It's time to breathe some new life into the 3DS's predecessor: @shutterbug2000 has just shared a new Nintendo DSi exploit with the community! Called Memory Pit, this release takes advantage of a vulnerability found inside the Camera app to run unsigned code on your device. This makes it compatible with all DSi models, as it works under the latest firmware and also doesn't require any external application to be installed (unlike FlipNote Lenny, for example)! Memory Pit is also very easy to install and run, as it only requires you to copy some files to your SD card and then open the Album inside the Camera app on your console. Keep in mind, however, that booting Unlaunch directly through it won't work: you will have to use HBMenu to launch it instead.

Memory Pit is a new DSi exploit in the DSi camera!
Using it is very simple:
1) Download the attached file and put it in sd:/private/ds/app/484E494A
2) Put the hbmenu.nds file on the root named boot.nds (can't be unlaunch, it won't work. Unlaunch can be booted via hbmenu however)
3) open DSi camera, tap SD card at the top, and tap album
4) Done!

Enjoy modding your DSi!
