You can get the current release right here and install it with a softmodded GC/Wii and GCMM.
The exploit loads a boot.dol installed on your memory card converted with dol2gci (as found in Home Bros) so make sure to also install one with GCMM, it will just crash otherwise.
If you are interested in the source its included on the github page. Please note that some things are very hardcoded so its probably not very readable
