Few tips for any future runners:

• the King IO chopper can be unlocked after beating mission 7 (or going into debug mode and setting mission 7 to being beaten) and then holding Z + R + L when pressing New Game. You have to hold the buttons until the next screen appears. Debug mode can be entered by holding down the Z button and press D-pad Right, D-Pad Left, D-Pad Up, D-Pad Down, A, B and Start on the title screen.
• we wait at the start of the game for the demo to start playing and if you press start at the start of the demo you will get a favorable RNG seed or pattern for the first two missions in the game.
• backround music should be turned of because it reduces lag (saves 40-50 seconds). The SFX audio can also be turned of to reduce lag even further but I personally did not want to speedrun the game like that, since it kind of ruins the experience.
• in mission 3 you have to destroy all the extra choppers because by destroying them the target count in mission 4 goes down. You can track this by looking at the Enemy Destruction Percentage after completing the mission and ideally that should be between 90 and 100%
• In mission 4 be careful not to shoot the building with POVs in them since that will spawn the rescue chopper and some of the enemy choppers might start going after the rescue chopper instead of following you
• in mission 5 be careful to shoot all the individual modules on the enemy targets. (The two buildings you have to shoot have 4 modules each)
• In mission 6 you can also shoot a few extra enemies to reduce the target count in mission 7 (from 51 to maybe 46 or 47). 7thArmstrong developed this so contact him for more knowledge on this.
• lastly the enemy planes take more damage it you shoot them in the center, as opposed to their wings.
