You already asked that before... It doesn't make a difference if you use FlashMe or not, if a ROM is used to host games, the receiving DS must be flashed.
but i use roms with a passkey (magic key1) with an unmodified ds and it works. so will using noflash me set my ds back to normal?
Indeed, rather than having to use a physical PassMe, FlashMe is a replacement firmware that can boot DS code from the GBA slot. Which is why I flashed my DS instead of buying a PassMe.
And I flashed my DS Lite as I have a Passkey2 that I would rather not have sticking out, and I wasn't going to waste my money on a Passcard3 i didn't need.
I figured something out. Games that are not 1st party nintendo games do not require a signature(bust a move ds). Game that come straight from nintendo(anything with mario in it) do.
No, All 1st party games will have the RSA signiture, MOST 3rd part games will too. only a very small amount won't have the RSA signiture.
