How to Reset Bratz: Diamondz Game on Nintendo DS

You likely mean Bratz: Forever Diamondz (2006, DS) — no "Diamonz" title exists.

Reset Save Data (Start Fresh)

1. Boot DS to System Menu (no cart) or hold Start + Select + A + B at boot (some flashcarts).
2. Go to Settings (wrench icon) → Data Management → Nintendo DS.
3. Find Bratz: Forever Diamondz save file.
4. Select → Erase / Delete → Confirm.
5. Reinsert cart → New game starts clean.

If Using Flashcart (R4, Acekard, etc.)

• Save file (.sav) sits beside .nds on microSD.
• Delete .sav file via PC or DS homebrew (Checkpoint, GodMode9).

No In-Game Reset Option

Bratz DS games don't have "New Game +" or "Reset Progress" in menus. Deleting save is the only way.

Backup First (Optional)

Copy .sav to PC before deleting — lets you restore if you change mind.

Same process works for Bratz: Rock Angelz, Bratz: Girlz Really Rock, Bratz: Fashion Boutique on DS.
