nds-bootstrap introduce a dldi driver and an arm7 patcher allowing to have some dldi compatibility without flashcard and without recompilation of homebrews. The compatibility is not yet perfect.
Changelog : new arm7 patch that speeds up the dldi speed by 5-10x (depending on the homebrew). Speed now matches a slot 2 device (eg: supercard mini sd).
Extract the zip at the root of your sdcard
It can be configured via the file _nds/nds-bootstrap.ini
I recommand to use a frontend menu to avoid manual ini file modification : nds-hb-menu have just been updated.
