Q. Is this Beta 2?

No, this is a fixed Beta 1 with new stuff.

Q. Where is Mission Mode?

Mission mode isn't available in this rom hack due to its nature.

Q. How do I select alt-skins?

Press L or R while in Kart selection mode to cycle through the character's altskins (works only in VS and TT).

Q. How do I switch to Sanic Mode?

Press Select+Start while in Character selection mode (works in all modes except online).

Q. How do I play online?

You can play online on real hardware or on MelonDS and thanks to Wiimmfi, you can play online very easily.

You only need to change the DNS settings of your connection to one of these two: /

Q. Hey I managed to get online but I see other players running randomly on the map!

Don't play worldwide, if you want to meet other EKDS LE players you shall use Continental (regional) matchmaking, or play with friends.

Q. Does this run on nds-bootstrap? (TWLMenu++ and such)

Yes, it does, unlike Beta 1 versions.

Q. Does this work with Android Emulators?

For some reason, it only works on legit Drastic.

Q. Can I use Mario Kart DS cheats?

Some of the European MKDS codes should work but most of them are broken.

If you want to unlock everything, use a complete savefile.

Q. Hey why can't I open any of the files inside this rom?

The rom has been encrypted in order to block attempts of stealing assets.
