For NDSi/NDSiXL/NDSiLL:

2, insert DSTWO into your console. Boot the console, dont turn off it untill you see the DSTWO cart LOGO(the logo of Fish Tycoon, maybe need about 1 minute). Then re-boot your console.

For NDS/NDSL:
1, copy the correct _dstwo folder and ds2boot.dat file to the root of your microsd card.
2, insert DSTWO into your console. Boot the console, then re-boot when you entered the menu of NDS.
