Nintendo DS Hacks Guide
Modding the Nintendo DS
The original Nintendo DS and the DS Lite are among the easiest handhelds to mod, because they never required a software exploit in the first place. Everything runs from a slot-1 flashcard: a cartridge shaped like a normal DS game that holds a microSD card. You copy files to the card, slide it into the slot, and the console boots it like any other title.
This means there is no firmware to patch, no brick risk from the console side, and nothing permanent done to the hardware. If you ever want to go back to stock, you simply remove the flashcard. no exploit reversible
What this wiki covers
We walk through identifying your model, choosing a trustworthy flashcard, preparing a microSD card, installing the card's kernel, and booting into homebrew and backups. We also cover the slot-2 (GBA) port, which the DS family shares with Game Boy Advance carts.
If you are brand new, start with What you can do and Is my DS compatible? before buying anything. The single most common mistake is purchasing a cheap clone card that quietly stops working, so the buying guidance here is worth reading first.
Both the original DS and DS Lite are fully supported. The Lite is brighter and slimmer; the original has a sturdier slot-2 port. Either way, the slot-1 workflow is identical.
