Check here on how to update TWiLight Menu++:
Includes nds-bootstrap v0.43.0
NOTE: Starting with this version, DSiWare saves (.pub and/or .prv files) must be moved to the saves folder, which is in the same location as the .nds file(s), as one of the new features requires you to do so. Create the folder, if it doesn't exist.
What's new?
- For first-time users or for users who have updated to this (or later) version, you can now set your language and region, before using TWLMenu++!
Asynch Card Readsetting has been added!- It is turned on by default, but there's a blacklist in place, preventing certain games from using it, in order to work around bugs.
- You can now select save slots for your DSiWare titles!
- New sound effects for the DSi and 3DS themes!
- MPEG4 Player support has been deprecated, due to it being buggy.
- A better video player and format (by @Gericom) is coming soon.
- (@lifehackerhansol) Added M3 DS Real and M3i Zero autoboot.
Improvement
- (@Epicpkmn11 and various) Updated translations.
Bug fixes
