# Mario & Luigi: Partners in Time: matching DS decompilation

> Mario & Luigi: Partners in Time is a work-in-progress C and C++ decompilation of the European Nintendo DS release, generated with AI under human direction and supervision. The author reports a byte-for-byte ROM rebuild; matching source is gradually replacing assembly, with emulator checks used to confirm game behavior.
