FWNitro replaces your current NDS's firmware which many would call the operation system of the dual screen device. This new firmware will fully replace your old one by flashing it to your device. The installation of this is the same as that of Flashme.

Changes in v1.5:

* Settings in options.h to ignore auto-start flag in NDS card (in case it causes problems or you don't like that function, and this is also what was causing the screen to go black)
* On-screen keyboard functions have been changed a bit: Cursor is displayed after text, color of input text is now highlighted, and Esc key works (same as B button to cancel)
* L and R buttons can be used on main menu to toggle back-light
* You can now call ARM7 functions in PROGRAMMING MODE
