Coins

Coins puts coins on every race course: the game's own and every course mod's. Turn them on in the - menu under GAME > COINS. They're used in Grand Prix and Versus, not in Time Trial (so records and ghosts stay fair), battles or LAN play. A change takes effect at the next race.

How they work

  • Every kart picks them up, yours and the CPUs'. A kart holds up to 10, and each one raises its top speed by 1%.
  • Being hit (a spin, a big hit or a burn) or falling off the course (when Lakitu picks you up) loses 3 coins.
  • A coin comes back 10 seconds after it was taken.
  • Coins over water (Peach Beach) float on it and move with the tide.
  • RETRY on the pause screen starts every kart again with none, and puts all the coins back.
  • The HUD shows how many you hold, on each player's screen in split screen, until that player finishes. HUD ASSETS > COINS in the - menu hides the counter.

You don't have to place anything. MKDD-NX lays out rows of coins along each course from the course's own data, so a course mod gets coins too. The layout is the same every race, on every console.

Placing your own

The Coins tab in the MKDD-NX Tools app (download it as described on Battle Routes) edits the coins of any race course.

At the top of the tab, pick three things with their Browse… buttons. The tab remembers them for next time:

  1. Coins folder: where layouts are saved. On the Switch, pick switch/MKDD-NX/mods/coins on the SD card (create the coins folder in mods if there is none). On Windows, mods/coins next to MKDD-NX.exe. Layouts in the older coins folder still work.
  2. Disc image: your own .iso, .gcm, .ciso or .rvz, to draw the courses. It's only read; nothing from it is saved.
  3. Mod folder (optional): a course mod's folder (the one holding files), to edit its courses. None clears it.

Pick a course at the top left. It's drawn from above: the road grey, off-road green, water blue, the CPUs' line dotted, item boxes as blue squares and the start as a green circle. A course with no file of yours shows the layout the game makes.

Do How
Add coins Left click. Row sets how many in a row, lined up with the course there. Shift + click puts them on the lowest floor (under a bridge).
Move a coin Left drag it
Remove a coin Right click it
Move the view Right or middle drag
Zoom Mouse wheel
Undo Ctrl+Z

The buttons:

  • Generate: the layout the game makes, to start from.
  • Clear: no coins.
  • Save: the next race on that course uses your layout. Saving a course with no coins turns coins off there.
  • Reload: back to the saved file.
  • Remove file: back to the layout the game makes. The file is kept as .bak.

Each layout is a text file named after the course and its data (22_3a7367a8.txt is Peach Beach), so a mod's version of a course gets its own file. It holds one coin per line, x y z. Up to 384 coins per course.
