Frogminer Guide


What is Frogminer?

Frogminer is a free CFW (Custom Firmware) installation method for the Nintendo 3DS family of systems.

What will I need to do before I begin?

First, a test. Boot 3DS Download Play and launch DS Download Play (bottom button) and wait 10 seconds. If there is a black screen or error screen, DS mode is bricked and you can't use Frogminer, sorry. If DS Download Play boots as expected, great! Go ahead and complete the Steelminer Guide located here. Keep your movable.sed file, you will need it later on in this guide. NOTE: "Steel Diver: Sub Wars" is a FREE download. It's a different game than the 3DS launch title "Steel Diver" that costs money.
