Rockman 4 Minus Infinity is a Rockman 4ROM hack by a Japanese person who goes by PureSabe.While otherROM hacks tend to just make the original game harder or alter it in a few ways and little else, this one ascends beyond this status to turn the original game into an incredible experience. The staggering amount of new content include new level designs, bosses, features, weapons, music, enemies from other Mega Man titles, Shout Outs to other video games, and more!This site contains lots of information on the game.Robot Masters
DCN-025: Bright Man, weak to Homing Control Ring Boomerang, gives Spark Manbow
DCN-026: Toad Man, weak to Pharaoh Shotgun and Toad Spell, gives Toad Spell
DCN-027: Drill Man, weak to Water Cutter and Hell Wheel, gives DrillTorpedo
DCN-028: Pharaoh Man, weak to Drill Torpedo and Hell Wheel, gives PharaohShotgun
As are the Bait-and-Switch Boss and the True Final Boss. Mega Man figures out that they're holograms almost immediately, but that doesn't make them any less dangerous.
Adaptation Expansion: Adds numerous new bosses/mini-bosses, enemies and even more gameplay changes.
Artificial Brilliance: If you use Rush during the Snatchman battle, the doppelganger will use it against you. Yes, you can end up healing the boss when you're low on health! To really rub it in, it still uses your weapon energy.
A.I. Breaker: Using Recycle Inhaler to trap Snatchman in an E-Tank, however, gives Rush back to you. You can use this to One-Hit Kill the boss with Rush Cannon.
Puresabe seems to be a big fan of Rockman World 5 and Mega Man X2. The Cossack bosses are based on the X-Hunters and the Charge Shot looks like the Charge Shot from X2. Some of the enemies and gimmicks from Rockman World 5 show up.
He also seems to like Shadow Man a lot, as the latter is fought several times throughout the game.
Baleful Polymorph: Toad Man's Toad Spell, when used by him, turns you into a defenseless frog from Kaeru no Tame ni Kane wa Naru. When used by you, it turns enemies (and items) into tiny, harmless toads.
Berserk Button: Pharaoh Man gets upset when Mega Man destroys the statues in his stage and later challenges him to a battle when Mega Man destroys the coffin in his room.
Blackout Basement: The first half of Bright Man's level. You can see the level in general, but not enemies and objects under or over you.
"Blind Idiot" Translation: Although Puresabe did admit his bad English skills in the English readme file.
Bonus Boss: Wave Man in Dive Man's Stage and Crash Man in Drill Man's stage. Beat them and unlock the Wire and Balloon Adaptors before the Cossack stages.
Bottomless Pit Rescue Service: If you find and rescue Beat in Skull Man's stage and Cossack Castle Stage 1, he does this for you at the cost of some of your HP for the rest of the stage.
Boss in Mook Clothing: The Jumbig, which takes 127 Mega Buster shots to kill. Oh, and did we mention that he appears at least once in every level?
And he pushes you back if you run into him, so you can't just abuse invincibility frames to bypass him. And on top of that, he gains some additional attacks in the fortress levels...
Credits Medley: Played With - the credits theme is a medley of three credits themes from the Kirby series, specifically Super Star, Block Ball, and Dream Course.
Critical Hit: Happens on occasion. Get the Super Star from any Shadow Man encounter by finishing him off with a Recycle Inhaler, and the chances of this increases.
Damsel in Distress: Mega Man has to break Kalinka out of a cage (guarded by a Copy Roll, of all things), in order to advance in Wily Castle stage 3.
Dead Character Walking: A variation - if you die while using Hell Wheel, the wheel keeps going (along with the camera). In some points you can even get to the next screen this way (though you obviously can't do anything)!
Eleventh Hour Superpower: However, if you find yourself losing said final battle, Proto Man comes in to give you the Wily Buster and refill all your health. The Wily Buster shoots charged shots instantly and reduces all damage taken from the Petit Robot Masters.
End Game Results Screen: The game calculates your "hero score" based on a number of factors (i.e. if you rescued Rush and Beat or sucked up Eddie with the Recycle Inhaler, or getting all the secret items), with Proto Man giving a comment based on what you did wrong (if you did anything wrong).
Evil Knockoff: Snatchman in Wily Stage 2. If you beat him once, he steals 4 of your Robot Master Weapons with the help of Dr. Wily's Stealing System.
Feed It With Fire: Dust Man, with anything except Toad Spell when he is using Recycle Inhaler.
Dangerously Genre Savvy: Wily triggers the usual Self-Destruct Mechanism at the end, but he also has an anti-teleportation field preventing Mega Man from just beaming out. Instead, he has to escape the Collapsing Lair on foot (or rather on the Hell Wheel).
Bright Man has two: the first half of the stage is only lit on your X-axis position, while the second half uses red, blue and green disappearing blocks, which damage you should you be in them when they appear. There are also ladders and Spikes of Doom that function in this manner.
Pharaoh Man's stage contains the curses that do various things to you depending on where you're at in the pyramid. Oh, and the boss fights against him involve these curses too.
Toad Spell turns the debris Dust Man expels out of his Arm Cannon into toads. When he inhales it back in, he gets damaged instead.
Toad Man, in a homage to Mega Man 2, gets killed in one hit if you use Toad Spell on him. Probably because the Toad Spell cures the Toad status in the Final Fantasy games.
