I change below in constants.ini
[EngineEquipConsts]

CRUISING_SPEED = 400 (I changed it to 800)

[PhySysConsts]
ANOM_LIMITS_MAX_VELOCITY = 400 ( I changed it to 1000)

And I also change engine_Equip.ini to make the cruising speed to be 800; also cange the setting of thrusters,
Theoretically I did every thing I could but it just don’t work, the coasting speed of ships is still can not exceed 400.
The speed of missiles & torps can not exceed 400, even I launch them from a coasting ship……
I was confused, I must have miss something.
I also check the topic of offset edit of freelancer.exe but found no topic about it, just some topic of change cruising speed display .
I also checked 0x1D7E80 in freelancer.exe, I saw that is 300f (but I got 400 cruising speed)

I think its a good idea.
