04. F11 - Clears the effect of the previous two cheats. F9 and 10
are not toggles, so if you wish to disable either of
them then you need to use this key.
At first glance you might come to the conclusion that function F8
voids the requirement for F9. Clearly you do not need to use both,
they are both provided so that you can choose to what degree you
cheat by. F8 is irreversible effect. F9 is not.
We tried to do unlimited NOS rather than refilling NOS. The
difference is that you could keep the key depressed forever and
continue to NOS for the entire race if you wished, but this
caused undesired behavour, for example, AI cars were no longer
racing around the track amonst other undesired behaviours. We
believe this has something to do with protection that is built
into the game to prevent cheating.
