Why this one is in the canon, and how to start it well.
I remember beating this guy in Punch-Out on the NES.

The code culture around Punch-Out!! was immediate and layered. The game shipped with a password system that let players skip circuits, and the famous 007-373-5963 code—which jumped straight to the Tyson dream fight—became one of the most widely circulated secrets of the 8-bit era, passed via Nintendo Power tip lines, schoolyard whispers, and early BBS posts. When Galoob’s Game Genie launched in 1990, Punch-Out!! was a flagship title: infinite hearts, one-punch knockdowns, opponent-stun codes that froze AI patterns mid-match. The same year, Nintendo’s Tyson license expired and the game was re-released as simply Punch-Out!! with the fictional Mr. Dream replacing Tyson as the final boss—a move that made the original Tyson cartridge a collector artifact while keeping the core game in print for Virtual Console, NES Classic, and Switch Online releases. The two versions are mechanically identical; the same passwords and Game Genie codes work on both, cementing Punch-Out!! as a game where mastery, secrets, and cheat-device experimentation were inseparable from the experience.
Master the two-button defense immediately. Left dodges left, right dodges right, down ducks. B blocks but drains stamina—use it sparingly. Every opponent telegraphs punches with a visual cue (eye twitch, mouth movement, glove drop). Spend your first fight against Glass Joe learning to react to these tells instead of mashing buttons.
Earn stars, spend stars. Land a jab (A button) during an opponent’s tell window to collect a star (max three). Press Start to throw a devastating uppercut that costs one star. Stars reset between rounds and disappear if you get hit—use them before the round ends or an opponent connects.
Watch the stamina meter constantly. The hearts at the top-right deplete when you throw blocked punches or take body blows. At zero hearts, Mac turns pink and can only block—no punches. Dodge attacks to recover stamina; blocking doesn’t help. If you go pink mid-round, play pure defense until hearts return.
Learn the between-rounds window. Press Select during the 60-second rest to call Doc Louis for a one-word hint about your current opponent’s weakness. It’s cryptic but always accurate. This is your only in-game tutorial.
Memorize the Major Circuit password system. After each win, the game displays a ten-character code (example: 005 737 5423). Write it down. There are no saves—passwords are your only way to skip rematches. The World Circuit password (007 373 5963) puts you one fight from Tyson/Dream.
Abuse the frame-perfect instant knockdown. Many opponents have a single-frame vulnerability where a specific punch (usually a jab to the face or gut) triggers an immediate knockdown regardless of their health. Glass Joe’s jaw-drop taunt, Piston Honda’s eyebrow twitch before the rush, Bald Bull’s charging hop—these windows exist for nearly every boxer. TASVideos documents the exact frames; practice the timing in exhibition mode.
Understand the three-knockdown rule and the stamina-drain loss. Three knockdowns in one round = TKO loss for that boxer. If the round timer expires, the boxer with more stamina (hearts) wins by decision. You cannot win by decision in Title Defense rematches—you must KO or TKO.
Stars are currency, not decoration. Land a punch the instant an opponent telegraphs an attack (usually right before their eyes flash) to earn a star. Star uppercuts deal massive damage and interrupt nearly every animation — hoard them for desperation moments or use one to break an opponent’s rhythm when you’re struggling to find openings.
The tell always comes before the animation. Every boxer has a visual or audio cue 10–30 frames before their punch actually launches. Glass Joe blinks, Von Kaiser ducks slightly, Piston Honda’s eyebrows twitch, Bald Bull snorts. Learn these micro-tells and you dodge before the windup finishes — reactive dodging is too slow past the Minor Circuit.
Body blows open guards; jabs fish for stars. Opponents block high after taking head damage. Two or three body hooks force them to drop their guard, then snap off face jabs for star opportunities. Alternating high-low is faster than waiting for scripted openings against defensive boxers like Don Flamenco or Super Macho Man.
Stamina dictates damage, not just speed. When Mac is pink and flashing after taking hits, your punches deal half damage and you can’t earn stars. Dodge or block until the pink fades — mashing attacks while hurt extends fights and burns the round timer.
Round 1 is for learning, Round 2 is for winning. Most opponents introduce new patterns or tighten their timing in later rounds. Use Round 1 to catalog every tell and test counter-windows without worrying about the KO. The TD/KO bonus is negligible compared to learning the fight properly.
The walls players actually hit, and the way through each.
Glass Joe’s star-punch timing (Minor Circuit)
First-time players burn through all their hearts throwing body blows at Glass Joe, missing the core mechanic entirely. Wait for his taunt — the wind-up where he blinks — dodge left or right, then counter-punch his face the instant the dodge completes. One clean dodge-counter earns a star; press Start to throw the star punch for massive damage. This pattern repeats against every opponent in the game. Learn it here or suffer through Major Circuit.
King Hippo’s band-aid vulnerability (Major Circuit)
Hippo’s defense looks impenetrable until you notice the X-marked band-aid on his trunks. Wait for his mouth to open during the wind-up, punch his face to stun him, then hammer body blows immediately while his trunks drop. Once the band-aid is exposed, only body shots register damage. Miss this window and he recovers full defense. Players who spam head punches never advance — this fight teaches target-switching discipline required for Soda Popinski and Super Macho Man later.
Bald Bull’s charge counter (Major Circuit / Title Defense)
The bull charge one-shots Mac if it connects. Most players panic-dodge and lose position. The solution: wait until Bull is mid-screen — roughly three steps into the charge — then throw a body blow or star punch directly into his approach. Timing is character-animation based, not audio cue. Watch his head-bob rhythm. Practice mode doesn’t exist, so expect to lose rounds learning the window. This same counter-charge technique works against his Title Defense rematch and Mr. Sandman’s rushing attacks.
Super Macho Man’s spin-punch cycle (World Circuit)
Macho Man’s super spin punch deals catastrophic damage and he throws it constantly in Round 2+. The telegraph: three rapid pec-flexes followed by the spin. Dodge left on the third flex, counter-punch immediately. Players who wait for the spin itself to start are already hit. The flex-count resets if you interrupt with a body blow, but mistiming gives him a free opening. World Circuit opponents punish hesitation — commit to the three-flex read or accept the knockdown.
