Mario Party Cheat Codes & Secrets
Complete collection of cheat codes, passwords, unlockables, and hidden secrets for Mario Party (1998).
Secret Unlockables and the Eternal Star Board
Mario Party’s biggest hidden content centers on Toad’s Shop, accessible from the main menu. Every Star you earn during Party Mode and Mini-Game modes accumulates in your Star Bank. Spending these unlocks permanent content:
| Purchase Cost (Stars) | Unlocked Content |
|---|---|
| 100 Stars | Mini-Game Stadium (battle mode vs. CPU) |
| 150 Stars | Mini-Game Island (solo campaign) |
| 200 Stars | Mini-Game Comet (Bowser challenge run) |
| 980 Stars total spent | Eternal Star (hidden 7th board) |
Eternal Star is the game’s secret final board and the only way to face Bowser in a full party match. You must spend coins cumulatively across multiple visits — no single shortcut unlocks it. Play regular Party Mode sessions aggressively collecting coins from mini-games to build your Star Bank faster.
Mini-Game Island: Hidden Solo Campaign
Mini-Game Island is a rarely-discussed mode that functions as a linear gauntlet through all 50 mini-games. To access it you need to have purchased it from Toad’s Shop (150 Stars). Once active:
- You start with 4 lives and must clear every mini-game in sequence
- Winning a 4-player mini-game earns 1 life; 2-vs-2 mini-games earn 2 lives on a win
- Losing costs 1 life; reaching 0 lives sends you back to the start of the current mini-game cluster
- Clearing all 50 mini-games in one run unlocks a completion certificate and marks every mini-game as “mastered” in your records
This is the intended way to see the full mini-game roster without waiting for random board draws.
Mini-Game Comet: Bowser Challenge Mode
Purchased for 200 Stars from Toad’s Shop, Mini-Game Comet pits you against a CPU-controlled Bowser across a series of mini-game duels. Key details:
- Bowser plays on Hard difficulty regardless of your system settings
- Winning consecutive rounds without losing unlocks a bonus coin reward screen
- This mode is one of the few places you can rematch specific mini-games against a single hard opponent rather than three other players
Analog Stick Exploits and the Controller Warning
Several mini-games in Mario Party 1 require rapidly rotating the N64 analog stick, and this mechanic has specific exploits:
| Mini-Game | Exploit | Technique |
|---|---|---|
| Piranha’s Pursuit | Max sprint speed | Palm-roll the stick in fast clockwise circles rather than rotating with fingertips |
| Running of the Bulge | Sustain lead indefinitely | Same palm-roll technique; maintain rhythm rather than bursting |
| Tug o’ War | Counter CPU timing | Rotate at steady medium pace — the CPU’s win threshold is timed, not force-based |
| Paddle Battle | Distance boost | Consistent circular motion beats erratic rapid tapping |
Nintendo acknowledged that palm-rolling the stick caused friction burns and blisters, leading to a 2000 settlement where they mailed protective gloves to players who contacted Nintendo of America. On emulator, analog stick rotation mini-games are mapped to rapid button presses (typically bound to a face button for stick-spin), completely bypassing the physical strain.
Bumper Balls Positioning Exploit
In the Bumper Balls mini-game (4-player free-for-all on a shrinking platform), the center of the arena has a slight physics advantage:
- CPU opponents almost always charge toward the nearest player
- Standing at the exact center causes incoming CPUs to collide with each other before reaching you
- Human players can exploit this by drifting back toward center after each deflection rather than chasing opponents to the edge
Chance Time Manipulation
Chance Time is the board event that can swap Stars or coins between players. The roulette wheel uses a frame-based seed, not a true random roll:
- The wheel completes a full predictable cycle roughly every 3 seconds of idle time on the Chance Time screen
- Pressing A to spin at the moment the visual pointer passes the top of the wheel tends to land on the first third of the outcome list
- On PAL versions this timing shifts slightly due to the 50Hz framerate — aim for the pointer passing roughly one-eighth past top
This is not 100% consistent but experienced players report noticeably skewing outcomes by timing the A press during real hardware play.
Bonus Star Farming Strategies
At the end of every Party Mode game, three Bonus Stars are awarded:
| Bonus Star | Condition | How to Target It |
|---|---|---|
| Happening Star | Most Happening spaces hit | Prioritize red event spaces even when Blue spaces are closer |
| Coin Star | Most coins at game end | Hoard coins late game rather than spending on items |
| Mini-Game Star | Most mini-game wins | On boards with predictable mini-game tiles, route to those spaces |
The Coin Star and Mini-Game Star are stackable strategies — strong mini-game players can feasibly earn both in the same game. Because Bonus Stars are worth exactly 1 Star each (same as a purchased Star on the board), winning two bonuses while collecting 4 board Stars beats a player who collected 5 board Stars and no bonuses.
Hard Mode CPU Behavior Notes
The game has no explicit difficulty code toggle but Hard CPU opponents behave differently in specific mini-games:
- In Mushroom Mix-Up, Hard CPUs track color changes approximately 2 seconds faster than Medium
- In Slot Car Derby, Hard CPUs accelerate on the straightaways and brake earlier into curves — matching their brake point (roughly 3 car-lengths before the curve marker) is more effective than trying to outrun them on straights
- In Board Game Island (special mini-game), Hard CPUs will sacrifice a coin spend to block your path rather than taking the optimal route to their own goal
Toad’s Shop Star-Earning Efficiency
Since unlocking Eternal Star requires 980 cumulative Stars spent, here is the fastest grinding path:
- Run 4-player Party Mode games on Yoshi’s Tropical Island (shortest board, 20 turns minimum)
- Set three CPUs to Hard difficulty — Hard CPUs complete mini-games faster, reducing wait time per round
- Focus on 4-player mini-games over 1-vs-3 types: 4-player wins award Stars to the full board rather than splitting outcomes
- A 20-turn game on Yoshi’s yields roughly 8–12 Stars per session including Bonus Stars
- At that rate, Eternal Star requires approximately 80–120 sessions — playing in bursts of 3–4 games significantly accelerates the unlock
Easter Egg: Bowser’s Laugh on Title Screen
On the title screen, wait without pressing any button for approximately 45 seconds. Bowser’s laugh sound effect triggers and the background briefly shifts to a dark red hue before cycling back. This idle animation was cut from the North American release intro but the audio cue remains in the ROM and fires on the title screen idle loop in all regional versions.
