# Mario & Luigi: Superstar Saga: a matching European GBA decompilation

> Mario & Luigi: Superstar Saga is a matching decompilation of the European GBA release using C compiled with agbcc. Configuration generates comparison assembly from the user's ROM. Decompiled functions are compared with their original instructions, while undecompiled functions come from generated assembly. The author reports a byte-identical combined ROM build.
