This video shows my first attempt at stage 9-4 and then a successful run of stage 9-4.

9-1 Bring the Shotgun Ice.
Fire in the perfect rhythm to deal quick damage to Mandrill. Hovering is the key to this. Don't stay on the walls.
When Turtloid does the "Owari da!" attack, get to the wall and hover while facing it. Fire Shotgun Ice shots so their spread takes out Turtloid's projectiles.
When Turtloid does his final attack, again, hover next to the wall facing away from it, fire charged shots to hit the falling Meteor Rain, then slide down the wall using the saber to hit any remaining Meteor Rain shots coming your way.

9-2 Buster these guys. You need to keep your Chameleon Sting and Meteor Rain ammo for 9-3.
Focus on Metal Shark Player with mid-level charged shots while watching out for Eagle. As usual stay on the ground and react to Shark's attacks with tall dash jumps out of his way. The only thing that can mess this up is if spams Metal Anchors too much. Or if Eagle is in your way of dodging Shark's summon attacks.

9-3 An RNG nightmare. Equip the Meteor Rain, but charge the buster for the first attack.
Hit Dynamo with Meteor Rain shots. 2 Meteor Rain shots if you can go on the wall behind him. 1 shot to his face if you can't go to the wall. If you fire your shots in his face, it will hit him twice. Hitting Dynamo a second time after stunning him will automatically make him jump to the other side of the room.
During your quest to kill Dynamo, try to do some maintenance on the orbs Gate throws at you whenever you can to deal some damage to Gate and make the fight manageable.
Red orbs are a priority. You have to take them out otherwise they will eat your inputs and most likely get you killed.
The orbs take 5 shots. 1 fully charged shot + 1 mid-charged shot.
When Dynamo is at half health and you see him go to the center of the screen, if you are safe from harm, switch to Chameleon Sting and charge it. Use the pause menu if necessary to avoid wasting ammo when you start charging the weapon.
Trigger your invincibility when Dynamo starts his attack from the center of the screen, then spam sets of 2 shots on him to deal heavy damage. Destroy Gate's orbs as they get to you.
Your invincibility should wear off as Dynamo jumps away from the center of the room. So you'll be able to repeat the same pattern 3 other times.
When only Gate is left, lure him around the room. Make sure that Dynamo's ghost jumps to the proper corner for his attack. He always jumps on the side of the screen you are not in.
Dynamo's ghost has no hit box so don't worry about running into him
Gate is so RNG heavy. No matter how much you practice, Gate can completely screw things up.

9-4 All your special weapons energy, life energy and extra-lives are restored for this secret battle. Beating them or losing all your lives will take you to the credits. You can't practice this fight.
Use the invincibility to deal some damage and wait for Zero to dash to the lower right corner. When he does, climb to the top of the wall.
Keep jumping from the wall. Jump away and hover to dodge the rising energy shots. Your cue to drop further down to lure the first energy ring is when the saber wave is exiting the screen.
Fire Shotgun Ice shots when Zero fires his first energy ring and between the 2nd and 3rd rising ground shots. If you fire ice too often, their spread will ding off Zero's saber wave.
When out of Shotgun Ice, charge the invincibility and drop down to hit both X and Zero. Drop after Zero used the saber wave. Go back up the wall after Zero's next 2 energy rings started to move away. Repeat. Remember to use the pause menu to avoid wasting ammo.
With Zero dead, stay at the top again and wait for X to bounce off the wall to drop down and fire at him.
Watch out for a charged Ray Arrow attack when X glows purple.
Good luck.

Hard Mode bosses deal more damage (especially collision damage) and they take less damage as well. You have to practice and learn how the bosses work. A lot.
The final secret battle is only accessible when beating Stage 9 on Hard.
