As far as i can tell, these would also be nice options to have(but not necessary):
Infinite MRP, no collision damage (difficulty and certain aircraft parts can affect this so there is a value for it), no missile/bomb reload time, infinite tuning parts capacity(both overall 8 part limit and body/arms/misc limit, may not be possible due to potential UI issues as a result + other difficulties)
EDIT: There seems to be a soft anti-cheat or memory integrity check in the game. I tried to change the MRP myself. it seemingly changes over fine but crashes when you try to buy anything
