I ran for the first time Twilight++, i dind't have it before
But i think that know i don't need it. Ii tried again the games and they perfectly works!!!!
Many thanks guys!!! In order to keep updated my apps like Twilight and nds-bootstrap, how can i do? I mean, using the Universal Updated and updating Twilight, automatically it will be updated nds-bootstrap too? And how can i know it is necessary to update them? Running Twilight i don't see any version anywhere...so i don't know which are my current Twilight and nds-bootstrap version (for sure are the latest one in any case)?
