You cannot change handedness via a menu setting. Wii Sports Resort basketball reads **which hand holds the Wii Remote** to determine shooting hand.
| Sport | Left-Handed Friendly? | Why |
|---|---|---|
| **Swordplay** | ✅ Excellent | 1:1 motion — swing naturally with dominant hand |
| **Table Tennis** | ✅ Excellent | Remote = paddle; no Nunchuk needed |
| **Archery** | ✅ Excellent | Hold Remote like bow, Nunchuk like string — works either hand |
| **Frisbee Dog** | ✅ Good | Flick Remote — ambidextrous |
| **Basketball** | ❌ Poor | Nunchuk movement + Remote shoot = fixed layout |
| **Canoeing / Cycling** | ⚠️ Awkward | Dual Remote/Nunchuk sync — fixed roles |
Some companies made **mirrored Nunchuks** (analog on right, buttons on left) — rare, expensive, unlicensed. Not recommended.
Verdict: For basketball, just play right-handed—it's how the game was tuned. For true lefty sports, stick to **Swordplay, Table Tennis, Archery**.
