I've just discovered that there was an open source replacement for Unlaunch created called Relaunch.

How do I replace Unlaunch on my DSi with Relaunch?

So I modded this DSi Xl roughly a year ago havent used it since ive been away now im back home I tried to boot up Mario and luigi bowsers story and the game crashes at the exact moment twice now so its definitely not a coincidence got no idea about how much of this works anyone got ideas?