Hologram: Crash Man and Wave Man. The alien lair, as well as the Petit Robot Masters.
Horse of a Different Color: In a homage to the Mega Man Power Battle/Fighters series, Shadow Man rides on a giant toad in Toad Man's stage.
HP To One: Shock Guard Upgrade turns the spikes into these.
I Fell for Hours: After beating Bullet Hell Mothraya and Serges Devil Machine.
Shadow Man in Toad Man, Bright Man, and Pharaoh Man's stages, as well as Cossack Castle Stage 1.
Whopper and Rong Rong Rong, Rang Rang Rang, and Rung Rung Rung in Ring Man's stage, which is a homage to Lololo and Lalala from the Kirby game series.
Hogale and Enker in Dive Man's stage.
Quint and Kabatoncue in Drill Man's stage.
King Gajuras in Skull Man's stage.
Giant/Nightmare Suzy, Terra, Ballade, and Punk in Cossack Castle 4. They guard the generators powering the barrier leading to Dr. Cossack.
Gamarn and Gamadayu in Toad Man's stage.
Multiple Endings: The ending of the game has several permutations depending on your actions:
If you rescue Rush during the final level, Mega Man will use Rush Cannon on Wily's space ship upon escaping the castle. Otherwise, Mega Man will collide with the space ship instead, destroying it regardless.
Eddie, Rush, and Beat make appearances depending on if you used the Recycle Inhaler on the former and/or rescued the other two during the final level.
If you turned Toad Man into a toad during the rematch and spared him, he will appear in the first part of the credits, hopping alongside the train.
Depending on what happened to Rush, Eddie, and Beat at the end of the game, they will appear either in color or grey in the "Presented by Capcom" screen.
The Wily Machine's first phase has one full health bar, where each hit point represents its own separate health bar. That adds up to 29 times 28, or 812 hit points.
The Wily Capsule later on has two health bars, giving it 56 hit points.
And then the Petit Robot Masters, who each has his own lifebar, with the one last hit's currently shown. That adds up to 8 times 28, or 224 hit points.
Mythology Gag: There are a whole lot of enemies from other Mega Man games, for starters.
The lifebars/HUD from the Game Boy Mega Man games (also known as the Rockman World series) show up for the first half of Bright Man's stage. They also appear when fighting the Wily Capsule and the Petit Robot Masters.
Holdable Control Ring Boomerang gains the Power-Up Magnet abilities of its Game Boy version.
Drill Man's stage contains Ring Man's hippo Mini-Boss, which has the blocks of its Game Boy counterpart.
Pluto's Mini-Boss also appears, and Drill Man himself copies Uranus' Desperation Attack of crashing the ceiling down on you.
Pharaoh Man and Drill Man's stages also contain falling blocks from the fourth Game Boy game.
AndLiving Statues of Fire Man, Heat Man, and Flame Man show up at the very end of the former.
An enemy from Aqua Man's stage in Mega Man 8 appears in Dive Man's stage here.
The Balloon Adapter is based on the Rush Jet Adapter from Mega Man 3.
The manner in which the Chimerabots are set up is similar to that of the Doc Robots from Mega Man 3, complete with the beginning of Mega Man 3's boss theme playing.
The tokens dropped by the Robot Masters in Wily Stage 3 are taken from Mega Man 1. They are replaced by Yashichis whenever their rooms are revisited.
When Crash Man and Wave Man's holograms are defeated, the device used to operate them appears. It's the exact same projector Dr. Wily used for his alien form in Mega Man 2's final battle.
Suspicious Video Game Generosity: Extra life and E-Tank drops are extremely common in this game. The final levels of the game give you lots of health and ammo. It's even the page image!
Timed Mission: The escape sequence gives the player one minute to escape the self destructing Wily Castle.
Time Stands Still: If you hold up when you use the Spark. Manbow, all the enemies on the screen except a few get frozen for a few seconds.
Turns Red: All of the Cossack Robot Masters have a more aggressive "Pinch" mode that activates when they reach critical health, complete with pallete change and faster music, with Pharaoh Man notably taking this to extremelengths. When you refight them in Wily Stage 3, they are already in their Pinch mode behaviour, but retain their original palletes and music.
Unexpected Shmup Level: Cossack Stage 1's second half, which has you ride on the Balloon Adaptor until Shadow Man ambushes you. After the Mini-Boss battle, you do some Sky Surfing with Rush.
In the rematch against Toad Man, you can turn him into a toad then spare him by not squishing him. He (as a toad) appears in the credits if you do this, and you get points added to your score.
Use Recycle Inhaler on Eddie and he turns into a Energy Splitter. However, do that and Eddie won't give you any warnings for Cossack Stage 1 and Wily Stage 2 or show up to give you any powerups in the other stages. Proto Man will even lament his loss in the post-credits results screen.
Proto Man: Your rookie ... Eddy. It's regrettable about him. I've never expected that his core have not found in the ruin of Wily's fortless. ...! Are you trembling? I see... as I heard that his signal disappeared near you, you saw his last moment... didn't you? Don't mind, you had done best effort to him.
A lesser example can be done, in Dive Man's stage; the Up'N'Down enemy wears a scuba diving mask for its appearance there, but if you shoot it off, it will drown and explode.
