Safety & risks
Modding the original DS family is about as safe as console modding gets, because nothing permanent happens to the console. Still, it helps to understand exactly what can and cannot go wrong.
The console is never at risk. A slot-1 flashcard is just a cartridge. It cannot brick, flash, or alter your DS. Remove it and the console is completely stock. The real risks all live with the card and your data.
What can actually go wrong
- Dead clone cards. The biggest hazard is buying a counterfeit or abandoned card that never works or fails after a kernel update. This is a money risk, not a hardware risk.
- Corrupt microSD data. Pulling the card mid-write or using a fake-capacity microSD can corrupt saves. Always quit to the menu before removing the card.
- Lost saves. Saves live on the microSD, not the cartridge. Back up your save files periodically.
Sensible precautions
- Buy cards and microSD cards from reputable sellers only.
- Test a new microSD card's true capacity before trusting it.
- Keep a copy of your kernel files and saves on your computer.
Follow these and the worst-case outcome is replacing a cheap card. The DS itself will be fine. low risk reversible
